There are several types of trademarks commonly printed on ceramic vessels.

The first one is to add an underglaze mark on the bottom of the product before firing, and it will be on top after firing. The disadvantage is that the clarity is poor and the color variety is relatively small, but it saves trouble.

The second method is to use decorative paper to bake the bottom of the product after producing the white tire. This method has good definition and bright colors, but it requires one more process.

There is also a manufactured product that is directly covered with a kind of oil seal. This kind of oil seal generally cannot be washed away, but it still has the problem of fading after a long time of use, and there is only one color and cannot be used. Very clear.
