#terrasigillata

Developing new surface treatments for terra sigillata on ceramics. I’ve been fascinated with terra sig ever since I first heard of it, and have played around with using it ever since I first started working in ceramics. . I posted before that I wished the surface of my terra sig work was more saturated in color. This isn’t just an issue with terra sig, it’s also an issue with mixing in stains into clay and underglazes. The typical fix to this is to apply a glaze. That works for colored clays and underglazes, but the glaze completely burns out the unique watercolor like quality of terra sig, not to mention the smooth surface texture. . I know people have used borax and soda ash washes to “activate” the surface of clay more, and I played around with that, but I wanted something better, and I believe I’ve found it; and it works well at lower firing temperature too. . In researching the possible ways the borax and soda mix interacts with the clay surface, the common wisdom is that they’re fluxes that will make the surface clay vitrify at a lower temperature. But I suspected that a part of what was might be happening is that the boron was acting as a glass former. So, I wondered if using phosphorus, which can also be a glass former, especially at lower temperatures, might work better. . I can’t prove for sure this thesis is what is happening here, but it gets me the surface results that I’m looking for. These are tests of washes made from Tri-Sodium Phosphate (TSP) and TSP mixed with borax. It’s more than just ceramic, but I wouldn’t call it a glaze. It’s kind of a polish. . #ceramics #terrasigillata #glazechemistry #lowfireceramics https://www.instagram.com/p/CdrivGhjRFl/?igshid=NGJjMDIxMWI=

In the kiln. I learned a lot from my first attempt at carving terrasig. Hopefully I have corrected the mistakes with this one.

I never got around to finishing the drawing because I already knew the image I had in my head would not translate well to clay. Also, this final heart is most reflective of me right now which was difficult to face, I think creating these really helped though. I discovered crows are the worst to draw, and were much easier to make out of clay. Fortunately Paul Revere and Harry the Horse were completed before I left (thanks to everyone at the studio who coordinated and made space for me in various kilns!), but unfortunately I did not have time to photograph them. #heart #anatomy #clay #ceramics #drawing #sketch #pottery #ceramicsofinstagram #pottersofinstagram #terrasigillata https://www.instagram.com/p/B9NugdeAfm9/?igshid=1vroh8sg5nou7

Two of my bowls from long ago. The first is dated 1995 the second is from 1982. Earthenware sagger fired with terra sigillata surface. #throwbackthursday #bowls #terrasigillata #earthenware (at Chamblee, Georgia)
