For more than 1,800 years, glass was hand-blown into molds or shaped freeform, a labor-intensive process. It wasn’t until the 19th century that glassmakers developed a technique for machine-pressing molten glass into molds, enabling them to create elaborate designs quickly. Production of such pressed or pattern glass skyrocketed, prices fell, and, suddenly, customers of all income levels could assemble matching glassware sets to pair with their china services.
Pressed glass manufacturers popped up in nearly every region of the United States. Here in Maine, we had the Portland Glass Company, established in 1863 in a four-story brick building on Commercial Street. Within two months of opening, the firm was manufacturing 5,000 pieces of glassware a day, and by 1865 it employed 100 workers. When it closed in 1873 — a victim of high materials costs and a national economic downturn — it had produced more than 60 glass patterns.
Some pieces resemble traditional hand-cut vessels; others took on shapes and patterns, such as dots, rosettes, garlands, and leaves, that could only be created with the new technology. Rare colored and limited-production examples, like the pear punch bowl pictured below, may fetch well over $1,000. But common clear items can be found for $10 to $100, making it possible for just about anyone to own a piece of Portland’s glass-producing history.
