- Good start! Thank you. #chemsky #photochem
- Alright since a critical mass of photochemists officially joined it was about time to try and make a photochemistry/spectroscopy starter pack; hopefully this is a good start, feel free to reach out to be added! #chemsky go.bsky.app/Cyibs8fat://did:plc:vpuvcmtwpxlfyq6635y4gyei/app.bsky.graph.starterpack/3lauxe3la4w2j
- Very cool, that you found this gem. Did you also see the windows in St. Stephan created by Marc Chagall? The Gutenberg Museum and St. Stephan are the must-see locations in Mainz (apart from @unimainz.bsky.social if you love #chemistry and #science).
- Happy to see #Chemsky is off to a strong start! Some of the original mineral-based pigments used for printing are shown in this photo from a recent trip to Mainz, Germany taken at the Gutenberg Museum.
- Also in Mainz, the church of St. Stephan has windows created by Marc Chagall. It's probably the most amazing effect I have ever seen in a church. And I have been to Rome and Aachen, among others.
