Green ecological glass tea set

Product material: high borosilica glass

Expansion coefficient: 3.3

 Instantaneous temperature difference: between -20 and 150 degrees

Product quality: Excellent material (made of high borosilicate glass, non-toxic and tasteless, without any contamination to food), passed the Green Food Hygiene Law inspection

Processing technology: handmade, advanced equipment, the oldest craftsmanship, and integration of modern technology

Process notes: Purely handmade glass products, there are slight differences in size/shape/weight/thickness, individual bubbles are normal process phenomena, they are all blowing processes, you can buy with confidence.If you have any concerns, please purchase with caution!!!

The product mainly uses high-quality borosilicate glass with an expansion coefficient of 3.3. Its physical and chemical properties meet the German DIN standard and the American ASTM-E438 Class A standard, which is equivalent to the PYREX-7740 glass of the American Corning Company.A series of advanced technologies such as push-type automatic feeding, immersion temperature measurement, furnace bottom bubbling, mechanical stirring, electric dissolution, laser technology and electronically controlled tunnel kiln are widely used in the production of this kind of glass.The instantaneous temperature difference is -20 degrees to 150 degrees. Good chemical stability, low expansion coefficient, and high temperature impact resistance are the most significant features of this type of glass product.It is comparable to glass products in European and American countries, with stable quality, and is mainly exported to Japan, Europe and the United States and other countries.
