Query: Materials yes - Techniques not really

I wish I'd read the other reviews carefully before ordering this. I have The Practice of Tempera Painting by Thompson (which is very detailed on the technical aspects of tempera painting) and I was expecting something similar here. Unfortunately it is heavy on material info (mostly about the pigments used) but almost nothing usable about medieval painting techniques or methods.Since most of the pigments mentioned are extremely toxic it's doubtful the book would be of much use except as a source of historical information. I, for one, would never have these pigments (lead, arsenic, mercury, etc) in my studio in powdered form. Very dangerous stuff!
