In a one-chamber burning the load of lime material was mixed with fuel and partially isolated from the outside environment. In the case of two-chamber lime burning the fuel is divided from the load most often by an arch created from the material that is being burnt above the hearth. Both methods are known from western Roman provinces (Dix 1982).
Manufacture of lime. Lime stones are burnt in either clamps or kilns. 1. Clamps: For small quantity of limestone, burning is done in a clamp.

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.". Then, when combined with ...
Hydraulic lime sets under water and non-hydraulic lime do not set under water. Quick Lime is a form of lime is manufactured by the burning of stone that has calcium carbonate within it. The burning temperature varies, say 900 degree Celsius and above for several hours. This process is called as calcination.
The slaking is carried out as in case of manufacture of natural hydraulic lime. As this lime is produced after burning twice in kiln, it is also known as the twice-kilned lime.
