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.

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
