Glaswork

While waiting actual glassblowers...
1. Posting a pic of the actual broken part would serve you better than some random pic.
2. You could list your tools, since it's pretty likely that you are lacking something important (and expensive).
3. In addition to trying to fix it by yourself and buying a new thing, there's the option of paying a professional to fix it.

you need to warm the tube, to bring it up to temperature, so then you can cut it with a torch. post pictures..


I am a beginner lampworker, I can help alittle

The broken part

you need to warm both the apparatus and the piece you want to attach, than you need to take a small torch, heat the broken piece till it is about red hot, and mash it together.

then heat them both with the torch together

Do I only need to heat the part of the aparatus where I want to fix it or the whole thing?

>>1028041
Since it's snapped off so cleanly, you might also want to consider an epoxy kludge or something similar which does not involve melting glass.

Just in case you didn't notice: that cylindrical part is a glass stopcock with a ground glass joint. How is he going to avoid fucking it / what tools he needs to unfuck it?

I tryed with an UV activated glue and also silicone. But as soon as solvent goes trough the glue gets disolved.

Good question, thanks bro and I'm good at fucking things

that's a nice drug manufacturing aparatus you got there. is it a felony where you live to own one without a license?

since that's a barbed connection, I assume you can connect something like a nitrile tube to it.

you can buy whatever solvent resistant rubber hose material and form a sort of rubber condom around the neck with a tube joined to it and use hose clamps to fix it in place.

nitrile is resistant to solvents like uhh ethanol and xylene. nylon is another choice. they make fuel lines out of the stuff. protip:it's hotglue. typically these things sit in an ice bath so i assume you can keep the temperatures down. just match the gasket material with the solvents you want to use.

Its free available here, I've it many years now

All your ideas would have been great. Should have try that first....But .... too late. I fucked it up... will have to buy a new condenser... fuck fuck

You can't fix it unless you can control the rate it is both heated and cooled at.

Borosilicate glasses melt at a lower temp than quartz if i recall. Id suggest an oven for preheating, then a torch for melting and fusing. Not sure about cooling procedure but I'd guess that you will want it to cool at >>1028336 a "reasonable" rate.

We wear welding tint glasses when we do quartz melting because the molten quartz is extremely bright and gives off a lot of UV light. I would look into this and be prepared; also its never a bad idea to keep a bucket of lime or sand nearby in case you have to get a sandbox margarita party going real quik

If you just destroyed the stopcock, you still have that "pay a professional" option left.

>>1028484
I first destroyed the stopcock and whike trying to fix it destroyed the whole upper part.... big cracks. I guess I heated to quick... I throw it away and buy a new one.... and I'll keep my fucking fingers off molten glass in future

Check manufacturers like 3M for chemical resistant adhesives.
