the world is running out of glassblowers and yet you want to become a fucking doctor
One of the most jarring moments of my university education was in a physics class when I was given a device that measures gravity and was told “this cost the university sixteen thousand dollars, but the only glass blower in the world who could make the glass springs inside it died so it’s literally irreplaceable. If you drop it those springs will shatter. Go fuck around with it for a day and take some measurements”
In the UK there's a thing called the endangered crafts list which I highly recommend if you fancy discovering some crafts you never even knew existed. Scientific and optical instrument making is considered 'critically endangered' and glassworking (scientific glassware) is just considered endangered, which is for 'crafts with a shrinking market share, an ageing demographic or crafts with a declining number of practitioners.' There's some other crafts in that category which are easier to teach yourself or go to classes on that list, like lithography, marbling or block printing on fabric, so it might be worth considering those if you're looking for something to try.
