IS 15751 (2007): Calcite for ceramic industry
Calcite, the essential mineral in limestone is a naturally occurring calcium carbonate having formula CaCOl, consisting of 56.03 percent CaO and 43.97 percent C02. It is normally white in colour and soft, the hardness being only 3 in Mohr's scale. In pottery, calcite is used in glazes. It is used in the manufacture of silica refractories as

Stone Paper? Fountain Pen Friendly?
When ground into powder the harder minerals will be ground along with the calcite, making it much more abrasive to the tipping material, if limestone or marble is the source of the calcite. If the calcite used to make the paper is calcium carbonate precipitated from solution, so the particles are pure, it should not harm the tipping material.

The role of calcium carbonate in cement hydration
Many studies use high levels of calcite, such that most of the calcite acts as a filler. Studies using lower additions, 1–10 wt.%, confirm that mineralogical changes result but are not readily comparable with the approach developed here. An analysis and interpretation of the literature will be presented in a subsequent paper [13].
