sandra b Posted November 25, 2010 Report Share Posted November 25, 2010 I made some tests by brushing 3110, 3124 and 3134. I used 1 tsp in a cup of water. The solution showed a lot of brush marks; and after firing at cone 5, it showed more sheen where it was more thickly applied. I made another test spraying frit 3124, it showed some sheen after firing at cone 5, but not the satiny finish I was hoping for. Next test was spraying Gerstley/Gillespie borate solution using 1 tsp in about 3 cups of water. I fired again at cone 5, which is the lowest standard temperature for glazing at the community college where I fire my pieces. The result was a very dry harsh finish. My intention is to find a finish that adds a slight flux to the stained and underglazes I use to finish my pieces, something that doesn't look neither too dry or too shiny. I can fire at other temps if I can gather enough work to fill a small kiln. I would appreciate some ideas in how to apply these or other materials to obtain that satiny, smooth finish that I dream of. Thanks and Happy Thanksgiving!

Marcia Selsor Posted November 26, 2010 Report Share Posted November 26, 2010 Why don't you use a satin glaze for your base with a brush work additive like a cmc mix? Are you brushing on top of a glaze?Are you simply trying to cover the underglazes for a finish only in certain areas? Marcia Link to comment Share on other sites More sharing options...
sandra b Posted November 27, 2010 Author Report Share Posted November 27, 2010 Thanks, Marcia. A while ago I made some tests with a satin glaze under and on top of stains and commercial underglazes. I liked it best with the color on top of the glaze . The finish was really nice, but some of the underglazes and stains peeled off. I have not tried it using a commercial glaze yet. It's on my list. I like color and the depth you achieve by layering underglazes and the possibility of multiple firings, having a glaze somewhat limits the process. I read of a Gerstley Borate washes, frit finishes and/or mixing some fluxes to commercial underglazes, but with my tests I have not obtained good results so far. Any other ideas?

Marcia Selsor Posted November 27, 2010 Report Share Posted November 27, 2010 I guess much depends on the clay. What are you using for a white base? White clay? White Slip? If your underglaze is peeling off , is that where the glaze was on top? Reaaly not clear. Can you post a jpg in the gallery? marcia Link to comment Share on other sites More sharing options...
Deb Evans Posted December 6, 2010 Report Share Posted December 6, 2010 If you go for a satin glaze and just want a surface - thin the stuff down a lot so that it just gives a white veil to the stains - Link to comment Share on other sites More sharing options...

Marcia Selsor Posted December 12, 2010 Report Share Posted December 12, 2010 These look like you are getting what you were after. Great! Good luck with getting the results on your larger pieces. Marcia Link to comment Share on other sites More sharing options...
Deb Evans Posted December 12, 2010 Report Share Posted December 12, 2010 your experiments look great! remember that some glazes and stains react to red clay body, looks like it's more stable w/ the gray stoneware. happy holidays. Link to comment Share on other sites More sharing options...

Austyn Taylor Posted November 23, 2020 Report Share Posted November 23, 2020 Hi are there! Can you re-upload the images? The links are broken! Did you ever get a good frit 3124 to underglaze ratio for satin? Thank you Link to comment Share on other sites More sharing options...
