Grade 3-6–These books fill a niche in library collections for artists' works with the featured materials. Each one has a similar format with clear, large photographs and illustrations. Clear, easy-to-read texts fill about one half of each page. Chapters begin with what the material is (such as the charts of types of stone and characteristics of metal), examples of artwork made with the featured medium, history, treasures (usually of the past), and techniques used to produce a finished piece of art (e.g., cutting and polishing in Stone, hand building in Clay). Case studies feature an artist or an example of the art form, as well as a student project. There is information about contemporary techniques as well as those that are more traditional.
