chemical formula: CaCO3
( fine powder )
carbonate is widely used medicinally as a stomach antacid and an
ingredient in toothpaste. It can be heated to form 'Quicklime' which is
then added to water. This forms another material known as 'Slaked Lime'
which is a base material used throughout the chemical industry. In
pyrotechnics, it's used to color flames orange. Calcium Carbonate makes a
rock-hard adhesive when mixed with an equal amount of Zinc Oxide, and a
little Sodium Silicate to form a paste. This rapid setting adhesive is
typically used to plug firework tubes.
