I do not ordinarily work with exactly these materials. If I had
this problem, I might add a bit of clear glaze to the underglazes.
Even if the fit is not perfect, adding some glaze can still help it
melt more for better adhesion. Perhaps about 1 part of clear glaze
mixed with 3 parts underglaze would be a place to start. Since this
dilutes the color, a second coat of undiluted underglaze may be
needed. The first coat (glue coat) could be quite thin.
