Hi everyone,
I thought this was interesting because of how it ties in with my years of learning how to do fresco.
The first link is an article about how scientists may have cracked the secret of why Roman concrete has lasted for thousands of years. The second is a video of when I made a batch of quicklime back in 2011, for the purpose of painting frescoes.
I hope you enjoy them, and if you have any questions or comments feel free to send them to me.
Best regards,
James
