Pressed glass (or pattern glass) [1] is a form of glass made by pressing molten glass into a mold using a plunger. [2] Although hand pressed glass has existed for over 1,000 years, the use of a machine for pressing was first patented by Pittsburgh glass man John P. Bakewell in 1825 to make knobs for furniture.
Historically, cut glass was shaped using "coldwork" techniques of grinding or drilling, applied as a secondary stage to a piece of glass made by conventional processes such as glassblowing. [1] Today, the glass is often mostly or entirely shaped in the initial process by using a mould (pressed glass), or imitated in clear plastic. Traditional ...
Pressed glass is patterned only on the exterior and smooth inside. [26] Pressed glass, termed “mold-pressed,” has an interior form independent of the exterior, in contrast to mold-blown glass, whose interior corresponds to the outer form. [27] Plates, lamp bases and door knobs were usually made of pressed glass. [28]

[1] Machine-made, molded glass products are ...
Mechanical pressing of glass reduced the time and labor necessary to make glass products, which lowered costs and made glass products available to more of the public. [32] An 1884 U.S. government report considered mechanical pressing and a new formula for glass to be the two great advances in American glassmaking during the 19th century. [ 25 ]

The bases of bowls, platters, etc. were ground so they would sit evenly on a table. Many patterns of Elegant glass were embellished with acid etching, cutting, enamel decoration ...
Although glass was made at Jamestown, production was soon suspended because of strife in the colony. A second attempt at Jamestown also failed. Later attempts to produce glass were made during the 1600s; glass works in New Amsterdam and the Colony of Massachusetts Bay had some success. In the 17th century, at least two New Amsterdam glass ...
