Hydrofluoric acid is very strongly corroded glass, so we should not use glass equipment containing hydrofluoric acid experiments. 

The lye, especially the hot lye, is significantly corroded against the glass, and the lime storage of the glass instrument is a grinding instrument that can also be opened and can not be opened. Therefore, the glass instrument can not be stored for a long time lye.

The chemical composition of glass are mainly SiO2, CaO, Na2O, K2O. Usually the introduction of B2O3, AL2O3, ZnO, BaO and other substances to change the nature of the glass to meet the different needs. In general, heat-resistant burner glass products, contain high SiO2 and B2O3, are high borosilicate glass, such containers of high thermal stability, acid, water resistance, alkali resistance slightly worse. General instrument glass and gauge glass is soft glass, thermal stability and corrosion resistance slightly worse. Quartz glass is a special instrument glass, its physical and chemical properties and glass are different, it has extremely excellent chemical stability and thermal stability, but the price is more expensive.

Nitric acid - hydrofluoric acid lotion: 50ml of hydrofluoric acid, 100ml nitric acid, 350ml of water mixed, stored in plastic bottles in the tight. The use of hydrofluoric acid on the corrosion of glass effectively remove the glass, quartz containers on the surface of the metal ions. However, this lotion can not be used for washing meters, glass sand core filters, absorption cells and optical glass parts. Use protective gloves when used.
