Here's the inside of the metal barn where I do my casting.  From left to right you can see the propane tank, the torch (for lighting the furnace), the fire extinguisher, the furnace and casting area, the sandbox, and some of my flasks, bottom boards, and supplies.   The white bucket is filled with water for washing off castings.  The slight greenish tint is due to the fact that the only source of light is a couple of big openings up near the roof fitted with translucent green fiberglass "windows"...
