Coincidentally, at a small antiques fair today, i saw another vase, same shape and size (i think)
it was mottled green all over, from top to bottom, and on the top it had a metal cap! Not a mesh top,
but a domed solid cap, i thought it may have contained ashes

but nothing, it was loose, but i think
original, i would presume to encourage a decorative use for the vase, without using it for flowers.
Dealer wanted £45 , bit steep for me today.
sorry, no pics .
