For example, Sallie Bassham examined it in some detail during a study of the environmental impact of lead smelting. She speculated on the possible use of a condenser and described the settlement pits etc which were used to recover lead fume. She also drew attention to two short, mined sections in an extension of the flue, dating from around 1866.
Grassington Lead Mining Trail Walk - Walking Englishman
Here a sign explained "When lead is smelted, some escapes as tiny particles called fume in the waste gases from the furnaces. Condenser Houses were built to slow down these waste gases and make it easier to collect the lead fume for re-smelting". Nothing valuable went to waste then. Following the flue towards the smelt mill chimney
