Hiya SueC & josordoni,
I've never had any Heron Glass before.I had a wee look at their site though SueC and I'm not sure I'm looking at the right place.. heronglass.com?
My pot is smooth on the inside with the decorative application on the outside...Is Heron Glass like this?

Many thanks for your help with my daft questions,
Elaine
P.S. Love those Heron Whirlygig Goblets!
