The special qualities of glass--neither solid, nor liquid--have required glassmakers to develop special skills for transforming raw materials into finished objects. In A History of Glassforming, Keith Cummings approaches the history of glass through the practices and techniques of those who make it. This is a fascinating study of the nature of glass and the skills, techniques, and machines that have been developed to exploit its remarkable and mutable properties. As Cummings demonstrates, glass has evolved from a rare and precious commodity, to a familiar tool of everyday use, to an art form prized once again.
