I have a very large conical bottle in the same design.
Charlie Meaker did train at IoWSG for a while, I assume that was where he learned how to work with silver foil, I don't know where it was he made these though.
He ended up being the director of a large Scandanavian glass company, working outside the uk, but sadly, he is no longer with us. He died not long ago.
The blue in these pieces is not one that was used at IoWSG.
I do like these pieces. Bold and early British Studio glass, by a significant maker.
(It's fun finding stuff you've forgotten about, and seeing it with new eyes, isn't it?
