Recipes for 125 modeling materials are provided here with lists of ingredients, step-by-step instructions, hints for use, and variations. Each one-page recipe is accompanied by clear, helpful line drawings. Symbols indicate mixtures that require cooking; that can be baked for permanence; that will air dry; that are edible; or that require adult supervision, while giving appropriate user ages. Mixtures include variations on the familiar salt, starch, and bread-dough recipes plus those requiring a wide variety of other materials--including zonalite, dextrin, whiting, gesso, paraffin, putty, spackle and vermiculite. Here is everything from bones for the dog, sand sculpture, and silly putty to peanut-butter play dough--a useful guide for the experienced art, day-care, or early-childhood teacher. Novices would benefit from more information on the advantages of mixtures for specific purposes and from suggestions on how to clean utensils, work areas, and children. A resource guide lists commercially available modeling products. Brief ""Where to Find"" list; bibliography: indexes by project and material.
