Alkaline-earth-containing borosilicate glasses edit In addition to epiphone casino neck width about 75 SiO2 and 812 B2O3, these glasses contain up to 5 alkaline earths and alumina (Al2O3).This compares well with soda lime glass, which can withstand only a 37 C (99 F) change in temperature and is why typical kitchenware made from traditional soda-lime glass will shatter if a vessel containing boiling water is placed on ice, but Pyrex or other borosilicate laboratory.Borosilicate is widely used in implantable medical devices such as prosthetic eyes, artificial hip joints, bone cements, double hit casino free dental composite materials (white fillings) 7 and even in breast implants.6 Borosilicate glass has a wide variety of uses ranging from cookware to lab equipment, as well as a component of high-quality products such as implantable medical devices and devices used in space exploration Health and science edit Borosilicate beakers Virtually all modern laboratory glassware.Rapid prototyping edit Borosilicate glass has become the material of choice for fused deposition modeling (FDM or fused filament fabrication (FFF build plates.Cristal d'Arques, Hartzviller, Cristal de Sèvres, Cristalleries Royales de Champagne, Saint Louis, Daum, Baccarat en Lalique.Dat hoeft bovendien geen lood te zijn, zinkoxide, bariumoxide of kaliumoxide is ook goed.Schott AG, which has sold borosilicate glass later under the brand name.
