I have a good friend in New Zealand that buys glass and ships it to me so that I can combine and ship to her. Ends up costing her less, and she gets some glass that otherwise sellers would not ship overseas. this is one of her pieces. I told her I would post it here for some thoughts on ID.
Very well executed in a kind of Satin finish glass. It measures about 4.5 inches in diameter and approx 2.25 inches tall. The pontil is done quite nicely. Nailsea was suggested as a possibility, but I know next to nothing about that glass.... so here it is..... looking for some help.
TIA, Craig
