One of the other things i found at a French "vide grenier" was this Tazza. At least i think it is a Tazza.
It has no marks and no seam. The three sides where the bowl and the foot are joined are slightly different, as well as the three "foots" (don't know the correct word, and it really is one foot)
The bowl is purple and has a few tiny air bubbles.
Some one knows what this exactly is?
Best regards,
Michael
