1. Understand the basic knowledge of ceramic tiles
Newbies in the industry, hehe~~~~~ I’ll give you a few words of shame as a senior! !
In fact, the professional knowledge of ceramic tiles cannot be understood by you in a few words, because it is designed to cover a wide range. I personally feel that as a shopping guide, the first thing you need to learn is How to tell the quality of a ceramic tile? If you don’t even know how to tell the quality of a ceramic tile, how can you convince your customers that you are professional? And you are most persuasive when you introduce products to customers in a neutral and objective manner in a specialty store, instead of being like a lower-level salesperson who only knows how to sell melons. You have the basic knowledge of ceramic tiles. My friend upstairs has already told you in detail. Let me give you some practical tips, that is, how to choose the quality of ceramic tiles:
There are roughly two styles on the market: antique tiles. And polished tiles, it doesn’t matter which tiles you buy, what matters is how you choose them. These methods are used by people in the industry to test the quality of tiles. Although it cannot be said that you can choose good tiles 100% of the time, at least 80% of them are correct. of! Just remember a few points when choosing ceramic tiles. Others are not important:
1. Look at the back of the swivel to see if the color is pure. Generally, the pure color is milky white (white) and cannot turn black or black. It must not turn yellow, let alone have black spots on the surface. Black and yellow color indicates that the brick itself has impurities. If there are too many impurities, the density of the brick will definitely decrease, and it is prone to breakage and damage during normal use. However, it is not normal if the back of the brick cannot be very white, which means that too much zirconium silicate raw material is used. One of the national tests for whether the ceramic tiles are radioactive is to detect the practical amount of zirconium silicate raw material. Zirconium silicate raw material can make bricks It turns white and bright, but the raw material zirconium silicate is also one of the main killers of radioactivity, so you must pay attention. Generally, regular manufacturers have national inspection report certificates. You can just ask them to show it. Note: it must be a color certificate bound in a photo frame or the parameter indication at the back of the product brochure. It is not a copied inspection report. That thing is Can be counterfeited.
2. Check whether the particles on the side of the ceramic tile are fine and uniform. If the particles are large and rough, the density of the brick will be loose, and problems will definitely occur during use. Here is a simple example: when you get the house Generally, in rough houses, the walls are made of cement and are very rough. When you use putty powder, the walls become smoother and more delicate. Just use this standard to look at it.
3. Stand the bricks up and tap the bricks with your hands. The crisper the sound, the higher the density of the bricks and the better the quality. The duller the sound, the worse the density of the bricks, and the poorer the stain resistance and resistance of the bricks. The durability is even worse.
4. If you are buying polished tiles (large floor tiles above 600 specifications), touch the front surface of the tiles with your hands (touch with the back of your hand). The smoother it feels, the fewer pinholes there are on the surface of the tiles, and the resistance will be higher. The higher the stain resistance, there is no need to worry about anti-slip issues as long as it is not used in the bathroom or kitchen.
5. For the same color, look at the glossiness of the brick surface. Generally, large floor tiles are placed on sloping boards, with spotlights or fluorescent lamps on them. You need to see how these light bulbs are placed on the surface of the bricks. The shadow (just like looking in a mirror), the clearer the shadow, the higher the glossiness of the brick, the stronger the hardness of the brick body, and the higher the durability. On the contrary, the blurr the shadow of the light bulb, the lower the hardness of the brick. Note: What I am referring to here are polished tiles, and they must be of the same color when comparing. You cannot compare yellow tiles with white tiles. That is wrong.
6. If you are buying antique bricks, you can also touch the front of the brick with your hands to feel whether the glaze on the brick surface is fine, and then use your eyes to look closely to see whether the glaze particles are rough, etc. . When buying antique tiles, you must pay special attention to the quality of the glaze. If possible, ask the salesperson to explain the glaze production process in detail, because glaze is the life of antique tiles, and color is the soul of antique tiles, so you must pay more attention to the color. Compare the products to see if the color is pure. It is basically OK to choose a product with a relatively pure color.
7. If you are buying porcelain tiles (wall tiles), you should look at the thickness of the glaze between the embryonic body and the glaze on the side of the tile. Do not buy it if it is too thin, because it will become damaged over time. There may be breakage or leakage. Then check whether the glaze on the surface of the porcelain tile is bright. The glaze is bright and of good quality.
The above methods 1, 2, and 3 are common to all bricks, while 4, 5, 6, and 7 are methods for different products.
Finally, I would like to add a few words about the weight of bricks. The heavier the bricks, the higher the density. However, this is not useful for all bricks. For example, Oceano and several other big brands now seem to have a product called "lightweight bricks". "The product is very light but of good quality. Therefore, the comparison of weight can only be used for traditional ceramic tile products. If conditions permit, take a cup of water and pour it on the back of the brick to see how quickly the brick absorbs water. The faster it is, the worse the brick is, and the slower it is, the better the brick is. This is what is commonly known as the water absorption rate of ceramic tiles. It is generally an international standard. Below 0.4%, that is, pouring 100 grams of water into the brick will only absorb 0.4 grams. Bricks that meet this standard are basically good bricks. Special reminder: Some sales staff put bricks upright and then dropped them. The sound was very loud but the bricks were fine. Damn it. . . . . Forget it, anyone with some knowledge of physics knows this. . . . . Haha~~~~
Okay, I’ll share it here first, I hope it can help you. If you still don’t understand, leave a message to me and I will reply~~~
2 .Tile knowledge training
1) Currently, ceramic tile products on the market are mainly divided into the following categories according to the materials used and production processes:
Mosaics are mainly divided into glass mosaics ( The raw material is glass) and ceramic mosaic. Mainly used to decorate walls.
Glazed tiles are composed of a tile base and a layer of glaze on the surface. That is, glazing is applied to the ceramic base and fired under high temperature and pressure. The glaze of the tile is mainly to increase the beauty of the ceramic. role.
Glazed tiles are divided into floor tiles and wall tiles according to the location of use.
According to their smoothness, they are divided into matte glazed tiles and bright glazed tiles. At present, most of the floor materials use matte glazed tiles.
Vitrified tiles (or polished tiles) are made of soil embryos (or soil embryos with some ore powder added) and are fired at one time under high temperature and high pressure. The surface of the vitrified tiles is basically the same as the raw materials used in the bottom embryo. (Except vitrified tiles with special craftsmanship, such as the new glazed series of vitrified tiles). Vitrified tiles are all-ceramic ceramic products. Its wear resistance and flexural strength are very high, and its water absorption rate is low (the water absorption rate of vitrified bricks is less than 1‰). Vitrified tiles are mainly used as floor materials. In the past, vitrified tiles were mainly used as wall materials in high-end hotels and offices. But now, with the improvement of living standards and consumer consumption levels, vitrified tiles are used in homes for kitchens. There are more and more families using wall covering materials. ]
2) According to the water absorption rate of ceramic tiles, they are mainly divided into the following three types:
Ceramic: refers to ceramic products with a water absorption rate of ≥6%, mainly used for wall decoration .
Half ceramic and half porcelain: refers to ceramic products with a water absorption rate of ≥3% and <6%.
All-ceramic: refers to ceramic products with a water absorption rate of <3%, which can be widely used for wall and floor decoration.
3) It can be divided into the following types according to different use occasions:
Interior wall tiles: ceramic materials used on indoor walls;
Floor tiles: used Ceramic products placed on the ground;
Exterior wall tiles: ceramic materials used for building exterior walls and balconies;
Square tiles: ceramics used in large outdoor squares and sidewalks. product. Of course, this classification method is not complete. For example, vitrified tiles can be used as floor tiles, interior walls, and even exterior walls. However, glazed interior wall tiles are not suitable for use on the ground, mainly due to their poor wear resistance. Difference.
3. Professional knowledge of ceramic tiles
Ceramic tiles are made of refractory metal oxides and semi-metal oxides through the processes of grinding, mixing, pressing, glazing and sintering. A kind of acid and alkali resistant porcelain or stone construction or decorative material, generally called ceramic tiles.
Its raw materials are mostly mixed with clay, quartz sand, etc. Ceramic tiles are classified according to their uses: exterior wall tiles, interior wall tiles, floor tiles, square tiles, industrial tiles, etc. They are classified according to molding: dry-pressed molded bricks, extruded molded bricks, and plastic molded bricks. According to fired ingredients: oxidative tiles, reducing ceramic tiles. According to the glaze application: glazed tiles, unglazed tiles. According to the water absorption rate: porcelain tiles, stoneware tiles, fine stoneware tiles, stoneware tiles, ceramic tiles. According to the type: glazed tiles, full-body tiles (homogeneous tiles), polished tiles Brick, vitrified tile, porcelain glazed tile (antique tile) Tile terminology 1. Glazed tile: Ceramic tile with glazed front.
2. Unglazed tiles: unglazed ceramic tiles. 3. Flat decorative tiles: ceramic tiles with a flat front.
4. Three-dimensional decorative tiles: Ceramic tiles with concave and convex patterns on the front. 5. Ceramic mosaic tiles: Ceramic tiles (also called mosaics) made up of multiple small bricks that are used to decorate and protect the floors and walls of buildings.
6. Square tiles: ceramic tiles used to pave squares and roads. 7. Polished tiles: Ceramic tiles that have been mechanically ground and polished and have a mirror-like luster.
8. Infiltrated tiles: Ceramic tiles that infiltrate soluble colorant solutions into the body and display colors or patterns after firing. 9. Antique bricks: Different from polished bricks and porcelain tiles, they are "born" with an "old" face. Therefore, people call them "antique bricks". There are also retro bricks, classical bricks, pan-antique bricks, and porcelain bricks. Quality glazed tiles, etc.
The essence of antique tile design is to reproduce "nature". Ceramic tiles have the same size, which saves construction time and is neat and beautiful.
Water absorption: The lower the water absorption, the better the degree of vitrification, the better the physical and chemical properties of the product, and the less likely it is to crack or peel due to thermal expansion and contraction due to climate change. Smoothness: The surface of ceramic tiles with good flatness will not bend or peel. No warping, easy to construct, and the ground will be flat after construction.
Strength: high flexural strength, good wear resistance and heavy pressure resistance, not easy to wear, durable, suitable for use in public places. Color difference: Place the tiles flat on the floor, arrange them into a square meter, and check whether there are different shades of color or inability to connect, causing aesthetic obstacles.
Comparison of porcelain tiles: 1. Porcelain tiles. Six major advantages of quality bricks: Low water absorption: Low water absorption, only less than 0.08%, which is 5-30 times lower than European standards and natural stone. It can be used for many years without discoloration, leaving no traces. High wear-resistant system, high temperature, always looks like new. Fired, Mohs hardness reaches level 8, and its wear resistance is.
4. Common knowledge about floor tiles
Wall and floor tiles are collectively called ceramic tiles, generally referred to as ceramic tiles.
p>
National standards are specifically classified according to water absorption rate: 0%————0.5%————3%————6%————over 10% porcelain brick stoneware ceramic tiles fine stoneware bricks. The water absorption rate of stoneware bricks and ceramic bricks is related to the properties of the bricks. Generally, bricks with lower water absorption rates have higher density, better strength and stronger frost resistance.
(Also known as high-quality bricks or concrete. Quality bricks) Note: Ceramic tiles with high water absorption do not have frost resistance requirements. Ceramic tiles are divided into glazed bricks and unglazed bricks.
Glazed tiles generally use ceramic tiles with high water absorption. Glazing not only changes the surface decoration effect, but also improves the performance, making it smooth, smooth and wear-resistant, non-absorbent and airtight. However, it is generally not suitable for flooring because glazed tiles are too smooth and have high surface friction. Small. Especially after being wetted, it becomes slippery.
And once the glaze is worn, it will also have a great impact on the quality and decorative effect.
For example, in terms of applicable decorative surfaces, there are interior wall tiles, exterior wall tiles, interior and exterior floor tiles, square tiles, etc. In terms of function, there are ordinary tiles, tiles, belt tiles, parquet tiles, yin and yang corner tiles, etc.
In terms of surface treatment, there are matte tiles, glossy, polished (vitrified), anti-slip, etc. In terms of decorative properties, there are art tiles, antique tiles, cultural stones, etc.
< p> Ceramic tiles are one of the oldest decorative materials. People first chiseled stones and laid them on the indoor floor. Later, they used ceramics to bake them into similar shapes to decorate their rooms.In ancient Rome, ceramic tiles appeared in public bathrooms and homes. After thousands of years of evolution and development, ceramic tiles have become one of the most common decorative materials due to their hardness, resistance to moisture, acid and alkali resistance, and easy cleaning.
Indoor ceramic tiles can be divided into: wall tiles and floor tiles according to the location of laying. Strictly speaking, wall tiles are ceramic products, while floor tiles are porcelain products. Their physical properties are different. Therefore, the selection of clay ingredients and the firing process are very different between the two. The water absorption rate of wall tiles is about 10%. The water absorption rate is several times higher than that of floor tiles with a water absorption rate of only 1%.
Nowadays, in order to pursue personalization, some families use materials ingeniously and unconventionally, such as breaking up colorful wall tiles and laying them on the bathroom floor, and then pasting plain and elegant floor tiles. wall. In fact, floor tiles and wall tiles should not be mixed. Doing so is neither scientific nor safe.
Because the floor is often washed with large amounts of water, it is possible to ensure that the tiles are not affected by water vapor and do not absorb stains. Floor tiles have low water absorption and are suitable for laying on the ground.
Wall tiles are made of glazed pottery, which has a relatively high moisture content. Its back is generally rough, which facilitates the adhesive to stick the wall tiles to the wall. Floor tiles are not easy to stick firmly on the wall. When wall tiles are used on the ground, they will absorb too much water and become difficult to clean.
It can be seen that wall and floor tiles are not suitable for mixing. Ceramic tiles are one of the most consumed materials in home decoration, so consumers are always very cautious when purchasing them.
It is a good idea to go to a building materials supermarket to buy. B&Q Building Materials Supermarket ensures product quality while constantly introducing new products, giving consumers the greatest choice. It is understood that B&Q is currently holding the "Tile Consumption Culture Festival", so go and have a look.
Floor tiles generally refer to ceramic tiles. Ceramic tile is a kind of ceramic product. The clay is mixed with different materials. It is cut, dehydrated and air-dried, and then fired and pressed at high temperature to make bricks of different shapes.
The tiles can be left unmodified and have a rough surface, or they can be glazed and fired to create smooth tiles. General glazed ceramic tiles have the advantages of being waterproof, moisture-proof, wear-resistant, and easy to clean. They are most suitable for damp or hygienic spaces such as kitchens and bathrooms.
In fact, there are many types of ceramic tiles suitable for floor decoration. The common ones include mosaic high-temperature bricks, over-the-floor bricks, clay bricks, etc. Mosaic Mosaic is the smallest of all kinds of ceramic tiles, and is commonly known as a brick.
It was originally an architectural decorative art material in ancient Europe. Generally speaking, it is only used to pave kitchens and bathrooms in homes, or swimming pools in public places. Because of its small size, it is paved as a floor and is not easy for people to slip. It is especially suitable for slippery environments.
In fact, mosaics have quite a lot of choices in terms of materials and colors, and they have great potential in creating aesthetics. As long as they are designed appropriately, they can create good visual effects. High-temperature bricks The most popular floor tile material in recent years is high-temperature bricks.
High-temperature bricks are ceramic tiles made with high temperature and high pressure. They have higher wear resistance than ordinary ceramic tiles used for flooring, so they are very suitable for use as floor decoration materials. Generally, the surface of high-temperature bricks is quite smooth, but the surface of high-quality bricks has been specially treated so that it is not easy to slip even if it is wet with water.
Due to the attractive color and smooth texture of high-temperature bricks, many families began to use them to lay the floors of their living rooms. In addition to appearing in kitchens and bathrooms, high-temperature bricks also began to appear in halls. Over-the-bottom tiles Most ceramic tiles are composed of glaze and tiles. If the quality is poor or the tiles are worn for a long time, the glaze on the surface will be scratched or peeled off, exposing the underlying tiles, which cannot be repaired.
Over-the-bottom bricks make up for this shortcoming. This kind of brick is made entirely of the same material, regardless of the bottom layer and the surface layer. Even if it is scratched and worn, it will not reveal another color of material, affecting the appearance; and this kind of brick has strong wear resistance. , suitable for floors with high traffic volume, so many people now use underlay bricks to lay floors.
Transparent tiles are available in matte and glossy finishes. The glossy tiles are also known as glossy tiles. The surface is polished to create a smooth mirror surface with a marble effect. Clay Bricks In addition to the above-mentioned ceramic tiles, many people who advocate local flavor choose clay bricks (red bricks) with a simple and natural appearance to pave their floors. They are more commonly used in sunshine and gardens, and are also used in halls.
Clay tiles are unglazed floor tiles, giving them a simple texture. In addition, crystal oil can also be added to protect the surface and add a smooth feel.
5. How to choose ceramic tiles at home when decorating
As the saying goes, "cheap products are not good, and good products are not cheap." But for decoration, if you choose expensive ones, you must have quality. A good attitude is like a piece of fish left to be slaughtered on the chopping board of the building materials market. Because there are many types, patterns and sizes of ceramic tiles, many people spend most of their time selecting ceramic tiles when decorating.
Types of ceramic tiles
Ceramic tiles are roughly divided into polished tiles, antique tiles, porcelain tiles, glazed tiles, full-body tiles, microcrystalline stone and other types (see picture)
After having a general understanding of the ceramic tiles on the market, we can choose ceramic tiles accordingly.
Living room ceramic tiles
For practical people, dirt and wear resistance should be the first choice basic performance of ceramic tiles. In most living rooms, especially in living rooms where guests are greeted and many people come and go, All require ceramic tiles that are hard enough and resistant to wear and tear. This is also the reason why most people choose polished tiles as living room tiles.
Living room background wall
Microcrystalline stone is a high-end ceramic tile material that has become popular in recent years. It has exquisite texture and bright color. Many owners will choose to use microcrystalline stone ceramic tiles to decorate the TV background wall. Luxurious and grand, it can instantly enhance the taste of your living room.
Choosing kitchen wall tiles
For kitchen walls, you should choose scrub-resistant tiles. For kitchen walls, you should choose wall materials that are easy to clean and not easy to stain with oil. They should also be fire-resistant and resistant to thermal deformation. Waiting for tiles. Although there are alternative products such as fireproof boards, glass, and coatings on the market, ceramic tiles still occupy the mainstream market.
Choose glazed tiles as the kitchen wall. The glazed surface is transparent, acid and alkali resistant, and has a complete isolation effect on oil stains, preventing the growth of bacteria, odors, scale, and mucus. The surface of glazed tiles is divided into two types: gloss and matte. Gloss is easier to care for.
Matching ceramic tiles, flower tiles, and waistlines make the overall combination more transparent and warm
Kitchen floor tile purchase
Choose full-body tiles, front and back materials Consistent with the color, it has good anti-slip and wear resistance. Generally people call it "anti-slip bricks", which are found in lobbies, aisles and outdoor walkways.
Bathroom tiles
Commonly used wall and floor decorative materials in bathrooms include glazed tiles, vitrified tiles, and mosaics. Bathroom wall tiles must be covered with ceramic tiles that are highly waterproof, corrosion-resistant and anti-mildew. It is recommended that floor tiles choose ceramic tiles with a certain friction but shallow texture, which are non-slip and avoid hiding dirt, and are less laborious to clean.

6. A large collection of ceramic tile classification knowledge
A large collection of ceramic tile classification knowledge ? Are you talking about the collection of ceramic tile classification knowledge? Before, we first introduce to you a black technology in the decoration industry, Nalut gold diamond grinding stone.
To prevent the growth of bacteria, the gold diamond grindstone can also release negative oxygen ions, making people feel refreshed and happy. Seamless cement gold diamond grindstone and silica grindstone are composed of three materials: Nalute special cement mortar, concrete sealing and curing agent and wire concrete sealing and curing agent.
Can you now introduce the collection of ceramic tile classification knowledge in detail? 1. Ceramic tiles are divided into floor tiles, wall tiles and waistline tiles according to their functions. Floor tiles: According to the design and color, they are divided into imitation Spanish tiles, vitrified polished tiles, glazed tiles, anti-skid tiles and seepage polished tiles, etc.
Wall tiles: According to the design and color, they can be divided into vitrified wall tiles and printed wall tiles. Waistline bricks: mostly printed bricks.
In order to match the specifications of wall tiles, waistline tiles are generally set in a format of 60mm*200mm. 2. Ceramic tiles are divided according to technology: glazed tiles, full-body tiles, polished tiles, vitrified tiles, and ceramic mosaic tiles.
Glazed bricks: refers to bricks with a glaze layer on the surface. This kind of bricks are divided into two categories: one is fired with clay; the other is fired with porcelain clay. Currently, about 80% of buyers for home decoration choose this brick as a floor decoration material.
Full-body tile: This is an unglazed porcelain tile with good slip resistance and wear resistance. Most of the so-called "anti-slip floor tiles" are full-body tiles.
Because this kind of brick is moderately priced, it is very popular among consumers. Polished tiles: Full-body tiles become polished tiles after polishing. This type of tile has high hardness and is very wear-resistant.
Vitrified tile: This is a kind of porcelain tile fired at high temperature and is the hardest of all ceramic tiles. Sometimes when the polished tiles are scratched, the vitrified tiles are still intact.
Ceramic mosaic tiles: also known as mosaics, they have many specifications, are thin and small, are hard in texture, are acid-resistant, alkali-resistant, wear-resistant, impermeable, have strong pressure resistance, are not easily broken, have various colors and are widely used.

7. How should you answer if a customer asks how good your ceramic tiles are?
When a customer asks how good your ceramic tiles are, you can consider the label, appearance, splicing effect, and percussion listening. , weigh the importance, compare varieties, ceramic tile corners and other aspects to introduce to the other party.
1. Check the label
The glaze of good quality ceramic tiles should be smooth and delicate, the gloss glaze should be crystal clear and bright, and the matte glaze should be soft and comfortable. Under sufficient natural light or fluorescent lighting, if the brick is placed 1 meter away and observed vertically, no obvious glaze defects should be visible. Patterned brick patterns should be delicate and realistic, without obvious defects such as lack of color, broken lines, and misalignment. The shading and trademarks on the back of high-quality ceramic products are clear and complete, with few glaze marks or defects.
2. Take a closer look at the appearance
The glaze of good quality ceramic tiles should be smooth and delicate, the gloss glaze should be crystal clear and bright, and the matte glaze should be soft and comfortable. Under sufficient natural light or fluorescent lighting, if the brick is placed 1 meter away and observed vertically, no obvious glaze defects should be visible. Patterned brick patterns should be delicate and realistic, without obvious defects such as lack of color, broken lines, and misalignment. The shading and trademarks on the back of high-quality ceramic products are clear and complete, with few glaze marks or defects.
3. Splicing effect
The size deviation of good ceramic tiles is small. Place a batch of products vertically on a flat surface to see if there is any unevenness. To check the flatness, you can put the edges of two bricks close together to see if there are any gaps. A good product will have little deformation, and the brick surface will be smooth and beautiful after paving. To look at the color difference of the product, put a few bricks together and examine them carefully under sufficient light. If the products have different shades of color, the overall effect after paving will be poor.
4. Tap and listen
Tap the tile gently and listen carefully to the sound. Products with better quality will sound crisp and sweet. Products of poor quality will make an "empty" sound when knocked due to improper raw material formula, short firing cycle, and low firing temperature.
5. Weigh the weight
Weigh the weight of the ceramic tiles. Generally speaking, ceramic tiles of the same specifications that are heavier have lower water absorption and better intrinsic quality.
6. Comparative varieties
Floor tiles are divided into glazed floor tiles and unglazed floor tiles according to the glaze condition. Glazed floor tiles are mainly used for floor decoration in bathrooms and kitchens, and are used in conjunction with interior wall tiles. Most floor tiles are surface polished and become polished tiles. Most polished tiles have a water absorption rate of less than 0.1% and are also called vitrified tiles. The surface of polished tiles is as smooth as a mirror and is a high-end ceramic product.
7. Corners of ceramic tiles
When selecting ceramic tiles, randomly select a few pieces and look at them along the edges and diagonals of the ceramic tiles. If you find that there is "warping", , it means that the flatness of the tiles is not enough. If not, it means that the flatness of the tiles is basically passed.
Expansion:
Ceramic tiles, also known as tiles, are made of refractory metal oxides and semi-metal oxides through the processes of grinding, mixing, pressing, glazing and sintering. A kind of acid and alkali resistant porcelain or stone, construction or decorative materials, called ceramic tiles. Its raw materials are mostly mixed with clay, quartz sand, etc.
8. Professional knowledge of ceramic tiles
Ceramic tiles
The so-called ceramic tiles are made of refractory metal oxides and semi-metal oxides, which are ground, mixed and pressed. The process of glazing and sintering to form an acid and alkali resistant porcelain or stone construction or decorative material is generally called a ceramic tile. Its raw materials are mostly mixed with clay, quartz sand, etc.
