Pressed glass in imitation of cut glass was made in nearly all the American glassworks in the late 1820s. Pressed glass with delicate sparkling patterns is called lacy glass. Characteristic motifs of design include scrolls, hearts, acanthus leaf, sunbursts, peacock, feather, fleur-de-lis, roses, and other leaves and flowers. Historical patterns, including the American eagle, were also popular. Many articles of tableware were made in lacy glass, but the cup plates and salts are the most interesting for the collector because of the diversity of patterns. Historical cup plates include such subjects as George Washington, Henry Clay, and Major Ringold as well as center motifs of ships, log cabins, steam coaches, plows, and the Bunker Hill Monument. The greatest number of cup plates are made in clear glass, but some were also made in amber, blue, green, amethyst, yellow, and opaque colors, including opal. Designs on salts also vary from lacy designs, and those imitating cut glass to historical motifs. Early lacy-glass salts were rectangular with feet and pilasters at the corners and a single motif, such as a rose or basket of flowers, on the ends and sides. Other salts were round or oval and had lacy patterns such as scrolls, rosettes, shells, and leaves. Historical salts include the Washington-Lafayette; the "Lafayet" boat-shaped salt; eagle salts; "Providence"; and "H. Clay" salt with an engine and car.
