For one of my pieces, I used an underglaze black pencil for outlines, and it turned out too light. I'm thinking about using an underglaze pen instead over these areas and firing it again. The directions on the label say to fire the underglaze pen to 06.
What do you all think? Are the outlined shapes too fuzzy, or do they need more definition?
Should I refire at this temp again? Last time I did a refire at Cone 06, some of the underglaze flaked away and it looked terrible!
Wondering if I should refire at Cone 05.....
Any suggestions would be great.
