Perforated cylinders for heat demanding craft

• Perforated vessels in one form or the other are found in ceramic assemblages in most societies from early prehistoric time onwards. They vary greatly in shape and size, indicating a multitude of uses. This paper focuses on a particular type of perforated vessel – the perforated open cylinder, a “vessel” with no base, or rather with rims at both ends. This means that its function as a container is limited and it could only work when standing on a upright surface, e.g. on the ground. Another plausible function could be an extension “pipe”, for example, on a permanent furnace. In this paper we refer to experiments on the use of the perforated cylinder for heat-demanding crafts, more specifically what temperatures can be reached without using bellows – natural draught – in perforated cylinders of different size and shape, and which type of fuel is the most appropriate.
