I'll try to post the picture before Christmas....it is a very beautiful swan white with red beak and eyes. The reason I am in doubt about it being Marcolin Ronneby is because it was so cheap, and there appear to be a lot of black grit like inclusions in the glass. I will try to make those aparrent in the pictures for you.
The reason we tend to say Marcolin or Ronneby (and it could well have been me who said that in a previous thread), is because Marcolin did, I believe, for a time, operate in Sardinia, and I thought that at that time there was no connection with Ronneby, who I have always thought to be Swedish Konstglas.......but I love to learn more about glass, so even if you have given the answer before, I would really appreciate you clarifying it again....when you have the time.
Many thanks again Ingela,
