Calcium carbonate is an ionic solid, composed of carbon, oxygen, and an ionically bonded calcium di-cation, as previously discussed. It is relatively insoluble in water, except in environments of salt water, in which it dissolves into its constituent polymorph forms of calcite and aragonite through a dissolution-precipitation process, though other polymorph forms exist [ 26 ].

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, it has a high surface tension.
