MAKING LIME MORTAR
Ruins of a lime kiln, in Rockwoods Reservtion, Missouri,
show how lime mortar was made in the 1850's.
The lime was used to make cement and mortar
for area homes and buildings.
This kiln was producing lime in 1856,
and required two ingredients plentiful in the state:
limestone (from nearby bluffs) and
fuel (firewood from surrounding woods.)
It was common for early settlers to establish
rock quarries and lime kilns, as they settled
and built towns along Missouri's rivers.
Kilns were operated 24-hours a day,
reaching temperatures of 800˚,
which transformed limestone rock
into powdered quick lime,
the essential ingredient for cement.
Powdered lime was also used to "sweeten"
farm fields to increase crop productivity.
