Material intrduction
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.
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.
How to evaluate the glassware
1.Material: Excellent choice of materials glasses, should see less than a star point-like, cloudy
and flocculent distribution of gas-liquid inclusions. Texture to the pure, smooth, glistening
as well.
2.Work: Crystal wine glass processing mill workers. Work a good crystal glasses should be
elegant and refined, not only fully demonstrated crystal products outside the United States
(shape, style, symmetry, etc.), but also to maximize the mining their inner beauty (crystal).
3. Polishing: Polished a direct impact on the worth of crystal glasses. Crystal wine glass to
go through in the process of emery pondering rough production makes crystal surface
friction traces. Good crystal glasses natural transparency, gloss is better than, say jargon
is "attempting foot.
Why you choose us-Perfect Glasses?
1. All our products are able to endure sudden temperature changes from -20°C to 150°C
in extremely short time.
2. 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.
3. Perfect glasses 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.
