This chemical is widely used to make glaze, a paint used in the ceramic industry which acquires a glossy appearance on firing.
In brick, tile, pottery ware and earthenware manufacturing processes, barium carbonate is added to precipitate soluble salts such as calcium sulphate with would otherwise cause efflorescence. This is the loss of water of crystallization from a hydrated compound to the atmosphere. Without managing this process, the product will come out from kiln with pin holes and other related defects and would thus have to be scrapped.
