Rare. An early discussion of the preparation and use of paint pigments. Such pigments are commonly made from animal, botanical and mineral products. However, pigments of blue color were the most difficult and expensive to make with the very best blue paint usually being made by pulverizing the precious stone lapis lazuli that was found in Afghanistan. This book discusses the color blue, its preparation and the best ingredients to create a pigment. The mineral olivine is also discussed for use in the preparations to present a greener hue to the paint.
