A paperweight is a small solid object heavy enough, when placed on top of papers, to keep them from blowing away in a breeze or from moving under the strokes of a painting brush (as with Chinese calligraphy). The decorative paperweights are usually in limited editions, and are collected as works of fine glass art, some of which are exhibited in museums. First produced in about 1845, particularly in France, such decorative paperweights declined in popularity before undergoing a revival in the mid-twentieth century.
Most paperweights, which are considered works of art, use one of the following techniques; millefiori, lampwork or sulphide — all techniques that had been around long before the advent of paperweights. A fourth technique, a crimp flower, usually a rose, originated in the Millville, New Jersey area in the first decade of the twentieth century. Often called a Millville rose, these weights range from simple folk art to fine works of art, depending on the maker.
