Brunton's Arsenic Calcining Kiln

This is a nice, mostly complete calcining kiln. A waterwheel provided power for the gearing sited in the front opening. A table rotated five times an hour heating the cassiterite ore to 600 degrees celsius. The cassiterite (tin ore) was collected off the table, the arsenic was condensed in a flue to the left and scraped off.
