A clome oven (or cloam oven) is a type of masonry oven. It has a removable door made of clay or alternatively a cast-iron door, and was a standard fitting for most kitchen fireplaces in Cornwall and Devon. The oven would be built into the side of the chimney breast, often appearing as a round bulge in the chimney. This bulge consisted of the masonry surrounding the oven, and was intended to be dismantled should the oven ever need to be replaced. During installation, they are surrounded by packed clay to prevent the actual oven cracking.
