The Art of All Colours, Mediaeval Recipe Books for Painters and Illuminators by Mark Clarke
The Archaeology of Medieval Bookbinding by J.A. Szirmai
Mediaeval Painters' Materials and Techniques, The Montpellier Liber diversarum arcium by Mark Clarke
I've finished reading the Art of All Colours and while most of the book is filled with information on where to find or what books contain information about medieval painting it does have a very informational introduction. Not a book for everyone, but with it's lists of manuscripts it will open new areas to research into for more information.
I've also started reading the other two. So far the Bookbinding book, is very interesting and I love all the images. It makes me want to hurry up and try to do some binding.
Painters' Materials and Techniques so far has been a fascinating look at how the information was transported and adapted into the LDA (Liber diversarum arcium). The rest of the book looks just as good as the start. After the Formation of the LDA, comes an overview of painting, then the translation, a section on commentary and discussion, glossary, the latin text, and finally the appendixes.
