C10 R. SODA/SALT TEST TILES
These are just some of the tests that I made prior to delving into soda/salt firing. Some of these slips and glazes were tested on several bodies but for the most part, I will probably only post one version of a particular glaze or slip. If you want a closer look you can just copy and past the photo into Paint Shop pro or a similar program and magnify it to get a better look at the tiles. (I believe you can still download a free trial copy of it from the web).
GROUP 1
Top row left to right, first tile on left is #4053 on Windsor porcelain. It's a flashing slip to apply to bisque. Apply these flashing slips on the quite thin side.
