This is the top of the colour round bar.
I set up a stainless steel grid system that had 1inch holes over one of my Zircar Molds (any circle containment will do , but this one was only 2 inchs tall, not toooo far to drop for the glass ) and then piled the glass upright ontop of that in a controlled manner. I must admit that it was hard to saw up this piece, but I knew I would have the top and bottom and ALL inbetween so off I went to the saw. I was able to saw in 3 and 1/2 inch sections and then saw sideways through it all. Hope this makes sense
and here is the underside. This was set up with a irri bottom on a primed shelf as well, and then I saw off or grind off the irri when I am ready to use in a piece.
