Being a hobby glassblower is a bit different from being capable of the specialized and delicate work it takes to make parts for scientific instruments.

You'd genuinely be surprised. I mean obviously you're not going to be making this stuff after like a week, but a lot of really impressive work is done by hobbyists.

Edit: But also im not saying that every hobbyist should be making scientific equipment, its just interesting that a traditional craft intersects with modern science, and that commodity fetishism means that a lot of us (Including myself) don't consider stuff like that

Also are people really keeping high temperature kilns in sheds?

Literally yes
