Really interesting--would love to know more like what they used with these materials/ingredients to get different colours. I have taken a few art history courses, but I just realized I've never really thought about (or learned about) how the paint was made.
You may be interested in a book (somewhat related) that's written by an author in my city. It's called The History of Ink by Ted Bishop.
Will be making daily post as I educate myself of what I learn each day. Tomorrow might interest you as it will start hopefully be able to finish pigments. How and from what it was and is today made from.
