Sand with clay: There are many different types and colors used in pottery to give texture and colors to clays.
Sand with firing: When firing large heavy objects, like tiles, they should be laid out separately with a thin layer of sand between the shelf and the tiles, this is to help their movements as they shrink during firing.
Salt is a sedimentary material consisting of small, often rounded grains or particles of disintegrated rock, smaller than granules and larger than silt. The diameter of the particles ranges from 0.0625 to 2 mm. Although sand often consists of quartz, it can consist of any other mineral or rock fragment as well. Coral sand, for example, consists of limestone fragments.
