Calcium Carbonate

Calcium Carbonate is a pure form of limestone ground into a powder. It is used mainly to provide an alkaline reserve in paper which promotes longevity. It is useful as a filler to retard shrinkage in paper castings and to make a smoother surface, and in sheet forming to improve opacity and whiteness.

�As an alkaline reserve to assure archival qualities: DIRECTIONS: Use 1 tablespoon per pound of dry fiber. Slowly add powder to water and mix for 2 minutes. Stir evenly into pulp. Best results when added to the beater at the beginning of the cycle.

�As a filler to reduce shrinkage or increase opacity: DIRECTIONS: Use 1 cup per 3 pounds of dry fiber. Mix with 1 gallon of water, stir evenly into pulp. Note: If results are not satisfactory, add more calcium carbonate. Remember to mix with water before adding to pulp.
