Topic: Opalescent goblet with enamel flowers and gold butterfly

[glassobsessed]

Thank you everyone, very useful, French it is then. Yes it has a fiery opalescent glow especially in sunshine, there is a tiny hint of that in the photo of the foot but it is faint in this set. The foot does show that glow much more strongly than the body where it is mostly obscured by decoration.

Searching with the term opaline was much more productive than whatever I was trying before! There are several items that appear similar in style with that pale pink painted background so I am happy with French as the consensus:

I think it might be a little earlier than those perhaps.  Although acknowledge the floral painting and vogue for this later in the century.
