Material introduction
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.
Double wall glass introduction
Thank you for purchase of the high quality C&C brand borosilicate glass double wall insulated beverage glassware,which is made according to the highest standards in quality and durability.
All pieces of C&C brand double wall borosilicate glass insulated beverage glassware is made from borosilicate glass in double wall structure.While preventing you from burning your hands when filled with hot beverages and eliminating sweats on the outside when filled with cold drinks,it keeps your beverage hot and cold for a longer duration than traditional glassware in single wall structure.
Borosilicate glass is a special type of glass renowned for its superior resistance to chemical corrosion,heat,thermal shock and scratches.In addition,it is much lighter in weight but more solid in structure and so more durable than traditional soda lime glass.Thus,C&C brand borosilicate glass double wall insulated beverage glassware weighs so light even in double wall structure and remains durable even with the two layers of thin walls.Due to the properties of borosilicate glass,the glassware remains clear throughout its life span.)
