Heat-Efficient Furnace

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

The heat-efficient furnace is comprised of a short hearth in the shape of an inverted pyramid centered beneath a stone chimney. A moveable cap on the chimney peak affords the smith a greater degree of temperature control, reducing the waste of base materials and lowering the cost of forged items.
