Hello,

I have come across and old material in storage labeled Setit-a. I have never heard of this material before nor have I seen it in any recipes. I cannot find any information on DigitalFire or Glazy. Any information on this mystery would be helpful.

Mumblebee-

A quick internet search led me to the following:

https://www.google.com/patents/US3867157

 

I'm inclined to think that it refers to China painting and enameling on porcelain. Very low fire stuff. If it came with a bunch of other stuff (i.e.: used kiln, other bottles or vials of powder, etc) I would almost guarantee that you got it from a china painter. Are you the person who also asked about French Paste? If so, that is probably a compound that is mixed with China paints for raised designs, often now called Sculpture Paste, modeling paste.

If you're not into China painting, you might as well scrap it. There's information out there, but a lot of it is very old (still useable), but hard to find. You might try messaging Paul Lewing on this forum. He's the author of "China Paint & Overglaze".

Hope this helps.

Regards,

Fred Sweet

What Sputty said. I've got some I bought at SPS years ago. It works as both a glaze suspender plus hardener. Only need a tiny bit, like 0 point 25% up to about 0 point 5%. It's brilliant stuff, works really well for glazes that settle like a stone and/or powdery ones. It works like Veegum T.

Setit 'A' is (apparently), a colloidal glaze suspending agent. Think bentonite.

It's also mentioned here, in the context of glaze suspenders:

Thank you! This was very Helpful!
