terra sig is best when the specific gravity is about 1.15. useful range is 1.1 1.2. specific gravity is measured by weighing out 100 grams of water, marking the volume, and weighing the same volume of the sig. divide the weight of the sig by 100. If too thin evaporate. If too thick allow to settle longer.
fifth, if you add a colorant to terra sig like a mason stain, its important to pass the sig and colorant through a 100 mesh screen. better yet, put it through a ball mill before using since the stain is so much coarser than the sig. sixth, he made some interesting observations about
clayart thread grinding and terra sig normally, these settle out fairly quickly, but not if you ball mill the mix first. these non-clay particles will reduce quality of the resulting terra sig. deg that is an interesting theory, and certainly trust petes judgement, but with some coarse clays, the only way you will get a terra sig is to ball mill

vince pitelka states that after the initial mix a ball clay, terra sig should have a specific gravity of 1.15. other clays like redart, should have an SG of 1.20. In fact, he recommends adding water to the clay powder bit by bit and checking the specific gravity at intervals.
on ball-milling. preparing the deflocculant the secret of refining a proper terra sigillata is to settle out all but the very finest particles. deflocculant is a chemical additive that causes particles in aqueous suspension to repel one another, and it is a critical part of the terra sig process. only a
terra sigillata literally means earth seal; is a slip containing very fine particles. It is created by a process of separation. We grind specially selected clays using a ball mill and water until the particles are extremely small. deflocculant is added and the mixture is allowed to settle for up to hours. the fluid left on top after settling is the terra sigillata
