Quote .............. "without room for root development it is not a bulb vase." Ivo's comments are correct - I was so carried away with thinking this is a good find, that I overlooked completely the fact that here the body reduces in diameter, whereas true bulb vases increase in diameter - so sadly then unlikely to be a bulb vase. It was just that the pan-top shape looked ideal in which a hyacinth bulb might sit - a shape that is so obvious in appearance that as part of the design it must imply some particular use/purpose?
Regret to say my 1981 copy of Phelps Warren long since gone - Mike, are you thinking of the Irish vesica cut pattern? - vaguely similar compared to this repeat sort of elongated ovals - isn't a merese something that joins a bowl and stem?:-) I'm wrong in saying this is a Van Dyke Rim - it's vaguely similar with pointy bits that stick up, but couldn't think of the correct name for this one - perhaps it doesn't have a correct name.
I've also parted with Patricia's bulb vase book - is it still available anyone know?
I don't get the feeling that this piece is old - as in c. 1820 - sweetmeats this age would have acquired much wear, I would have thought, and that's not apparent here - plus I'm not normally lucky enough to find early C19 glass undamaged. Also, possibly, I'm thinking that this piece is a tad too tall (alliteration:-)) for a sweetmeat. ??
So, current status is that use and age remain unknown.
P.S. yes, Mike, I have a few pieces that you will not have seen - will try to post in the coming days - presently too hot to spend much time at the pc.
