HOWEVER.. when you put in under a torch it is then A LIQUID!!! come on Bill, clearly you have never blown glass!!! I have... it twists your view point of what it is and that is what his is talking about here... he works with liquids "like honey" in his hands... those liquids those who work with what he produces works with solids... glass IS a solid at room temp.. HOWEVER.. when you put in under a torch it is then A LIQUID!!!

I was most impressed with the glass springs that were made for high precision scales. Unlike metal, glass springs always return to their initial position unless broken or heated to high temperatures. NEAT! Also, I really want to buy the heart in a jar, but sadly, there is only the paypal option. We don't use paypal in our politically aware household.

At the pharma company where I used to work, when the guy who had been the glassblower retired, a black market basically started up in his stuff because it was so good - the new guy just didn't have the knack - his stoppers didn't seal properly, or the flow rates were uneven. And it's beautiful stuff. These guys are like golddust!

It's an amorphous solid, but it's a solid. It reacts elastically to applied forces and does not deform continuously under shear. They are not crystalline, but that doesn't make them liquids, though they do share many microscopic similarities with them. http://dwb4.unl.edu/Chem/CHEM869A/CHEM869ALinks/www.ualberta.ca/~bderksen/florin.html

I can't imagine the time it takes to develop the right precise "feel" for the glass to get so much control over it.

I'm living presently in Bangkok. A soxhlet extractor costs $400 from Fischer; I got mine here for $25. $15 for the ground glass joints to be imported, $10 for the local glassblower guy to make up the rest. Along with a nice RB flask, it's currently sitting on top of a stereo speaker filled with twinkling Christmas lights. Looks great, is same-same, how am I ever going to explain this to Customs??

This lets you see the hot glass through the glare of the bright yellow sodium ions. Art glass usually is done freehand, while scientific glassblowing often relies on a glass lathe. Scientific glass work generally relies on borosilicate (Pyrex) glass. Borosilicates are less likely to crack when heated in one place, due to their lower coefficient of thermal expansion. Glass artists prefer soda-lime -- it's available in many colors, melts at a lower temperature, and is easier to work by hand.

And this like the artist mentions is due to its crystalline structure, Glass is actually a supercooled liquid. Just a pet peeve if an expert (which he clearly is) sometimes misspeaks and usually it is just to appease an audience, but still never assume the audience doesn't know what is being talked about. I believe Feynman used to get pissed off at this as well....? I believe glass is not actually a solid.
