when i was a chemistry grad student in the '80s, i loved glass blowing at the bench. simple stuff; ampules, cold traps, in situ vac line mods, side arms, etc. i would love to return to it at a higher level as a retirement job. any advice?
Kevin Teaford - the one time I worked with glass in chem 101 I burned the dren out of myself (hot glass looks just like cold glass)... my lab partner did the rest of our glassworks for the year (I still have a scar)... still really wild seeing glass on a lathe !!
what model torch is the small needle flame one you were using for most of the video? it looks like a great little lathe torch (not the nationals - although very cool quartz tips)
Good question, once I take it out of the late, I put it into the annealing oven for 30 minutes at 565 Celsius. This process will relieve all this stress that I created while I worked on it.
FYI, Manually is not the only way, just a way. The reason for the video, was to show how to the job with no card board supports and come out with a completely straight center tube. Can you do that Manually???? No you can't.
Wow. Great videos by a master. Cool to see how the stuff I use is made. No wonder its so expensive. Could sure use one of those bump traps.
Excellent work
you're pretty damn good dude! wish i had someone like you teaching me.
+Dustin Bodendorfer thanks! Glad you enjoyed.
Thanks Dustin!
Wonderful work brother
Great informative video. Thanks for sharing!
Thanks!
This is a great simple way well done i see ppl do them on the bench ....not me lathe man,

Really interesting process. I wish I was allowed to use the lathe in my school's glass blowing shop
Your school had a labglass shop wow we didn't even have decent flasks and most condensers were stolen
there is no reason to build such a small piece on the lathe
@@gabrielfelix1481 there are numerous reason!
Audacity. Reduce noise. Amazing work regardless.
Would it be possible to weld a piece of glass tube to the side of a mason jar to convert it into a filtering flask? Like a DIY project.
sure, but be aware that you won't be able to do any vacuum filtration with a mason jar
Found my dream job

jwdshiff Glad you like the torches. If you are interested, I just posted how to make the quartz tips.
thanks
How do you finish these up? Do you anneal these in an oven or is there a special way to do it?

any scientific glass blowing school in usa or Canada??
+Jaskaran Singh Not that I know of..try to find glass company and learn from the bottom up.
Your ground joints will stop popping off if you use graphite tape!
Я вручную это делаю.
