The top glass anneals essentially one sided, but the bottom glass cools down one side through the shelf the other side trough the insulating air and top sheet. That is a complicated situation asking for ver...

Re: quick cutting tool from Doug Randall's video

That looks like the Glastar strip/circle cutter set up for cutting strips used to cut repetetive lengths from a strip cut earlier. http://www.glastar.com/catalog/reference/scc_instructions.cfm Another tool to produce the same results would be the Morton portable glass shop set up on the Morton surf...

P.s.

I add some CMC into kilnwash, too.
It gives harder surface that I can sand smooth.

Like Bert, I have used CMC. For those who are afraid of chemical terms, I can tell it is the stuff that makes jam to a jelly and not juice. I had a class at Päivi Kekäläinen ( for Englsh speaking friends Paevi Kekaelaeinen). She used starch as a binder in thin pate de verre. CMC is very close to ...

Thanks Marchmyres,

"Quartz: a naturally occurring crystalline form of silica (SiO2) and one of the most abundant minerals in the earths crust."

Just checked it is still missing in the next edition! (Coming soon)

pronounciation

I would appreciate very much, if someon
wants to include a pronounciation column in the dictionary.

Most of my English is from reading and net,
I have not the slightest idea how words are
pronounced.

Ask Siw about Oslo, she is Norvegian and lives quite near to Oslo. Frogner park is great, but don't miss Munch museum. As a sculptor, I love his litographs. ...

If you are really desperate,
you can make a plaster/silica mold around your piece.
Don't forget a splash layer, or pain the piece first with kilnwash.

Then you firepolish it inside the new mould.
If lucky you get a nice inner surface and matte
outer surface.
