Chunnam is a term that can be found in the Indian and Southeast Asian context, specifically in the Tamil and Malayalam languages. Chunnam, also spelled as chuna or chunnambu, refers to a traditional form of lime paste that is commonly used in various construction and industrial processes.
Typically made by burning shells or limestone, chunnam is produced by calcinating or heating these materials at high temperatures until they turn into a white powder. This powder is then mixed with water to form a smooth paste. Chunnam possesses several advantageous properties, such as its binding ability, fire resistance, and durability, making it a valuable material in construction and masonry work.

Moreover, chunnam is utilized in traditional lime washing, a technique where a mixture of chunnam and water is applied to walls to give them a smooth and elegant finish.
