Because of the stable silica-oxygen chain, the chemical status is very steady. Besides, white carbon black is a acid oxide, thus it has some features of acid oxide. For example, it can react with alkali in high temperature. White white carbon black has great acid resistance and will not react with it. But it can be corroded. Therefore, people use it to carve glasses.
