Well, not all good, actually

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.  
Lesson learned.
