Remains of a calciner used in the production of arsenic. It has been vacant for many years and is vulnerable with a damaged main roof and a collapsed adjoining tin-roofed extension. The main hipped slate roof of the building has been damaged through vandalism and there is an urgent need for weather proofing.
