Currently, it is mainstream borosilicate glass plate (hard glass plate).
The Pyrex glass sheets have been discontinued, and currently, Tempax sheets are used as a substitute. Tempax is a glass sheet from the German company Schott, and it is a very beautiful glass sheet that has a smaller coefficient of thermal expansion compared to ordinary soda glass, demonstrating heat resistance and thermal shock resistance in various fields. Dimension cutting and edge finishing... approximately 7-10 days Tempax tempered glass finishing... approximately 2-3 weeks

Company information
In 1907, we established a private business, a scientific glass processing plant, in the Kita Ward of Osaka City. Subsequently, in 1957, we reorganized into a corporation in line with the development of the business, becoming what is now Fuji Rika Kogyo Co., Ltd. Our main operations have been the production of glass products and the sale of scientific instrument manufacturer products. For over 100 years, we have steadily progressed alongside scientific glass and scientific instruments. However, we will cease operations at the end of June 2024 and will begin operations in July under MIZUKEN Co., Ltd. (formerly the Comprehensive Water Research Institute).
