Below is a list of Quartz Glass manufacturers from Paulsboro, New Jersey. Quartz glass is made from silicon dioxide and is a highly pure material that looks similar to standard glass but has superior thermal and optical properties and thus is used for a number of specific applications. Quartz glass does not have a crystalline structure; rather it is amorphous and produced from silicon compounds during the vaporization stage of the chemical reaction. It is one of the purest materials used in industrial applications today and its purity is what gives it excellent high temperature and visibility properties.
