Hello fron NC USA and thanks for your video. Re recipe, did you say cow dung? Very interesting process, I am a beginning potter, just bought my wheel, am a bit intimidated by all the health issues involved w/ this craft. I was surfing scraffito and t sig and thus landed on your doorstep, am very interested in learning older, safer, organic methods. BTW, would that be fresh or dried or ???? Thanks everso, Elizabeth
@monalisasmoustache Sorry, not cow dung calgon! Water softener powder for the washing machine! I'm pleased you left feedback, you would have had a terrible time trying to use dung! As to health issues: clean up and mop regularly and wear a mask when handling powders (oxides, glaze etc.). Mark.
@brookfieldpottery Hilarious! Between your charming British accent and the lowered pitch when you said calgon, I thought.... too funny. How in the world did you come up with calgon? Don't most recipes call for toxic or respiratory unfriendlies? How does the calgon work actually, as a binder? Thanks again, e.
@monalisasmoustache Elizabeth I found calgon mentioned in an article online. There wasn't a lot of info but I thought I would give it a try. It contains some of the same ingredients as the more expensive t.sig recipes call for. Basically it acts as a suspension agent holding the lighter particles in suspension while the heavier sink to the bottom. All I know is that it works very well and I'm still using my first batch, so it keeps well too. Mark.
@brookfieldpottery --calgon is a deflocculant, like soda ash or sodium silicate. it causes unlike particles to repel one another, hence terra sigillata (add a deflocculant to a liquid clay suspension, and the particles in that suspension segregate, leaving, after 2-3 days of rest, distinctly visible layers. extracting the middle layer and disposing of the top and bottom garbage layers gives you terra sig.)
Calgon used to be SODIUM HEXAMETAPHOSPHATE with a perfume additive. It was reformulated about 10 years ago and no longer works to make terra sigillata but you can purchase the sodium hexametaphosphate from certain chemical houses or directly from me - BHClaysmith@gmail.com
I know it sounds crazy, but in my studio we always use plastic bags (either dry cleaning bags which work amazingly well, or plastic shopping bags) to do the buffing step. You get a really, really fine finish with a plastic bag.
Although I didn't film it, I did try buffing with a carrier bag. It didn't work on this pot but may on a smoother surface. I hadn't made this pot for T.Sig so the surface was rough.
Thank you for your comment though, it's a good point. I had read an article, before making the T.Sig, about a Turkish pottery and they had used carrier bags too.
Thanks Dan. I'm a bit freaked out with the idea that I could teach you anything, but I guess it just goes to show what a huge subject pottery is. I should point out that T.Sig. doesn't have to be used with terracotta. You can make it with any clay. You'll find a vid. in my favourites illustrating this.
I don't know. Logic would suggest that if you use the same stoneware clay to make the sig as you use to throw with it should work the same (shouldn't it?). After all basically t.sig is just tiny particles of clay which are smoothed into the surface of the pot.
You'll just have to try it and see Lynn. Just mix up a small amount first, in a glass.
Thank you so much for sharing this. I have been meaning to try this for years, so after years of burnishing you finally pushed me into giving it a go! With just some slop from my wheel and a Calgon tablet! I'm applying it now, can't believe it is so quick!!!!!!
I'm really chuffed that you found it useful. I discovered this idea while browsing the web. It was a bit more involved than this, but I realised after searching dozens of recipes that it must be simpler than people think. The Romans and Greeks didn't have the chemicals laying around that appear in most recipes and they produced the best t.sig. pots ever. It makes me wonder what their recipe was?
However it's pronounced, keep up the investigations, I tried recently using the regular Ivory Stoneware i use and some Cobalt oxide to create some Ter Sig. I'm interested to see how these fire...
btw I love you animal additions... the frogs, lizards and bears... AMAZING!
My guess on pronunciation, seems the g is hard before certain vowels, a, o, u, would be my guess, and soft - j - before i and e, just like in other languages, English included, as with the letter C.
Thank you John, that makes a lot of sense. With my groggy clay building up the coats first should make all the difference. That's the problem when you read about these techniques, you really need to talk to someone who's done it before. Nothing counts as much as experience.
You may well be right. I based my pronunciation on reading about the subject. I have only found one vid. and in that it is called terra sig so not much help. In the dictionary it is transliterated with a dz as in jar (I've just looked it up!).
Thanks for your feedback. If you find out more let me know.

Cheers,I think I'll give this a try as I make a fair bit of Terracotta and it'd be interesting to give some of them a bit of a different finish.

Well,you did,and I'm glad I found this new technique. I mixed up some terracotta T.sig and have put some on a stoneware apple I made.
Stoneware Apple you ask ? I think I did a video of it.LOL.
It looks pretty shiny and a nice colour and went into the kiln today.
So I can't wait to see the result.
If it turns out well It'll be a real result,free "Glaze"
Cheers,Dan.

But it doesn't stay glossy if fired higher so earthenware it is, correct? And at cone 6 I'd be wasting my time, I wonder?

Thank you for your feedback. Pleased you like the animal pots, planning to do some more this year, after I've got started and built up some stock.
I would be interested to see how your pots come out of the kiln. Perhaps you could post a vid or slide show? Let me know if you do.

Thanks Steve, it's good to be back in the workshop again, doing something constructive rather than just tidying etc.
