Hi everyone! I'm fairly new to glazing pottery, and have just unloaded a kiln full of pieces I had painted with underglaze, and applied a clear glaze over. Some pieces had been bisque fired with the underglaze already painted, and others were painted onto bisqueware, but all seem to have the same problem of the glaze avoiding areas where the underglaze is. In some places it has caused the underglaze to chip off, but mostly it's just all very rough feeling and patchy looking. There are a few pieces where the rough patches are a bit annoying but not too bad, but the majority have deemed the pieces unusable :-( I used the Amaco velvet underglazes, and a clear glaze from Scarva. The glaze required the kiln to be fired to a pretty high temperature - cone 1 at about 1137 celsius - so I'm wondering if this is the issue or if I've done something else wrong. I'm looking into finding a different lower firing clear glaze but am worried the same might happen again - and I would rather not attempt making my own glazes as I'm not experienced enough - so any recommendations would be much appreciated! I'll try to attach some photos to explain better what I'm talking about (might have to be in another post). Thanks! Amber :-)

Can I turn a clear commercial brushing glaze into a dipping glaze?? I have the Duncan clear low fire brushing glaze.
