Calcium carbonate has a very high loss on ignition 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.

An introduction to SEDIMENTARY ROCKS. Sedimentary rocks form from sediment. Sediment is a general term that indicates loose grains (such as the sand at the beach) and chemical precipitates (such as crystals of salt). Sedimentary rocks can be subdivided in three categories clastic, chemical, and biochemical sedimentary rocks.

Characterisation of limestone and lime. 5.1 Limestone 5.1.1 Composition. The main component of limestone is calcium carbonate (CaCO3), also known as calcite, which is formed by the compaction of the remains of coral animals and plants on the bottoms of oceans. It varies from a soft white substance (chalk) to a very hard substance (marble).

Limestones containing between 25 and 50 percent clay particles are called marls. There are also transitional formations between limestones and sandstones. Natural chalk is also a limestone, consisting of 9699 percent CaCO 3. The metamorphism of limestone leads to the formation of marble. Transitional varieties are called marmorate limestones.
