Description

The calciner at the west end of the buddle floor of the West Basset Stamps, located on the North Wheal Basset settlement, is a Grade II listed double Brunton calciner from 1898, which has since fallen into disrepair. Constructed from coursed square granite and small rubble, it is currently roofless. The building has a rectangular shape aligned on a north-south axis and features two chambers designed for 16-foot rotating inclined tables. It is a single storey structure with two segmental-headed openings on each side wall and round-headed openings at ground level on the end walls. There are also remnants of a connecting flue leading to a chimney at the north end. Historically, this calciner was used to burn off impurities from tin-ore concentrate and is now considered a functionally and visually integral part of a group that is likely unique in Cornwall.
