Yep, Richardson's were often transfers too.
Alissa, did you read in the Mergl book on pg. 179 about transfer prints combined with painting? It talks about Pompeiian red being one of the common "contour" colors. So, if I understand it correctly, the outline/background is done with a transfer, and it's combined with hand-painted details. I don't know, though, I'd like to find out more about the process.
Did you see the Harrach exhibit at the Prague Museum of Decorative Arts that the book came out of? I would have loved to see it, but it had just ended. The pieces borrowed from Passau still hadn't made it back there. And yes, I'm still working with copper. In fact, I've always wanted to combine glass with metal.
