Sand Bath in a Sunk Iron Pan
A sand bath is a pan of sand set over the heat. A flask or dish bedded in the sand is warmed on all sides, not just on the bottom. Alchemists already used it. Here a shallow pan is hammered from iron sheet into a hollow and then filled with sieved sand.
The picture: our diagram of a flask bedded in sand in an iron pan over a fire.
