This was a piece that Ted let me have to embellish. I did several colors of underglaze that blended into each other, with black shapes painted over the color.
I expected bright and beautiful. What I got was dark and muddy.
My guess is that the clear glaze was the factor. Evidently in using a clear glaze in a high-fire, it should be one without zinc in it, because that can affect the colors in the final outcome. It did. Oh well, back to the drawing board.
