There are many kinds of sparks, which can be divided into:
Soft sticker, hard card, label, glass card, mother-child card, special-shaped card, book card.
It can be divided into early flowers (before 1949), middle flowers (1950s and 1960s), cultural revolution flowers (10) and modern flowers (after the Cultural Revolution). In addition, there is a fake flower, which is a printed matter that imitates early flowers and is reissued without obvious signs.
Sparks can be classified and collected, generally by country, city and autonomous region. For example, there are nearly 20 match factories in Guangdong Province. Or according to the classification of sparks, the sparks of the same theme are classified into one category, such as scenery, sports, people, animals and so on. Can also be classified according to spark varieties, divided into three categories: soft paste, hard card and volume label; It can also be classified according to art forms and genres to facilitate the comparison between the same art forms. In a word, how to classify sparks depends entirely on one's personality and hobbies, and there is no uniform and fixed model.
Collecting sparks, like collecting stamps, also pays attention to appearance, which not only directly affects the value of sparks, but also affects the scores of exhibitors. When collecting sparks, we should do a good job of "four precautions" to prevent mildew: in wet weather, we should watch as little as possible, keep the room dry and ventilated, and check the collected materials regularly to see if there is adhesion and mildew. Once moldy, don't be exposed to the sun; Dust-proof: don't expose the collection, hide it in a paper bag and then hide it in a box; Insect prevention: put moth-proofing agents in boxes and bags for storing collections; Fire prevention: Keep away from fire sources and don't smoke when sorting out the collection.
Once the spark is stained with oil stains and sweat stains, you can put a piece of rice paper on the spark and gently use an iron to go back and forth a few times. When the spark is mildewed, add a little salt to the boiled milk, soak the mildewed spark after cooling, then rinse it with clear water and drain the water. There is some dirt on the spark, which can be gently wiped with absorbent cotton dipped in alcohol.
