Walkersville in Frederick County, Maryland — The American Northeast (Mid-Atlantic)
Chemistry in the Kiln
CaCO3 + Heat = CaO + CO2↑
Calcium Carbonate (Limestone or Bluestone) + Heat = Calcium Oxide (Quicklime, or Burnt Lime) + Carbon Dioxide
The procedure caused the stone to become lighter in weight, have fewer impurities, and become easier to pulverize into smaller sizes or into powdered lime.
The kilns are approximately twenty-one feet deep and eight feet in diameter. Woody Handley, who lived at the kilns from 1935-1950, and was for a time the kiln manager, told of personally relining each kiln with new brick every couple years as the lining corroded and broke down.
Erected by Frederick County Parks & Recreation.
