化學玻璃用來製造化學工業、製藥工業和化學實驗室里的玻璃儀器,如燒杯、燒瓶之類。這種玻璃具有高度的抗水性,能抵抗化學藥品的侵蝕(氫氟酸除外),同時因為它的熱膨脹係數很小,能經受溫度的急劇變化而不致破裂;還有很好的耐機械碰撞能力。但是由於這種玻璃在熔製时的溫度比普通玻璃要高得多,並且它的玻璃溶液的黏滯性很大,吹製器皿的操作也就比较困 Chemical glass is used to make glass instruments in the chemical industry, pharmaceutical industry, and chemical laboratories, such as beakers, flasks, and the like. This glass has a high degree of water resistance, can resist the erosion of chemicals (except hydrofluoric acid), and because of its small thermal expansion coefficient, can withstand sudden changes in temperature without cracking; also has good resistance to mechanical impact . However, since the temperature of the glass at the time of melting is much higher than that of ordinary glass, and the viscidity of its glass solution is large, the operation of the blowing vessel is relatively difficult.
