don't forget to label it hot

We have sample, are you can modification on raw glass tube for make same dimensions and specifications of our sample??

works for quartz too?

hi, thanks for the video, how do you name this cutting tool ? I'd like to buy one but don't know what to look for. Thanks!

Is it possible to make adjustments to a glass tube and manipulate the diameters by heating?

I am going to use this technique to make a glass tube for my computer's water cooling.

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.

@@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.

what if I want to break a small piece off the very end of the rod to make a bunch of rashing rings from one glass tube, can you use pliers to get the torque you need? What kind of a file did you use?

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

You should have a video showing how to bend Pyrex glass tubing. A propane/oxygen torch is needed to do this job.

Mapp works just fine

Yes, but it is flat on the outside of the corner

HELLO CHEM FELLOW CHEM 101'ers!

This looks like something from the 80s-90s

its a good idea to relieve the devitrification on the inside of that bend before flame-annealing to ensure maximum durability preferably with a hand torch, 2 point bridging, and to seal the end so you can even out the wall thickness by inflating a tiny bit, not to mention proper kilning if this would to be ever used. I dont think that this demo is useful at all, providing this info can get someone hurt or even killed.

Not if you're working with borosilicate.

Nice video, but you should have told us what kind of glass you were working with. PYREX, I assume...?

@felixar90

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.
