Producers of early American pattern glass (EAPG), also known as pressed glass, designed many different patterns for this economical and popular glassware, which was made in cast-iron molds. Manufacturers obtained a patent on each pattern and its name to avoid having it duplicated by other companies.
Competing glass producers would often turn out very similar patterns or similar names, altering the finished product to avoid exact duplication. In addition to the most-popular geometric designs, some patterns featured animals, fruits and flowers in fine detail. Some of the patterns were produced as full table settings, while others were produced only in goblets or single pieces. Collectors today can choose from more than 3,000 patterns produced in early pressed glass. One of the most enduringly popular pressed glass patterns was the Fostoria Glass Company’s American pattern.
