  1. @Callie Beller Diesel Thanks for the black sig recipe! I am very intrigued but don't have a ball mill. Though, the speckling is sounding like something I would like to have in the finish.
  2. @Callie Beller Diesel I am using Georgie's Trail Mix clay. I have no idea of it's contents but description says plastic and forgiving with sand for strength. Midrange stoneware, off-white after firing. I recall reading about the particle size of stains being larger and heavier, would using oxides make a difference? If so, what would yield a good black or dark brown? As a result of my testing additional colors, I found that the peacock and hazelnut brown did very well after firing using my clay body! The colors stayed bright and sheen remained. The black and deep brown went gray as u
  3. I am using a plastic bag and polishing and sometimes with a soft microfiber cloth. I've tried a metal spoon and a smooth rock but those seemed to leave marks, which might be because I'm not burnishing properly. Any other suggestions that I might try? Today, I tried a bright peacock blue mason stain and a chestnut brown with both the clay body I normally use and a ball clay. I got better results with the brighter colors with both terra sig mixes, more like I expected with a satiny sheen when dry with the color still bright. But the black and deep brown both also turned shades of gray
  4. Today I tested a black mason stain with the same clay terra sig 2 ways: one on the same textured sample and another on a greenware, smooth vessel. Both polished up nicely but the textured sample hazed a bit, though not as much as the deep brown. Still waiting on the vessel but I can see a some of it turning where it is drying. I put on as many layers as I needed to not see any of the clay underneath but unfortunately there's a hairline crack in the sig where I assume it maybe dried too quickly with as many layers as I put on (too many too quickly?). I did try a plain one without stain a
  5. Thanks Neil for your feedback. Much appreciated! I've also covered a small, smooth bowl with the deep brown terra sig with 4+ layers and polished it. Same outcome, where it is beautiful and rich until it starts drying. Then turns hazy and gray. I've also tried different ratios of the stain to terra sig with same haziness so I guess it must be the stain or maybe the clay I am using. It's almost like the thin slip is drying over the stain color., if that makes any sense. I will try out different colors, maybe with ball clay, and test them out to see if I can get beautiful results.
  6. Hello there! I very much like terra sigillata and have started to make small batches of my own, using the same clay body that's dried and crushed, water, and sodium silicate as the deflocculant. I let it separate, decant the top layer of water and ladle out the sig. I am adding a mason stain (deep brown) after the preparations. I have applied the colored sig to a piece of greenware (a bowl) and a textured bisqued sample. I apply as many coats as needed to get an adequate layer and then polish with a plastic bag and buff some more with a soft cloth. When finished, it's the most beautiful c
