Ethan Brand -- What Is a Limekiln?

Bartram is a lime-burner who works a limekiln, just as Ethan Brand once had. So, what's a limekiln? Here's a little info:

A lime kiln is a type of furnace that burns marble, limestone, or another material to produce lime, a solid made up of calcium oxide (CaO). If it is free of impurities, it is white and is called pure lime or quicklime. When mixed with water, lime turns into a powder, calcium hydroxide—Ca(OH). Lime is used in the production of cement, paper, glass, whitewash, and agricultural preparations that reduce the acidity of soil.
