I'm so glad you enjoyed the article. According to Andrew it took him many many hours of research and performing his own experiments. Some reproduced from ancient texts. A lot had to be left out due to lack of space. It should have been a book to be honest! In PART 2 you'll find more sulphur chemistr...

Hi Joel, Welcome and like you I started my university education much later in life (I was 27 when I started my Chemistry degree) and over the last few years been drifting more towards a more physics environment. I find all SCIENCE fascinating so I hope you learn a lot and know that everything is pos...

Hi everyone, I know this post should be under the Publications portal but for some reason I'm unable to do so. Sorry. In any case hope you all enjoy Andrew Szydlo's latest article publication PART 1 (open access): https://sciendo.com/article/10.2478/cdem-2023-0002 There are so many things to say &am...

Making lead glass pebbles doped with different metals, transition metal salts and metal oxides: Thanks @lemmi for your interest. I'll try and write a quick summary on how to make these simple and fast lead glass pebbles. The procedure is based on this but I have tweaked the recipe and added of cours...

Magnificent article! Thank you for sharing. :thumbsup: I've done some of these beads before but using chalk sticks instead of magnesia because I did not have any. I further went on into making coloured lead glasses after that. By doping mixtures of orange lead oxide, boric acid and zinc oxide with m...

So, nun es ist es so weit :wink: : https://www.youtube.com/watch?v=3cwcekm6wDQ Yes, another delightful Szydlo demo lecture about sulphur is finally available on the Ri YouTube channel. Hope you all enjoy watching it :lol: Many thanks again to @MarBs_Lab for his incredible electrostatic machine. Wis...

Bei etwa 1:05:00 geht's mit der Maschine los. Leider war die Luftfeuchtigkeit im Hörsaal wohl doch ein bisschen zu hoch für überzeugende Ergebnisse. Yes, unfortunately it was & we were running out of time as well. So could not continue playing with it. On the plus side, lots of children stayed ...

Absolutely! Lets hope there will be more opportunities to collaborate in the future!

Cheers

Thank you Markus for posting the photos and of course for constructing and sending the device to us. As you said the lecture was jammed-packed and it went on for almost 2 hours! The demo lecture was filmed and I will post the link when it is uploaded on the Ri YouTube Channel. Hopefully soon! szydlo...

Superb job Markus!
Once again you have made a thing of beauty.

Yes, please do and let me know how it goes. Easy to prepare and very impressive in person.
Thank you Markus.

Very impressive pictures! Perfect for halloween - congratulations! We have this experiment already documented here . But it seems that your version of burning alcohol with sodium chloride gives more impressive results. Thank you! Yes, the flames look almost like a CGI effect. Difficult to believe u...

Be afraid be very afraid of black flames! This is a great demo for Halloween. All about atomic emission and absorption spectroscopy as well as quantum theory.

Just marvellous

We made a very crude version with mercury a few years ago. Not nearly as good or beautiful as this one.

Cheers,
