Frank. Thought I'd come back to this today, when I was less tired.
Thanks for your detailed explanation, but it assumed a level of knowledge which I don't have.

I am familiar with the Cloisonne technique, due to you posting a photo here a while back, so that's a help with getting to know surface decoration. What I'm not sure of however, is what part the gas played...
I'll take a look at your site later, perhaps it's on there. I don't want you to go to the trouble of posting it, if it's already available to me.
