Making Scientific Glassware


I'm going to try and get more posts on here on how to make your own glassware and glassblowing in general. I hope others will also post their progress and insights. It's a niche craft that takes years to get good at it and there are fewer and fewer new glassblowers who make scientific glass each year. Home based self education is where I started and could only ask a glassblower a few pertinent questions when I got stuck. Perhaps this can inspire a new generation to keep the skill alive.

There are plenty of youtube videos out there and there are facebook communities dedicated to lampworking and scientific glass as well.

A good place to start is the many societies of scientific glassblowers, and their facebook pages are a good source of knowledge and resources.

Damn. I find glassblowing cool already but I saw a video of a 4 necked RBF being made and it was so cool. I always find it crazy how practically all of my glassware was made by hand. I think my 3 necked flask was made by a machine though. It seems a bit too perfect. My other RBF are definitely hand made but hold up really well.

I hope people keep up glassblowing. It's a really cool art form and a useful one as well. It's just pretty niche which has its issues sometimes.

Glassblowing is on my todo list, it's so incredibly useful to be able to make your own custom glassware. So far I've been using a small propane/oxygen torch with disposable oxygen cylinders. Each oxygen cylinder is 100 liters at STP, so it gets expensive fast. I've mostly been playing around, I made a custom thermometer adapter for my still head and a gas discharge tube with a couple glass-to-metal seals from my deceased addition funnel. Fun stuff!

If anyone is interested, there is a guy in NC selling a glassblowing setup, including 2 oxygen generators, on Craigslist. The 2 oxygen generators are like the things they sell to old people for medical oxygen, but much larger and must generate a huge amount with 2 of them, and they represent much of the cost. But cheaper than buying cylenders of oxygen. I'd buy it if I had somewhere to put it, and more time to learn how. I was thrilled that I was able to unstick some stuck joints at work recently using a Meeker burner and a lot of force.

@chemetix. watched you videos. The craft reminds me of auto body work---a skill,art, love and aptitude rolled up. I quite enjoyed them.

the tools for glassblowing are very expensive... you need a lot of space too...

In Catalonia, Ireland... you can find some co. making repairs... in scientific glass.
Now I asked for a repair, a flat flange dn 100. to cut and paste a male joint cost me 202€ with taxes.

Amazing ! This guy is very talented, but at the end of the video I see that he wears only goggles and no face shield. I think the radiant heat of the 1700 C glass would burn his face ?
