How to Cut, Fire Polish & Bend Glass Tubing 

we still have that same table in my HS chemistry Lab, but we put up the new elements with paper pads

wait I lied that is way emptier then the one in our lab. How old is that?!?

@john doe thank you now I know

V file or a file on home science tools they also sell a glass cutter

Amron Aaron np

I'm only here learning how to, to be strait forward. But just in case you're still looking for ideas, I am thinking that for the torque, maybe a perfectly fitted stopper in the end of the tube, with a wooden dowel attached to its inlet? Let us know if you ever got your project together. Good luck.

As an Ex glazier. We used to debuted glass with a stone.( sharpening stone) even thick coarse sandpaper will work. In desperate times I used a diamond file with water! You can buy special stones with a adjustable bevel either side.i hope that helps? Cheers

+uvman707 How about MAPP gas?

onjoFilms Oxygen and propane is needed for borosilicate, I suspect he is either using mapp on lime-glass or propane on flint-glass in this video.

onjoFilms Edit, he is probably using propane on sodium-lime glass

Mapp works just fine

Instablaster.

Probably american pyrex, as he talked about sodium atoms in the glass, so it's soda-lime glass. European pyrex uses the more expensive and better borosilicate glass, which is also harder to bend and needs higher temperature.

@@felixar90 What? Pyrex is Pyrex. If it's borosilicate then it's Pyrex. If it's soda lime then it's soft glass. You need to heat soft glass to very high temperatures because if you try to just work it with it torch like he did, it will literally explode.

@@tigertoxins584 No. Pyrex is a brand name. They got into the business making high quality borosilicate glassware, but like everything else, the brand changed hands multiple times, and they changed the recipe. Depending on the country and date of manufacture, Pyrex brand glassware can be made of simple tempered soda lime glass. en.wikipedia.org/wiki/Pyrex#Composition Notice the different logos. It's like Kit-Kat. In most of the world, Kit-Kat are made by Nestle, but in USA, Kit-Kat are made by Hershey's and are pretty much completely different. The Slo-Mo Guys have videos where they break both types of pyrex. The borosilicate cracks into large deadly shards of lethal ultra sharpness of death, while the tempered soda-lime insta-shatter into tiny cubes.

@@felixar90 Borosilicate glass has sodium in it as well, and has an identical flame color as soda lime glass when it releases sodium ions. You have to step up to spectral emissions analysis before you can differentiate the two.

Not if you're working with borosilicate.

Do u think i could make a downstem for my bong with that

@@thedashgamer8146 Haha that's exactly why I watched this! I'm trying to make a diy bong

That would be sick. I've got acrylic tubes in my computer. My concern with glass is that with the way the fittings tighten into the tubes could crack the glass easily. With my build, I for sure would have broken tubes trying to install them. The ability to have the acrylic tubes flex a little helped with getting into some awkward places where a more brittle tube probably would have broken. I actually had to heat one the the tubes while it was partially in the case. Cool idea though. You could make an awesome custom reservoir with lab equipment or by blowing glass.

@@danlev6927 You can buy the glass tube from www.mayhems.net , it's a Borosilicate Glass dedicate to PC's water cooling. Do not use chemical purpose glass tube or aquarium purpose glass tube.

@@p72910 Why not? What's the reason you shouldn't use laboratory glass tubing for watercooling? I mean other than risking it containing any corrosive chemicals if not cleaned properly lol.
