This introduction to the most innovative period of glass making in the twentieth century is a beautifully illustrated reference guide to the work of the great designers and firms of the time. The historical background of each artist and company, the description of their styles and techniques, and the evaluation of their achievements make this an invaluable guide. Contemporary photographs of glass artists and glassworks, examples of signatures, a glossary, and a biographical list of artists help put the development of art glass in historical perspective.
