Saw Mick Hanbury decorating a bowl using Acrylics, he sprayed the bowl black then applied the colours, one drop at a time, and blew the drop in very small, random arcs with a compressor, the resulting effect was a very attractive rose-like flower, he then painted in the stems from the base upwards with a very thin artists brush, the overall effect was very nice and very different, sadly I have no photographs and cannot find one on the web, it is a fairly new technique with him but if you would care to email him I am sure he would be willing to help.
