Dolomite is a rock-forming carbonate mineral with a chemical composition of calcium magnesium carbonate (CaMg(CO3)2). Dolomite is a metamorphic sedimentary rock. The colour is often white, but may contain greyish veins.
Basalt is a dark, fine-grained lava rock, consisting mainly of feldspar (plagioclase) and the pyroxene (augite).
Quick lime, calcium oxide (CaO), is produced in high shaft kilns, rotary kilns or in annular kilns by heating limestone, calcium carbonate (CaCO3), to around 1,200 °C: CaCO3 = CaO + CO2.
Slaked lime is produced by adding water to quick lime. Quick lime is produced by heating limestone to around 1,200 °C.
Limestone is a type of rock composed mainly of calcium carbonate (CaCO3). Limestone is formed under high pressure and heat over a long time.
