lime-kiln
Definition
- Noun:
- A "lime-kiln" is a kiln or furnace used to produce quicklime (calcium oxide) by heating limestone (calcium carbonate) at high temperatures. This process, called calcination, drives off carbon dioxide, leaving behind the reactive quicklime used in construction, agriculture, and chemical industries.

- Noun:
- The workers loaded the lime-kiln with limestone and fuel to begin the burning process. (A furnace for making quicklime.)
- Abandoned lime-kilns can still be found in rural areas where limestone was once quarried. (Historical structures used for lime production.)
Advanced Usage

- In the 19th century, entire families often operated a lime-kiln to supply building materials. (They managed the kiln for commercial lime production.)
"lime-kiln waste": the byproducts (e.g., ash, unburned limestone) left after calcination.
- The lime-kiln waste was sometimes used as a soil conditioner. (Residue from the kiln.)
