Pot-Melt - using Ceramic Dams

In the past - I've been asked about "something about using a flowerpot to melt glass ... . " This is the technique.

The calculation he gives for quantity is really interesting, and the end result would look totally amazing sliced into thin layers and turned into pendants, or wrapped around a bead like an encasement layer. Or even bent into bracelets ...

If you are using ends of rods, you can toss them in, or arrange them standing upright, sorted by colour.

Having a tall enough kiln is really the biggest issue for most of us.

And in other glassy news ... 2 D Glass

And in other glassy news - the thinnest sheet of glass ever made - by accident, of course - was photographed to reveal the arrangement of the atoms in the glass. The glass sheet is only one molecule thick - or about as thick as a plastic grocery bag. ;-)

Science still doesn't understand glass completely.

Maybe someone will invent transparent aluminum ... ?

Room temperature glass is not a liquid

I've said this before. Glass at room temperature is a solid. It shares some interesting characteristics with fluids, but it's a solid. It is not slowly flowing and that is absolutely not why old windows are thicker at the bottom.

It's more solid than lead.
