Don’t feel like the Lone Ranger. Almost everyone who does cabs runs into this.
Are you grinding the cabs before the final firing and getting gray at that point? If you are, that is the main contributor to the problem. I use progressive grits for grinding, being sure to keep the piees in water between each grinding. I use 180, then 400 then 600. At the end I still use a homemade brew of devit agent (see my tutorial on that). Do not have the problem any more.
I use thinfire and do feel that is a contributing agent, but you can ignore that if you do the better grinding and devit agent.
