This is a nice, mostly complete calcining kiln. A waterwheel provided power for the gearing. 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 and scraped off. This view shows the coal grates.
