I’m a little surprised the way this is written as if it’s some kind of discovery that egg protein was found in paint. Painters have been using egg tempera technique for a really long time. I’m no art expert but I did catch an Andrew Wyeth exhibit once and I remember they talked about this a lot. I thought it was well understood how this worked.

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.
