Laguna Calcium Carbonate (Whiting) in Bulk is a white powder.
It is available in a 50-lb container.
Calcium Carbonate, also known as whiting, is a common chemical used in everything from building material to diapers to paints.
It is the most common source of calcium in glazes.
When fired in a kiln, it is a high temperature flux that gives glazes durability and hardness.
Ground calcium carbonate is is an abrasive, but is not hard enough to scratch glass, many metals, or ceramics.
Alone, it is quite refractory, but when it is mixed with feldspar or silica, it will start fluxing when it reaches around 1100°C.
