I'm not sure how gold you want (or expect) it to be, this was on a white ^6 stoneware clay, fired in oxidation.
I've also added a link to a pic of the same glaze fired by someone far more experienced than I'll ever be - recipe is also shown on the linked pic below, I altered the recipe as Cornish Stone is not readily available.
Potash Feldspar 40.87 Flint 13.42 China Clay/EPK 6.71
I am ready to test some glazes on the red clay. I just realized that the recipe referenced above is the same one I already mixed up and tried on white stoneware! The photo in the link is gorgeous. I hope it looks nice on the red clay, too. I'm going to try a couple of others, as well. Fingers crossed.
Thanks for the responses. Unfortunately, it will be a while before I can mix my new glazes and do a firing, but when I do, I'll try to record the same kind of temp info and see what it looks like. I wonder if it makes sense to try to do two identical (well, as close as possible) versions of each test tile, and do two glaze firings--one the usual way, and one trying to slow down the cooling phase. Am I over-thinking things?
