Calcium oxide - Wikipedia
Calcium oxide (formula: Ca O), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature.
Lime kiln - Wikipedia
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide). The chemical equation for this reaction is CaCO 3 + heat → CaO + CO 2
Why Burn Limestone? - Oldknow’s
Mar 20, 2017 · Limestone is made of the chemical calcium carbonate and was formed by compression of the shells of dead sea creatures at the bottom of clear, tropical seas over millennia.
Lime (material) - Wikipedia
Otherwise it most commonly means slaked lime, as the more reactive form is usually described more specifically as quicklime or burnt lime. In the lime industry, limestone is a general term for rocks that contain 80% or more of calcium or magnesium carbonate, including marble, chalk, oolite, and marl.
Burning the bones of the earth: lime kilns - Resilience
Oct 1, 2013 · Limestone is mainly coral and shells of long-extinct sea creatures, squeezed over aeons into a solid mass of calcium carbonate, or CaCO3. When burned at 900 degrees C or more it vents carbon dioxide (CO2), leaving behind the volatile calcium oxide (CaO) – “quicklime,” “burnt lime” or “unslaked lime.”
Quicklime - Preparation, Properties, and Applications with FAQs
Quicklime is a calcium oxide formed to release carbon dioxide by calcinating calcium carbonate (limestone). Quicklime is also referred to as handpicked lime, burnt lime, lump lime, calcining lime, and caustic lime.

Calcination - Burning Limestone - Unity Lime
‘Preheating zone’ – limestone is heated to approximately 800°C by direct contact with gases leaving the calcining zone. ‘Calcining zone’ – fuel is burnt in preheated air from the cooling zone. This produces heat at above 900°C and turns limestone into quicklime and CO2.
Burning Lime, The Traditional Way - LimeWorks.us
Dec 18, 2023 · This is an incredible video that really shows the difficulties of burning limestone the old way. Stacking wood, limestone and coal in an old kiln these men go through the process using traditional methods to turn regular limestone into caustic burnt lime.
Calcium Oxide: From Ancient Warfare to Modern Industry
May 20, 2021 · Calcium oxide, a common chemical compound that appears as a white crystalline solid at room temperature, is easily attainable through the thermal decomposition of limestone. This was how the material, also known as quicklime, was acquired for human use, after ancient peoples burned limestone in a kiln to take advantage of its structural properties.
