Glassware is colorless and transparent vessel made of sodium-calcium silicate glass.The iron content in glass is generally less than 0.02%. Colored glass can be made by adding a colorant to the glass material. The manufacture of high-quality glassware such as goblet, perfume bottle, fruit bowl and so on is made of potassium lead silicate glass, also known as lead crystal glass. This glass contains PBO, with high refractive index and dispersion, grinding the edge of the surface to bring extra bright, high specific gravity, tapping when the crisp sound. Containing pbo30% above for all lead crystal glass, containing pbo24-30% for medium lead crystal glass, including pbo18% below is low lead crystal glass. There are also barium crystalline glass containing BaO. Cooking utensils such as coffee pots and other products using heat-resistant borosilicate glass, its thermal expansion coefficient is low, resistance to temperature blast crisis strong. Glass-ceramics have better heat resistance and temperature-resistance, mechanical strength, suitable for the manufacture of cooking utensils and hotels often washing utensils.
The manufacturing of glassware is to put the glass composition of the powder and clinker into the crucible kiln or pool kiln (glass melting furnace) melting, clear into a uniform bubble-free, stone-free, non-striped glass liquid, and then cooled to adapt to the corresponding molding method required viscosity range, for various molding operations.
