judyfunk Posted November 28, 2023 Report Share Posted November 28, 2023 Hi, All, Recently restored my kiln and want to use commercial underglazes, but my go to was Duncan Concepts and they have been sort of discontinued. My vendor carries Stroke and Coat, which I fear are too translucent. They do not have The Amaco velvets offer Colorobbia underglazes in a wide color range but I can't find out anything about them. Does anyone have experience with this brand? Quote Link to comment Share on other sites More sharing options...
Bill Kielb Posted November 28, 2023 Report Share Posted November 28, 2023 (edited) Amaco yes - good results for me. Colorobia no experience. Stroke and Coat as I recall is a glaze that melts fine at 04 as well as cone 5/6. Not really an underglaze though.

neilestrick Posted November 28, 2023 Report Share Posted November 28, 2023 I would order whatever you want from an online source. I'm a big fan of Speedball underglazes. judyfunk and Rae Reich 2 Quote Link to comment Share on other sites More sharing options...
judyfunk Posted November 29, 2023 Author Report Share Posted November 29, 2023 Yes, can do, thanks; have not tried Speedball! Still curious about Colorobbia, though. Many PaintYourOwn studios buy from Bisque Imports and Colorobbia is what they're now carrying. Quote Link to comment Share on other sites More sharing options...

While I have no favorite brand colors at lowfire temps often can be much more vibrant. Additionally color shifts with various over glazes can be an issue. Just mentioning because paint your pottery generally favor lowfire stuff for energy use and …… bright colors. The only way to know for sure is with testing. A brief search of the web seems to Indicate low firing temperatures for colorobia.

Callie Beller Diesel Posted December 6, 2023 Report Share Posted December 6, 2023 Don’t discount the Stroke and Coat. While they’re technically a glaze, it behaves like an underglaze that happens to go glossy. It’s quite stiff, and if you don’t cover it with a suitable clear at earthenware temps, it can show raised brush lines. They’re smooth at cone 6. I have not found them to be translucent at all. I have a friend who runs a paint your own pottery place, and they use them as underglazes, with a coat of clear over top. They don’t run or blur.
