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.
Borosilicate Glassware Features and Advantages
1,they are heat resistant,suitable for use in microwave,dishwasher and stove
2,offer a variety of application possibilities: baking and cooking, preparing and serving, cooling and freezing (down to -35°C/-31°F)
3.show a high resistance to sudden temperature changes with a temperature difference of 140°C/284°F(three times as high as normal glass or lead crystal glass)
4,are produced from clear borosilicate glass which is free of smell and flavor,does not discolor and show high chemical and mechanical resistance
5,do not give off any substances and therefore are suitable for allergy sufferers
6,are easy to clean and hygienic in use through the pore-free surface
7,come in superior and functional product design for an optimal preparation of beverage and meal
8,are most suitable as an individual and creative gift idea
he champagne flûte (fr. Flûte à Champagne) is a stem glass with a tall, narrow bowl. The bowl of a flute may resemble a narrow wine glass as seen in the illustration; or a trumpet shape; or be very narrow and straight-sided.
C&C Glass Champagne Glass
As with other stemware, the stem allows the drinker to hold the glass without affecting the temperature of the drink. The bowl is designed to retain champagne's signature carbonation, by reducing the surface area at the opening of the bowl. The flute has largely replaced the champagne coupe or saucer, the shape of which allowed carbonation to dissipate even more rapidly than from a standard wine glass. Its smaller diameter also allows more flutes to be carried on a tray.
Nucleation in a champagne glass helps form the bubbles seen in champagne. Too much nucleation will cause the carbonation to fizzle out quickly. A smoother surface area will produce fewer bubbles in the glass, and more bubble texture in the taster's mouth.
Why Us ?
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
Present market Glasswares Grades
Top Quality High borosilicate glass: is approximately 80% silica, 13% boric oxide, 4% sodium oxide, and 2-3% aluminum oxide. It show high resistance to sudden temperature changes with a temperature difference of 170°C(-20°C---150°C)
Recycled borosilicate glass: with less than 20% silica,and contaminated to environment and human body
Normal Glass:contains too many complicated impurities and with machine mass production
C&C Glass products are all made of top quality high borosilicate glass,with superior heat resistant and eco-friendly quality
