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).

optimal particle size to use to obtain maximum shell quality can vary (Rabon and Roland, 1985). Unfortunately, there are no detailed research data to show the best ratio of particle size with fine granular limestone. Most research workers used approximately *h of the CaCOi source as large particles and lh as finely ground. However, in the
