Lori,
Although I'm relatively new here to Clayart, I think I can help you in this area. This ties in with the "where are the results thread" too. A few years ago I started experimenting with the cranberry/pink/purple mason stains and like you, couldn't get the colors to develop for nothing. Following suggestions from generous Clayart members, I found that a certain amount of calcium is needed in the slip/sig base to develop cranberry/pink/purple stains. I add about 10% whiting to my slip base and have had great results. Wollastonite works too. I then discovered that certain clear glazes will wash out that color, so I've gone to a clear base that has additional calcium in it. I currently have a beautiful clear base and the mason stain colors to boot. I tested a LOT of test tiles, coated them with the slip, bisqued, then dipped only half in the clear glaze I wanted tested. The results will show the slip color by itself, with the bottom half of the tester in the clear glaze.
There doesn't seem to be the same difficulty of developing colors in the brown, black or blue/green range, only the pinks/purples, etc. A few especially nice colors are the Mason Stain Pink 6000, Blackberry 6381, and Purple 6387. Try 10-20% stain, maybe up to 30%, depending on how dark you want it. These stains work nicely added to a clear base as well, as long as you have calcium source in the base. Hope this helps you ... let us know.

I have used Crimson Mason Stain ( about 10%) for a cranberry using
Mizumo Glaze. I apply it like overglaze decoration in Majolica but it
is cone 6.
Many of the Mason stains give great color this way and the Mizumo Glaze
(actually cone 5) The recipe is from CM and the book on electric kilns.
