  3. 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?
  4. 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!
