What is the wax used to seal the envelope?

Wax was invented by the Frenchman Russo around 1626. Through experiments, he mixed tar, cinnabar and insect lacquer (Indian natural lacquer) in different proportions and heated them into wax, which was red or brownish red in color. Then he chose a metal mold with a suitable pattern, printed it on the wax that has not solidified, and left a clear pattern after cooling.

Sealant is a kind of adhesive, which is slightly different from the special adhesive for glue and paste. Stationery is often used for fixing, even for daily use, such as avoiding stealing all important documents, sealing a thing and so on. These must be used with wax. The finished wax is a strip-shaped object, which is not easy to be damaged and can be sold without packaging. Packaging is divided into 20 strips or a dozen, which are packaged and sold separately.

Waxes are usually in the form of wax sticks (traditional waxes), but some are waxes with cores and wax particles. When necessary, cut the wax stick into small pieces and put it in a small spoon. After heating and melting, pour it into the required envelope mouth and seal it.

Although wax seal not only has encryption function, but also gives people an ancient, mysterious and high-grade sense of form, many people abandon it because of its complicated manufacturing process.

The wax in China is also called "clay print". It is not a seal, but a precious object preserved from the remains of ancient seals-a dry and hard clay block covered with ancient seals. Because the original seal was a negative seal, the clock became a positive seal on the mud, and its edge was a mud surface, so it formed a wide edge and different edges.
