Minding my own bismuth
Jan. 17th, 2026 08:38 amA-level chemistry was a ton of fun in a bun. I didn't plan to take it any further; what I would really have liked to have got into was particle physics, but I genuinely couldn't see that anyone would ever let me use the extremely expensive equipment that was required for that (expensive stuff was for other people), and so I chose to do a maths degree simply and solely because it didn't need any special equipment. Yes, I had an incredibly low opinion of myself at the time, but don't blame me for that. I'd been taught to have it for my entire childhood.
But the chemistry was interesting and a good diversion, especially since it was regularly enlivened by the misadventures of one of my classmates. His surname was Pringle, and his father apparently wrote occasionally for a well-known BBC TV series; be that as it may, he was ridiculously accident-prone, especially during chemistry lessons. It wasn't that he was stupid. He was just so ham-handed that, in any chemistry lesson, you could pretty much guarantee he'd manage to melt the end off a test tube, explode something, or at the very least get a completely unexpected result from his experiment. To be fair, he actually wasn't the one who managed to spill a beaker of pentane over the lab bench and then accidentally set fire to it, almost taking his eyebrows off in the process; that was another bloke, and it almost certainly was the deciding factor regarding why he got the sixth form prize for maths and I got the corresponding prize for physics and chemistry, when we were both neck and neck in both subject areas right through the sixth form. I'd rather have won the maths prize, since that was what I was going to do the degree in. But hey. Pringle, incidentally, grew so notorious that his name became a verb (as in "oh dear, I'm afraid I rather pringled that one up"). I occasionally wonder idly what happened to him.
Most of our public exams were run by the rather alarmingly named Joint Matriculation Board, which sounded like a piece of equipment used by a particularly over-enthusiastic physio; however, A-level chemistry, for some reason, was Nuffield. And the Nuffield syllabus required that you did a project, which you could choose from a set list (I think there were about half a dozen options). Almost the entire year did food science, because it was, basically, noddy; we'd already covered most of the work in O-level biology lessons (there weren't very many of us in the chemistry group who hadn't got a biology O-level). And I looked at the list and thought "I am not doing food science, because it is, basically, noddy. I should like to do metallurgy, because I have never done any of that and it sounds a whole lot more fun."
I was the one person in the entire year who did metallurgy (or, indeed, anything at all that wasn't Easy Food Science Option). Fortunately, I already had a reputation as an anti-Pringle. I'd never broken or damaged a single piece of lab equipment, I was known to be dexterous and careful, and my experiments worked the vast majority of the time. So they just let me do it unsupervised. I'd arrange to come into the lab during the lunch hour, they'd leave the stuff I needed out for me, and I'd get on with it.
Nobody would ever let sixth-formers do that these days. I doubt they'd even let undergraduates do it. I was making alloys from cadmium and bismuth, polishing the samples down, and studying their crystalline structure under a microscope. Of course, they did have at least some basic regard for safety; the book told you to do your melting in a fume cupboard, which, naturally, I did. And I, being a cautious type, had read up on the metals I was going to be using and discovered that cadmium is bloomin' toxic and you do not want any contact with it at all, so as well as my regular lab coat I also provided myself with a pair of elbow-length industrial-spec rubber gloves, which I wore all the time I was in the lab. I was also extremely careful about how I cleaned up. I wasn't going to expose anyone else to metal dust containing cadmium.
On the whole, I have to say I'm glad that safety measures are a great deal stricter now. Most sixth-formers fall somewhere on a scale between me (ultra-cautious, to the extent of doing my background reading before handling unknown substances) and Pringle (enough said), and I wouldn't want to see most of them handling cadmium.
Nonetheless... I'm still really grateful they let me do it.
