Reply to comment by newsreadhjw in A study using eggs reveals why Italian Renaissance masters – artists such as Sandro Botticelli and Leonardo da Vinci – might have added protein to their oil paintings. by molrose96

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.
