I plan to venture into the world of 'onglaze' painting. The books I have, go on about all the various oils required to use as a medium. The pottery suppliers I go to, have said that oils are only necessary for the onglaze stains that contain gold, (i.e. purple etc) and sold me a tub of their own milky/watery looking medium. I tried to find out what the medium consisted of but apart from saying it contained some PVA and water, she was very cagey about the other ingredients. Any advice/recipes/web sites for this mysterious concoction. Any supplier is at least a 5 hour round trip from my home, so I do need to make this myself, plus I have to be penny wise and not pound foolish. I would be delighted for any tips on onglazes.
