We were at the Bay Area Maker Faire this last weekend in San Mateo, CA. Michael Dickinson from Marin County was demonstrating his glass blowing skills. He made a throw-away sea shell that was so detailed, so gorgeously colored and so life-like that it could fool a person. He made the piece for practice and demo at the event. He doesn't even bother to anneal the piece, so it will probably break after a few hours or days.
His regular art glass is magnificent.
You can see him working on a seashell at 1:50 in this Maker Faire 2016 Glass Demonstration video.
Lastly, here is a flower he made...
I was there Saturday, and was amazed by the beauty of the items in his tent - truly an artist!
Too bad his stuff is too appropriately expensive (and I don't host fancy shindigs where fashionable people drink alcohol) to justify buying some of his work.
