To demonstrate and learn a little about simple casting we made “pyramid shaped paper weights.
we were very lucky to have setup for us the mold lined with kiln paper, and glass cut into triangles and resting in mold.
we then filled the mold with bits n pieces of glass, coloured clear and dichroic. I continued my blue, green theme with litle pieces of dichro. we filled to a bit over the top and then laid a glass square over for the base.

To make the edges nice and sharp we used the flat lap grinder with finer and finer diamond grit ending with a polishing wheel.
till our pyramids were smooth and shiny with “sharp” corners and tip!
unfortunately the dichroic does not show very well but u can get the idea. You can also see the small bubbles .
One of the others filled their pyramid with frit, this created amazing tiny bubbles.
