Improved Furnace (Kiln)

Description
"Logs flamed in the wide fireplace, for there was a frosty edge to the air, and a great meat pasty in a stone platter stood smoking on a broad mahogany board."

- The Hour of the Dragon

Designed to heat ore to incredibly high temperatures in order to extract pure metals, furnaces require fuels such as coal or wood and ores for processing and catalysts such as Steelfire for strengthening. Intense heat can also be used to harden certain types of stone and a furnace can be used in conjunction with other concoctions to create hardened stone bricks.
