the Broken Glass Chandelier

This is the light shade I made for the light outside the bedroom door.

On a cylinder of metal screening, I've hung pieces of broken glass that have been melted together. The glass chunks are attached to earring hooks, so they can be removed and worn as earrings. Or they can be re-arranged if you want the light to look different.

I've discovered that it is easy to melt glass with a blow torch and make clumps of different colours. However, glass that has been melted together is awfully fragile. I expect that within a few months, half of these chunks will have to be remelted.

Another thing I've discovered is that a 1-inch thick piece of rock is not thick enough to insulate your table-top from burning through if you are heating glass with a blow torch on top of the rock.

A 3-inch thick brick is thick enough.

is it possible that:
1. rocks get hot and burn your table when they absorb the heat; and
2. bricks are made to absorb heat in a good way? (isn't that why they insulate fire places?).

you're the brilliant MIT/creative/practical guy, you tell me!

I suspect that a brick might be better at insulating than a granite-like rock because bricks have larger granules and tiny air pockets.

This would make a brick worse at absorbing heat, and better at reflecting it. So maybe an inch-thick brick would have protected the table better than the rock.

aha! i knew absorbtion was the wrong choice of word!
