Popular around St. Day
In tin production, ore was roasted above 300°C to remove impurities such as sulphur and arsenic which otherwise made the cast tin brittle. If arsenic was desired, fumes from the calciner passed through a long flue known as a 'lambreth' or labyrinth, where the gas cooled and condensed, forming arsenic crystals on the walls. When sufficient had collected, the calciners were stopped, iron doors in the lambreth were opened, and the arsenic ‘soot’ was swept off the walls and shovelled out. Workers put wads of cotton wool in their nostrils and a cloth over their mouths. and followed strict washing regulations, but still experienced skin irritations. Some workers were believed to have developed partial immunity, and folklore suggested arsenic improved complexion and hair condition. The lambreth had a tall stack at the end to create a strong through draught and also to reduce the damage caused by the noxious fumes.

Built in 1897, this calciner was used to roast arsenic ore - check out the date above the archway. Arsenic gas was driven off by the heat and travelled towards the stack higher up the hill and through the labyrinth, or lambreth, where it condensed on the walls.

Impressive industrial remains, a great place to walk but note the warning signs related to the tailings from Mount Wellington, in the lagoons, which contain heavy metals and arsenic.
