To ensure the high quality, Sunny Glassware has stringent requirements for material,all the glass material for glassware are used with food grade high borosilicate glass, its main performance indexes reached the international ISO standard, the material are the same as 7740 of Coming Incorporated. Compared with common glass,it is environmental health, non-toxic side effects, its mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance and other properties is greatly increased, high borosilicate glass has very low thermal expansion coefficient, high temperature resistant, resistant to 200 degrees of temperature change,it is the best choice for making glass. The quality of cleanliness each made like the delicate and transparent as crystal glass.
Pure manual craft
There are many types of the method of making glass, in order to meet customer demand, Sunny Glassware can choose different process according to the customer requirements, borocilicate glass adopts pure hand-made, technical difficulty is bigger, the processing process more complicated, but the products from Shenzhen Sunny glassware Co., LTD. are excellent quality with solid wood color, fruity, smooth and bright.

Cutting
Cutting technology unique, a glass tube after 650 ° flames of fire are then cut into two, each strand is a glass, the glass bottom unaware tiancheng, fruity and smooth after cutting out. Each glass tube after cutting out with the fire is "benchmarking of pyrex glass" , it will not lead to rupture because of the temperature difference of upheaval.

Double welding
Two layers of glass were welded together under 650°c fire burn melt, perfect transition, flawless and bubble, the glasses would not burst under the the bad environment or scalding hot water, unique and air insulation double-wall structure, can keep the temperature of the tea soup, good heat insulation and prevent hot.

Polishing
Every rim of the glass was manual polished under the fire, so as to guarantee every rim was fine and smooth, it tastes good when drinking. Manual polishing glass is not only pure and transparent crystal, but also environmental health.
