Thought the hazard ID and management was well done.

2024-04-01 13:32:44 +0000 UTCits not a bad idea. but what makes me hesitate is that glassware under vacuum has a chance of imploding. It's rare, but it can happen. And heating glassware under vacuum increases that chance too. I don't have a vacuum good enough to bring the boiling temperature below 60 celsius where sulfuric acid becomes considerably safer. So if the boiling temperature just goes to say, 200 celsius, and now we have an implosion danger, then not only will i have not really solved the heating problem, but now i've added the danger of acid being outright thrown at me if something should implode. But i think i still might try it someday, i do trust my glassware and safety procedures to handle it even if i can only bring down the boiling to 200 celsius.

2024-04-01 13:09:47 +0000 UTCWould you ever consider adding a glass aspirator vacuum pump? It could help drive down the hot temperature requirements as well as help contain some of the toxic fumes. The additional challenge here would be to ensure that you don't suddenly increase the applied vacuum... not sure if there are other dangers. For me, the timing of this video couldn't be better. I was planning to do this exact experiment this summer, and I was quite concerned with the dangers involved. I had planned for everything mentioned in this video, so I guess I'm not far off from a reasonably safe experiment. As always, thanks for the content!!
