Glassmakers enrich pressed Vaseline glass with uranium oxide, which imparts a yellow-green luminescence under UV light. Collectors in the late 19th and early 20th centuries favored it for creating decorative pieces like vases, bowls, and plates. Among the many types, Vaseline glass ranks among the most valuable pressed glass.
Glassmakers produced opaline glass—a type of decorative opaque glassware—in great numbers during the 1800s. They frequently used it for decorative items like vases, lamps, and goblets. Some of the most sought after opaline glass patterns include the “Bristol” pattern, as well as “Satin” pattern. Collectors often consider opaline glass to be valuable pressed glass.
The Akro Agate Company was a glass manufacturer that produced pressed glass & a particular type of glass known as Akro glass in the early 1900s. Manufacturers frequently employed it for marbles and children’s toys, as well as kitchenware like measuring cups and mixing bowls. The “Popeye” pattern and the “Corkscrew” pattern are two of the most valuable Akro Glass patterns. Many collectors regard Akro Glass patterns as some of the most valuable pressed glass available.
