Quick Summary

Blown three-mold refers to a glassmaking technique where molten glass is blown into a mold made of two or more pieces. This method is used to create glassware that imitates the appearance of hand-cut glass.1

This technique was particularly employed by the New England Glass Company in the 19th century. Vessels were formed by blowing glass into molds that featured decorative designs, often adapted from cut-glass patterns. These molds were hinged in two, three, or more sections, allowing for the impression of geometric, arch, or Baroque patterns onto the glass. By 1830, this method began to be superseded by the more efficient pressing machine.2
