Kiln-forming as a technique to shape glass was in use for centuries before the Romans developed glass blowing and yet it became greatly overshadowed by glass blowing. Today, however, modern glass artists have rediscovered the versatility of kiln-forming and are using its techniques to produce works of great beauty and strength. In this reprint of his classic book on the subject, Keith Cummings reviews the history of kiln forming and discusses the materials and methods that are involved. The text is illustrated with the work of an international group of artists.
