I have always loved the soft, subtle colors on Martha Grover's porcelain pottery. Since she fires at cone 11, I did not even think of using her glazes. You can go to her website where she has converted her glazes to cone 6 for electric firing. She uses a Gawk Clear and commercial colorants. She also uses an Opaque White with colorants. Martha's engobe recipe is also included. www.MarthaHGrover.com
