1, heat-resistant material: can be heated with candle alcohol;
2, high transparency: full transparent glass material, can directly see through the brewing process, appreciate the beauty of tea / flowers / fruit stretch;
3, the original taste reappears: due to the characteristics of the glass hairless pores, will not absorb the taste of the flower tea, so that you can taste 100% of the original taste, and easy to clean, the taste does not remain.
4, elegant style: designed for brewing flower tea, crystal texture, you can see the light tea color of herbal tea, fully enjoy the fun of drinking tea.
The product mainly adopts high-quality borosilicate green glass with a 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 PNYEX-7740 glass of Corning Company of the United States. This kind of glass is widely used in the production of advanced automatic feeding, immersion temperature measurement, furnace bottom bubbling, mechanical agitation, electric assisted dissolution, laser technology and electronically controlled tunnel kiln. The instantaneous temperature difference is -20 degrees to 150 degrees. The best chemical stability, low expansion coefficient and high temperature impact resistance are the most remarkable features of this type of glass products. It is comparable to the glass products of European and American countries, and its quality is stable. It is mainly exported to Japan, Europe and America.
The borosilicate glass tea set is a heat-resistant glass tea set that can be heated by an open flame and heated in a microwave oven.
Process: One of the most common molding methods in glass manufacturing, which can be divided into manual blowing and machine blowing. Manual blowing is commonly known as "blowing a big bubble." In the 5th century, this technique was transmitted from Central Asia to China, which stimulated and drove the development of China's glass manufacturing process. Since then, China has used the blowing method to manufacture hollow glassware, namely glass containers. The method is to first draw the glass melt from one end of the copper or iron blowing cylinder, and then blow the gas at the other end of the blowing cylinder to form the desired shape of the melt, and finally cut it with scissors. During the blowing process, the technician's hand keeps rotating the blower, on the one hand to keep the glass melt from escaping, and on the other hand to use the viscous flow of the glass to shape the desired shape. In the meantime, coordination and cooperation must be achieved, and the product can be perfected, which is quite difficult. The size, thickness, shape, and the like of the glassware are controlled and controlled depending on the amount of blown air, the degree of urgency, and the rotational speed of the blower.
Mold blowing: Relative to moldless blowing, first use copper or iron to make a hollow model, then use the blower to draw the glass melt, and put it into the mold to blow until the melt completely fills the model inner wall. After cooling, the mold is ready. In this way, it is possible to manufacture a special shape such as a square or a polygonal shape, and a complicated part such as an ear, a mouth or a foot required for the object. Mold blowing greatly enriches the shape and artistry of the object
