CALCIUM CARBONATE is a mineral, taken from ground chalk and limestone.
CALCIUM CARBONATE is a salt used in beer brewing as a water adjuster. CALCIUM CARBONATE is best used for dark beers, when the water is deficient in calcium. This will also raise the pH.
It is commonly used in the manufacturing of paper, plastic and paints, due to its adhesive properties as well as its white pigment.
CALCIUM CARBONATE is also used in the building industry in concretes and mortars. It is a source of both carbon dioxide and lime, which can be used in the manufacturing of steel and glass.
In the manufacturing of paper, CALCIUM CARBONATE is a great stabiliser due to its alkalinity. This reduces the acidity of the paper, preventing degradation and improving the lifetime of the paper.
