Chalk is a type of sedimentary rock primarily composed of calcium carbonate (calcite) and formed from the accumulation of microscopic marine organisms’ remains, primarily coccolithophores. While chalk is a distinct type of sedimentary rock, it can be classified in various ways based on different criteria: Chemical Classification:The core ingredient of all gypsum plasters is gypsum rock–hydrous calcium sulfate–which has a water content of about 20% in chemical combination. During processing, about 3/4 of this chemically combined water is removed from the gypsum rock employing a controlled heating process called calcination. Limestone is a relatively soft rock with a Mohs hardness of 3, which means it can be easily scratched. It has a specific gravity of 2.7-2.9, which makes it less dense than most other rocks. It is typically soluble in acidic solutions, which is why limestone landscapes often feature caves, sinkholes, and other karst formations. Type of Limestone…
