What can We do with this?

Pyrex glass tube, 10" long......1/4" wall.......1.75" I.D.

You could bake a small loaf of bread. "When done, remove loaf." ha I suppose you could use it as a snorkel for a jam jar or augmenter of some sort, might be neat in the dark. I have some clear SiO2 tubing as well. I just haven't gotten around to toying with it as well. One of these days ...

I was thinking of glueing a head cap one or two inches should do. A leanear fashion and taper on the exhost pipe. Would be good!...

Put some armer between me and it and fireing it up!!!


Damm ,,,I sound like Elkablooey !!!!!!

actually, that'd be pretty neat, a PJ made of glass... then you get the full effect of the combustion!

PS: what's Pyrex rated to anyways?

Here's Pyrex and a lot of other melting points such as copper, quartz, titanium, chromium, nickel, all in a nice melting point order by temperature in both C and F. Just scroll down the page.

Here's a tidbit on quartz vs. borosilicate glass, aka (Pyrex).

"One of the most important properties of fused quartz is its extremely low coefficient of expansion: 5.5 x 10-7 mm °C (20-320oC). Its coefficient is 1/34 that of copper and only 1/7 of borosilicate glass. This makes the material particularly useful for optical flats, mirrors, furnace windows and critical optical applications which require minimum sensitivity to thermal changes."
"A related property is its unusually high thermal shock resistance. For example, thin sections can be heated rapidly to above 1500 °C and then plunged into water without cracking."

Nice. Spent a while on that one, thanks.

Man! There's a pile of info on that site
