It is globally renowned for its high chemical and thermal resisting properties. The bearers of these properties are well developed mullite crystals, not only increasing the softening point but also ensuring both high mechanical resistance and low co-efficient of thermal expansion, the result of which enables the porcelain to withstand high thermal shocks. To assure continued high quality, only the highest grade raw materials are used. The high softening point of laboratory porcelain makes it possible to use glazed articles under suitable conditions at temperatures up to 1100ﾰC +. Squat Form without Lid 11ML Pack of 10.
