Whiting is the commonly-used name for calcium carbonate (CaCO3), which is the most common source of calcium in glazes. It is a high temperature flux which gives durability and hardness to glazes.
'Whiting' is a very general material name, and may be used to refer to branded versions of calcium carbonate, including Vicron, Marblewhite, and Atomite. When you order whiting from The Ceramic Shop, you will receive Oldcastle brand Castle Carb, which is a fine-mesh whiting.
