American Glass Research has published a book entitled Color Atlas of Stones In Glass. This hardbound book describes 39 stones, accompanied by more than 300 original color photographs, images and spectra. The Color Atlas is printed on high quality photo paper and is over 120 pages. Detailed identification tips, compositions, causes and sources are given for each stone, as well as its physical and crystalline characteristics. This Atlas is intended to facilitate identification of the most common glass stones across the four major glass industries: container, tableware, flat glass and fiberglass. This volume focuses on practical assistance with the identification of stones through color photographs. Furnace operators, quality control engineers or filling line incoming inspectors will obtain the most use from this guide, as they are responsible for the day to day monitoring of glass quality. The Color Atlas cost is $150 and is available on Amazon or directly from AGR.
