I see that Andy got you a purple recipe, adding cobalt to a glaze with talc can produce a lavender to purple. 2- 4% Manganese dioxide in a glaze with custer spar and Gerstley Borate will produce a mauve to brownish mauve. The only idea I had on pink is testing some stains, the Matt B glaze in the 10 Tried and True Cone 6 Glaze Recipes looks like a good glaze to start with since stains are being used with it. Happy testing.

Take a look at this article:

http://www.brackers....th_elements.cfm

It covers using lanthanides as colorants. It includes base glazes for cones 8-9 ox, cones 5-6 ox and cones 9-11 celadon type glazes as well as the suggested proportions for each oxide. This includes a nice pink using 8% erbium and a lavender 5.5% neodymium oxide with 1% 6 Tile Kaolin.

I played with these when Ceramics Monthly featured an article about them in the early 2000s and you can get some very interesting and unique effects.

Erbium oxide is roughly $15 per 1/4 lb and Neodymium is roughly $10 per 1/4

Most of than lanthanides can be found at Laguna distributors and I thought there was another company US Chemical or something like that (I haven't had a set up to mix my own glazes in about 5 years) that sold them, but I can't seem to remember the exact name of the company anymore, sorry.
