The Pate
Knowes Smelter was originally built in 1746, over the year's additional hearths
and features had been added, so that in the end it had five scotch hearths, two
roasting furnaces, one slag hearth and a reverberating furnace. A water wheel
inside the furnace house was used to drive bellows for all hearths and an
exhaust fan for the fumes. In 1780 an additional water wheel was built on the
north face of the smelter for the purpose of mechanically crushing ore on
site.
During its operational life, 1764 to 1845 it is estimated that the
total amount of lead smelted at Pate Knowes was approximately 63,000 tonnes.
The larger smelt mill at Meadowfoot finally replaced the
smelter.
