Yeah, I read the original study which is about how they added egg to their oil paints. Egg tempera involves just egg or milk.
I’ve never heard of that, but the old masters shared their techniques with apprentices in their studios and not with historians.
Only in the last 30 years have we realized they were all using lenses. So, we’re still working out how they did what they did.

My first thought was that this could affect our estimate of mass in the universe, which would have bearing on questions of antimatter.
but it’s likely a tiny overall difference compared to the black holes at the center of galaxies?

watching the indigenous trees beginning to struggle here in the pacific NW of USA, I’ve been wondering what we should plant.

The chemistry is more complex. The protein creates microstructures in the paint allowing better impasto or thick, textured applications of paint, among other effects.
