Steven, I see you go on to the site, though I'm sure I will never have to moderate you! such a nice man!
Paul, the last 2 pics are a bowl made from a 1/2 tin of casting resin that a teacher left the top off.
No hardener was added, but I found it a year later, solid as a rock! Cut it out of the tin and turned it!
The outside was textured with a burr in the Dremel
Rather nice and very original, Neil. Pray tell, what is the Institute forum?
