What are the hazards of building a lamp?
The traditional formula of architectural glaze is non-toxic. The main components of Jianzhan glaze are minerals, plant ash and so on. These raw materials are all taken from nature. Plant ash is the ashes of burning plants, and the glaze is mined from the forest hills in southern Yang Nan. The glaze of Jianzhan has three main components: glaze base, developer and cosolvent.

The firing temperature of Jianzhan is very high and its physical and chemical properties are very stable. In Song Dynasty, plant ash was used as the solvent, while in modern times, feldspar and limestone were used as the solvent, all of which were fired in kilns above 1280℃. The firing process of Jianzhan involves many chemical changes of raw materials. At such a high kiln temperature, those heat-labile impurities will be oxidized and volatilized.
When limestone and feldspar melt, building lamps form porcelain. When iron is released, it forms stripes and forms vitrified glaze. This vitrification can protect the glaze color of architectural lamps, with very stable chemical properties, acid resistance, alkali resistance and hot water resistance. /kloc-it is absolutely impossible for tea below 0/00 degrees Celsius to melt glaze.
