Hello Alisa,
I see your recipe below is exactly the same as one I have, named Touchtone
Red, and I get a gorgeous iron red with it. (firing cone 7 ox). I guess your
2 substitutions must make the difference. Also, I am using Kingman feldspar.
I have noticed that a few weeks after mixing, it comes out slightly redder,
but that may not happen with your recipe.
Thanks for all your frequent reporting!
