This second operation is analogous to that practised in Sudan and elsewhere at present, but instead of the whole pot being covered with chaff and other material which produce a pot entirely black on the rim only would have been covered as only this and the interior had to be blackened. G.G. Majumdar (pp. 90- 93) is also of the opinion that the BR pottery can be made only by the double firing process. Lucas (pp. 434-36) actually manufactured a few pots by employing this technique. The pots coated with a thin wash of red ochre were baked in a small electric muffle furnace. And when red hot, placed mouth downwards on a layer of sawdust in which the rim was buried. The result was a red pot with a black rim and generally, though not always, a black interior, but the red body was almost always badly smoke stained. In this process, however, the thin red wash which was applied to the pot, could be discerned even in that part of the pot which was black by merely scraping the surface and the same could also be noticed in the section.
