The Painters Handbook by Mark Gottsegen
If you're teaching yourself to paint, reading through The Painter's Handbook will be like attending several semesters of Art Materials 101. If you're at art college and frustrated by the lack of practical information about the materials you're working with, it will fill the gaps. If you're an experienced artist looking for specific information, such as the properties of a particular solvent, you're likely to find it all in here.
