Using the high quality raw materials from both domestic and abroad, such as the silica sand, soda ash, salt cake, dolomite, etc. as our material and then sent to furnace after accurate weighting, checking and mixing, with heavy oil as fuel. They are melted into glass liquid under the high temperature of 1600~1700 centigrade degree. After refining the glass liquid is cooled and flows to the Tin Bath, floating on the surface of tin liquid. Then the shaped glass is annealed in the lehr and comes out as top quality glass to meet our customers' requirements.
