Florences' Glassware Pattern Identification Guides are great companions for the Florences' other glassware books. This fourth volume in the set includes more than 400 patterns, with no repeats from any of the other books. Carefully planned close-up photographs of representative pieces for every pattern show great detail to make identification easy. With every pattern, the Florences provide the names, the companies that made the glass, the dates of production, and even the colors available. These guides are ideal references for novice and seasoned glass collectors and dealers, and will be great resources for years to come. 2005 values. Almost all of the pieces in this book do not appear in the three earlier volumes. Their maker and date of manufacture is listed as accurately as possible - but, as the authors state, nothing is written in stone. Some pieces were made for many decades, and sometimes in different colors at different times. Sometimes molds were traded between companies. Some companies had molds made that imitated earlier pieces. There is much that is not clear cut about glass identification.
