Hand Blown Borosilicate Wine Glasses

Borosilicate glass is a type of glass with the main glass-forming constituents silica and boron oxide. Borosilicate glasses are known for having very low coefficients of thermal expansion(~3 × 10−6 /°C at 20°C), making them resistant to thermal shock, more so than any other common glass.

In addition to the quartz, sodium carbonate, and aluminum oxide traditionally used in glassmaking, boron is used in the manufacture of borosilicate glass. The composition of low expansion borosilicate glass such as those laboratory glasses mentioned above is approximately 80% silica, 13% boric oxide, 4% sodium oxide, and 2-3% aluminum oxide. Though more difficult to make than traditional glass due to the high melting temperature required, it is economical to produce. Its superior durability, chemical and heat resistance finds excellent use in chemical laboratory equipment, cookware, lighting and, in certain cases, windows.

1. All our products are able to endure sudden temperature changes from -20°C to 150°C in extremely short time

Questions: Are this kind of glass wares safe ? Does they easily broken and fragile ?

Answers: Borosilicate glasses are known for having very low coefficients of thermal expansion(-20°C--150°C), making them resistant to thermal shock, more so than any other common glass.In addition,it is much lighter in weight but more solid in molecular structure,thus even with small thickness,it also could reach high strong intensity and so more durable than traditional soda lime glass.

C&C Glass uses high quality borosilicate glass and pay more special attention to the thickness of products,make them thicker but firm and comfortable when you hold them.Therefore,C&C products are one of the most safest and popular products in the market

2.Sophisticated Hand Blown Craftsmanship,Uniform Mold

As a more advanced glass material,Borosilicate glass were widely used in Chemical and Medical industry and High end Kitchenware in most European and American countries.With sophisticated mouth blown craftsmanship,workers needs to constantly rotate the glass embryo in order to heat the glass uniform.This is the most significant special features of hand made glasswares compared with other glasswares

3.Clear borosilicate glass which is free of smell and flavor,does not discolor and show high chemical and mechanical resistance.Therefore it is eco-friendly and safety to human body
