Calcium carbonate Wikipedia

OverviewUsesChemistryPreparationStructureOccurrenceGeologyCalcination equilibrium

The main use of calcium carbonate is in the construction industry, either as a building material, or limestone aggregate for road building, as an ingredient of cement, or as the starting material for the preparation of builders' lime by burning in a kiln. However, because of weathering mainly caused by acid rain, calcium carbonate (in limestone form) is no longer used for building purposes on its own, but only as a raw primary substance for building materials.

Limestone Wikipedia

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

Calcium Carbonate

Calcium carbonate has a very high loss on ignition (LOI) and for this glaze, the gases of its decomposition are coming out at the wrong time. While there likely exists a firing schedule that takes this into account and could mature it to a perfect surface, the glaze is high in MgO,

Limestone

The calcium carbonate used in ceramics is simply limestone ground into a powder (not calcined and is therefore stable). While not intuitive (given the high LOI and propensity to regenerate), in some countries (e.g. Thailand) limestone powder (about 10-20%) is added to clay bodies (fired 700-900C).
