For connoisseurs and glass collectors, this is one of the most important publications in its field. Where the McKearin's earlier book, American Glass (Crown) covered the broad field, this specifically explores not only facts long known, but much recently uncovered material concerning that choicest of glass collectors' items, blown glass. Many hitherto accepted claims are exploded; even new claims are qualified by ""One generation's truth frequently becomes the next one's myth."" To many collectors, their contention that identification of Wistar glass is virtually impossible and usually wrong (they place most of it as coming from some of the many smaller glasshouses of South Jersey, outgrowths of Wistar employees) -- will be unwelcome news. To a lesser extent they make the same strictures in regard to Stiegel glass. They examine with care the records, the advertising, of post-war glasshouses; they trace the developments, the characteristics, the continental influences, the difficulties encountered as new houses opened, through the critical period 1800-1830. To Bakewell they attribute the impetus for tableware, soon cheapened as pattern glass, as mass production developed. But even throughout the subsequent years, some individual blown glass was produced here and there, a sort of surviving American folk art in glass, difficult to identify, but with recognizable characteristics. A final chapter deals with the modern renaissance of glass. Important for advanced collectors -- museums, etc. More than 400 illustrations, including 115 photographic plates and ten pages in full color, make the book fascinating for anyone interested in glass. The accompanying captions are in themselves a concentrated study in the field. Among special points to note, in selling this book, is the assemblage of identified pieces from the 18th century factory of Amelung. Oversize format, slipcased.
