- Feb 05, 2018 -

Multi-purpose glassware made of soda-lime silicate glass, colorless and transparent containers, the iron content of glass is generally less than 0.02%. Add colorants in the glass raw materials, can be made of colored glass; Add opacity, opal glass (see glass). Production of carved carved high art vessels such as goblet, perfume bottles, fruit pots and more potassium lead silicate glass, also known as lead crystal glass. This glass contains PbO, with a high refractive index and dispersion, grinding brilliantly extraordinarily bright, high specific weight, percussion crisp sound. PbO30% or more for the all-lead crystal glass, lead-containing PbO24 ~ 30% lead crystal glass, containing PbO18% below the low-lead crystal glass, in addition to BaO containing barium crystal glass. Cooking utensils such as coffee pots and other products using heat-resistant borosilicate glass, its low thermal expansion coefficient, high temperature resistance. Glass-ceramics have better resistance to heat and temperature gradients, high mechanical strength, and are suitable for the manufacture of utensils often washed in cooking utensils and hotel rooms.
