I know it's not that relevant, but isn't hydrofluoric acid a different and much more reactive acid than hydrochloric acid?

Now imagine being the teacher, trying to proceed with the class when they first open it at this page.

Totally agreed, that's the p(l)an.

A very slight clarification here:

cheap to make alumin

Scientists are your best bet, I guess. I wish I could cite you studies, but I would have to search, as well. I might soon.

UPDATE: This far all I got was 'best to be careful' or 'staying away never hurts':

These findings challenge the assumption that PTFE particles are biologically inert, highlighting hazards arising from their physical interactions, especially at the nanoscale. Given the relevance of the co-culture in vitro model of intestinal barrier to human intestinal physiology, the results underscore potential intestinal health risks from PTFE-MNPL exposure. Future studies should focus on chronic, low-dose exposures to elucidate the specific cellular pathways activated by PTFE-MNPL exposure.

Due to toxicity concerns, PFOA has been replaced with other chemicals such as GenX, but these new alternatives are also suspected to have similar toxicity. Therefore, more extensive and systematic research efforts are required to respond the prevailing dogma about human exposure and toxic effects to PTFE, PFOA, and GenX and other alternatives.

I have a non-stick, and I use it rather infrequently. I have read about the effects of damaged coating, and GOD I would throw it away immediately as soon as I see ONE flake in it. Maybe I'm just overreacting it, but I treat it like it was a delicately covered layer of asbestos.

It's great and smooth NOW, but I'm only using it until I see a noticeably hard scratch. Until then, I get rid of the oil and juices with a paper towel immediately after cooking (and I'm already slightly worried that the dry paper could be too abrasive on the dry bits of the pan), and I leave it to cool down before I wash it to prevent it from heat stress.

I might be overthinking it. But I'm playing with the thought of getting a cast iron or carbon steel already.

I had to read the title 3 times, because even for the second read through I read 'NATO is preparing to comfort Russia'.
