High boron heat-resistant glass has water resistance and acid resistance of grade one, alkali resistance of grade A, and harmful components of glass is less than 0.1%. It is a heat-resistant glass widely used at home and abroad, but general heat-resistant glass is not necessarily real borosilicate glass, and It is replaced with other glass to reduce costs.
Many families are gradually adopting beautiful and high-quality heat-resistant glass products to replace traditional ceramic products, which has become a fashion in developed countries. Heat-resistant glass tableware and cooking utensils mainly include heat-resistant tableware, heat-resistant utensils and cooking utensils, which can be divided into open flame utensils, dark flame utensils and hot water utensils.
Glassware for open flames is mainly composed of super-bottom borosilicate glass, and the thermal shock strength can reach 400 ℃ or more. It is mainly used for direct open flame heating, cooking and withstanding rapid heating and cooling. For example, frozen food can be stored together with the container Use open fire, dark fire, electric stove to directly heat and cook. There are also some heat-resistant glass products, the thermal shock strength of which is above 150 ℃, which is mainly used for direct open fire heating or cooking. The glass products for dark fire have a thermal shock strength of 120°C or higher. They are mainly used for heating cooking without direct fire, such as ovens and microwave ovens.
