I’m lost. I used Bermuda green mason stain in my porcelain clay body and it turned dark grey. I fired to cone 6. When I mixed it I used about half pound of stain to 7 pounds of a thick slip once wedged I get about 6 pounds of clay. I mix it with a mixer and then wedge it very well. I’ve never had issues before with any other colors. I used amaco clear glaze on top. I don’t believe it’s the glaze(maybe I’m wrong) because even sections I didn’t glaze are dark grey. Someone please shed some light on this and help me achieve the right color before I lose my mind
