It’s odd. There are several good reference books on Fostoria Glass, books on candle holders, books on depression glass, Viking Glass and more. But the books about Cambridge Glass that are readily available are different and harder to use. Instead of the gorgeous illustrated pattern guides we like – because they are so easy to use – we have several books that are essentially catalog reprints.
The Cambridge Glass Co., Cambridge, Ohio 1930-1934 shows glass from the early 1930s. It’s a useful reference to find pieces and shapes, and to get an overview of many etching and decorated lines.
What it is not good for is to tell exactly what you have nor its value and it’s hit or miss on listing all the pieces made in a given line. The Cambridge Collectors of America club published this and has also published books on colors and etchings. They are useful as study guides and I have identified many pieces with this one, but I usually find I need to do a little more research to determine exactly what my piece is. That’s OK; there are excellent reference sites like the one for Miami Valley Study Group linked here or the Chatabout site here.
Cambridge had several lines and used them all with multiple etches and put etches on multiple lines. That means that once you recognize a Cambridge line or an etch, you are at least half way to knowing your pattern.
Overall I recommend this book; just recognize that it is not a pattern guide with each pattern listed alphabetically and rich pictures of each one.
