High borosilicate glass cups, as an emerging glass material, are widely used in chemical and medical equipment, as well as high-end kitchen utensils production in Europe and America. It is slightly different from ordinary soda lime glass. Handmade glassware, made purely by hand, requires the master to continuously rotate the glass embryo during the blowing process in order to achieve uniform shaping. This is a normal process phenomenon unique to handmade glass products.
1. What is a high borosilicate glass cup
High borosilicate glass is made by utilizing the conductive properties of glass at high temperatures, melting the glass by heating it inside, and processing it through advanced production processes. Due to its coefficient of thermal expansion of (3.3 ± 0.1) × 10-6/K, it is also known as "borosilicate glass 3.3". It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high transmittance, and high chemical stability. Due to its excellent performance, it is widely used in industries such as solar energy, chemical industry, pharmaceutical packaging, electric light sources, and craft jewelry. Its excellent performance has been widely recognized by all sectors of the world, especially in the field of solar energy, which has been widely promoted in developed countries such as Germany and the United States.
2. What are the advantages of high borosilicate glass cups
High borosilicate glass has a high coefficient of expansion. Simply put, it means that the glass cup is immediately taken out of the freezer and filled with freshly opened hot water. The glass cup will not break from minus 20 degrees Celsius to over 130 degrees Celsius, and there is no problem with it. Single layer glass products can be directly put into the microwave oven. I have personally tried it and it can be dried on an open flame for 20 minutes without any problem. High borosilicate Z is mainly used as a glass product, microwave oven supplies, solar tubes, chemical reactors, chemical reaction containers, etc. It is widely used as a safe drinking water product in the world
The water and acid resistance of high boron heat-resistant glass is Grade I, and the alkali resistance is Grade A. The harmful components of the glass are less than 0.1%, making it a widely used heat-resistant glass both domestically and internationally. However, generally heat-resistant glass is not necessarily a true high borosilicate glass, but is replaced with other glass to reduce costs.
Of course, the cost of high borosilicate glass cups is higher than that of ordinary glass cups, so there is definitely a price difference.
