Having read that T.Sig. can be made from clay other than ball clay, I experimented with several different stoneware clays & kaolin and they all worked but the yield was greater with ball clay. However, the original T Sig. was made by the Romans as found in Samian ware and they used only earthenware clay, so I also tried that. Unlike stoneware clay, earthenware clay did not separate into three distinct layers. In fact, there was no observable separation at all. Instead, I obtained a colloidal slip with a specific gravity hardly any different from tap water, at 1.02. But it shone without having to be polished! And the shine persisted on a test piece fired to 1,000ºC. I find that quite interesting!

I didn't actually go looking for Terra Sig recipes for when I heard the following, it just happened to be in the background info on ancient pottery I was watching, but it was said (internet scholar, take it for whatever that might be worth) that the Romans repeated this process several times til they only had a super thin layer to work with. Sounds like a lot of waiting and recycling to me! As I happen to have a science-sized unit for doing other processes, if/when I get around to trying this, I might throw my batch through a sonication unit and see if there's any net difference. Not that you can't do you, but I find it handy to have the extra large syringes like you find for veterinary work (I just get the biggest ones I can find in a 5 pack for the most decent price) for pulling separation layers as some of the things I use include very concentrated sulphuric acid; not exactly mouth-friendly for siphoning. 😁 Usually you can snag 100ml 5 or 10 packs for $6-14, market price varying as it goes. Get the ones without the needles and just chop the attachment points for ease of pulling a larger/heavier volume.

Hi from South Africa, thank you for your detailed "Sig" making video. I followed, more or less, your recipe using dried bits and pieces of self dug clay and commercial clay. I ended with a specific gravity of 1.05. I think because the clay has more bigger particles that ball clay which I don't have. Can I leave it out in a bowl to evaporate? Would that increase the SG? Would appreciate your comment. Many thanks for your informative videos. Ute

@deMibPottery

Жыл бұрын

Tera Sigilata can be tricky. You have to find a recipe and fire schedule that works with your clay body. It can flake off if it's not right. The higher you bisque fire the less shiny it will be - but also less likely to flake. I only use Tera Sigilata on pots that will not get any glaze - so pitfire, naked raku, horse hair raku etc. Glazes generally do not stick very well on a high shine surface with Tera Sigilata. But you can also get almost the same shine by burnishing your pots. And then there is nothing to flake of. Its just a lot of work :-)

@katiakatiakat

Do you burnish greenware and then bisque it? Does it loose the shine after the bisque or glaze fire (if I was glazing the inside)?

Hi Mikkel, after firing do you polish your pots with wax to regain the shine? I usually use a non-toxic type of wax made from bee's wax, but I was wondering if there are alternatives that have less of an effect on the colour of the terra sigillata.
