The old Toledo style furnaces that were used at University of Kansas were made of brick in a rectangular fashion but the floor sloped to the back of the furnace to make it easier to get all the glass out. Don't remember if they mortared it to the bottom or some how added wedge bricks as the furnace was being built.
