Glass is actually a very common daily necessities, but it is beautiful, but it has a lot of beauty.

"The color is gorgeous but not flashy, transparent and opaque, mysterious and simple, hard but fragile, refraction light also changes light". These are all descriptions and praise of glass, which is precisely because of these diverse characteristics, so that it can meet people's visual desire to the maximum extent and give people the highest level of visual enjoyment.

"The key theory of gegu" records: "if the pseudocrystal is burned, the color is dark and green, the eyes are angry, or there is yellow and green color, and there are also white ones, which are clear and clear, which is called NiTi."

Compendiumofmateriamedica records: "when the drug is burned, it is called nitrate with the eye of Qi and light weight."

The "NiTi" recorded in ancient China is glass, while Japan has taken the Chinese character "NiTi" to date.

Baidu on the introduction of NiTi is: "use ore burning made of the pseudocrystal."

The development of nitrates in Japan combines the technology of Britain and Bohemia, and adds the characteristics of their own countries and tastes, forming a unique style of their own.

Although the processing technology of modern nitrate is more complex, but because of the late maturity and popularization, there are still a large number of old shop workshops to date. Except for this state, Okinawa Ryukyu nitrate and Hokkaido koutaru are the famous places of origin of nitrate technology.

How is nitrate made?

Every nitrate is born through various complicated process procedures such as burning, melting, blowing, cutting and grinding. To get a clear, delicate and smooth nitrate, it is very testing the level of craftsmen.

Any slight change in the process may affect the formation of the final product. But it is also because of this feature that the nitrate craftsmen can make more personalized works.

The production of nitrate is divided into two processes: hot processing and cold processing.

The heat treatment is to heat the raw materials at high temperature for about 30 minutes, then mix them, and put them into the kiln for high temperature burning at a temperature of more than 1500 degrees. When the nitrogen is melted into clean nitrate without bubble impurities, the nitrate in soft state can be taken out and blown with stainless steel blowing rod.

The raw materials of nitrate processed by blowing rod need to be made by the craftsman on the working table. The nitrate in manual rotation will be cooled slowly in the air, so as to form.

Another kind of cold processing is the process of solid cooling, cutting is one of the common techniques. The traditional Japanese technology is such as "slicer", which is divided into Edo and Samo.
