[email protected]Nov 06, 2017 Colorants. Mesh size can make a big difference with colorants. For example, when making a blue celadon, if you use 100-mesh black iron oxide (an old school way of mixing blue celadon with a coarse grind) you might get speckling. This can be corrected by ball milling the colorant in a small amount of the glaze for several hours then adding it to the whole batch
