After firing, the kiln should be removed from the microwave oven and placed on heat-proof surface while it is allowed to cool. Microwave kilns are limited in size, usually no more than 20 centimetres (8 in) in diameter. [12] Top-hat kiln: an intermittent kiln of a type sometimes used to fire pottery. The ware is set on a refractory hearth, or ...
This pottery is handmade, and potters dig clay locally to produce their wares. Tempering agents like sand, volcanic ash, or pieces of ground-up broken pottery are combined with the clay to harden it during the firing process. The vessels are then pit-fired in the ground. Wood, dung, coal, or other locally sourced materials are used as fuel. [7] [8]
In the case of a tabun oven where there was no top opening, a layer of fuel (usually dried manure) is spread on the outside of the shell and lid.

Pottery has been used to make cookware from before dated history. [22] Pots and pans made with this material are durable (some could last a lifetime or more) and are inert and non-reactive. Heat is also conducted evenly in this material. They can be used for both cooking in a fire pit surrounded with coals and for baking in the oven.

Burnishing gives pottery a reflective surface without having to use a ceramic glaze. [5] It is described as a low-tech way of finishing pottery because burnished pottery needs to be fired below 1832F (1000C), which is different from firing glaze. [5] Burnishing can also be a step towards preparing pottery for pit firing, saggar firing, or raku. [5]
