The Glass Industry in Sandwich is a five volume series of books presenting a factual account of glass produced by the glass companies that were located in Sandwich, Massachusetts, between 1825 and 1922. Included are color photos of over 2300 Sandwich glass objects that have been thoroughly researched and authenticated by Sandwich glass experts Raymond E. Barlow and Joan E. Kaiser, who have worked together for twenty-two years. Recognized by the antiques industry as the "Bible" in its field, this magnificent set of books has become a trusted reference used by glass curators of major museums as well as by early American glass collectors, antiques dealers and auctioneers. Each photo is accompanied by dimensions, approximate time of production, and captions that detail methods of manufacture and sources of documentation. Comparisons are made between objects manufactured in Sandwich glass houses and objects produced in foreign and other American factories. This final volume contains 283 color photos of a variety of objects, from very fine cut and engraved ware to household, commercial, and scientific necessities that came under the heading of "general assortment" when they were marketed in the 1800's. A supplement to Volumes One, Two, Three and Four features objects that were not available for study at the time the books were written. A roster of 1500 employees and their occupations is included as an aid to documentation. There are still bargains to be had for as little as $10 as illustrated by the little-known or previously undocumented pieces pictured in this volume. Extremely rare articles have increased in value to as much as $35,000. Authorities Raymond E. Barlow and Joan E. Kaiser present to you a compendium of glass identifiable and collectable as Sandwich glass. A price guide is available that lists prices for each piece in clear and assorted colors, and updates the prices listed in previously published Barlow-Kaiser price guides.
