This is my first posting but I have a vase whose body is almost the same but without the gold flecks and a very free flowing green glaze running down it. It feels pitted on the inside and smooth on the outside and from the outside you cannot feel a raised area over the green, although it seems to have been applied over the body just smooth glass.
The rim of the base is not the same as yours and the foot has been ground down. I bought it a year ago from somebody who was clearing their grandmother's effects, and thought that her grandmother had had it for 60 or 70 years and that she purchased it abroad - not England and not Germany but wasn't sure exactly where!
When you examine it under a magnifying glass it is hard to tell whether the internal structure is microscopic bubbles or pitted. This effect runs in soft veins all through it leaving a few patches clear. The nearest I can get to the effect is almost like that of a skeleton leaf. It looks from a little way away or in photos to be very fragile but is actuallyvery sturdy. Interestingly, mine has the remains of a label, but only the central part remains. I have looked at lots of pictures of murano labels and cannot find anything similar. It appears to be a black or sepia coloured ground with a central oval - upright - containing a shape - perhaps a jug or ewer in cream within the oval - Traces of writing remain - at the bottom which could read ? HAND in capitals.
The vase is heavy - very striking and quite large. Approximately 8" high and 5" wide and 3 - 4" at base and rim. T
Photography is not my strength but if my description in any way matches yours I will make an attempt. Please let me know if our items share any of the characteristics I have described or could anyone suggest a label which matches the description? Thanks
