Mainly include: ①Pre-processing of raw materials. glass saucepan, Crush the bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) to dry the wet raw materials, and remove iron from the iron-containing raw materials to ensure the quality of the glass. ② Preparation of batch materials. ③Melting.  The glass batch material is heated at a high temperature (1550~1600 degrees) in a tank kiln or a crucible kiln to form a uniform, bubble-free liquid glass that meets the molding requirements. ④Forming. Process liquid glass into products of required shapes, such as flat plates, various utensils, etc. ⑤ Heat treatment. Through annealing, quenching and other processes, the internal stress, phase separation or crystallization of the glass is eliminated or generated, and the structural state of the glass is changed.

Frosted glass processing method: first lay the flat glass to be processed on a workbench with a mat or cotton blanket, and then pile an appropriate amount of fine emery on the glass surface, use a coarse porcelain bowl to buckle the emery, light with both hands Press the bottom of the bowl and push it in a circular motion. You can also use higher grade terrazzo ground grinding stones. The grinding operation should start from the four peripheral corners and gradually move to the middle, until the glass surface is ground into a uniform milky white, and it can be transparent and not see-through.

  Silver photo-engraved glass processing method: first wash the flat glass with water and dry it, then coat it with paraffin wax, then carve out various patterns on the paraffin wax, and corrode the glass surface with a 1:5 concentration of hydrofluoric acid solution. Finally, pour the hydrofluoric acid to remove the paraffin, and wash the glass with water until it is clean.

  Others, such as colored glass, can be processed by mounting or spraying, and the specific method is omitted. Snap lines on the ground and vertical walls, make the lower wall structure, the frame column beams fixed, glass processing, cutting and installation of the upper and all wood (metal) frames, glass installation, border painting and cleaning.
