Features
The Tudor period used oak woods, had intricate carving and inlays of expensive wood. The Jacobean period used oak and walnut, Cromwell style used oak and walnut accented with inlays of mother-of-pearl, bone or ivory. The Carolean period used mostly walnut. Veneers came into prominence as did marquetry (small pieces of colored wood) inlays, lacquer and silver. The William and Mary period had a Dutch influence. The Queen Anne style featured walnut and walnut veneers as well as lacquer and silk and needlework upholstery.
Early Georgian featured gilded pieces and marble table tops. Mid Georgian was the time of Thomas Chippendale, who used imported woods such as mahogany and Virginia red walnut. The Later Georgian period included three major designers: the Adam brothers, Hepplewhite and Sheraton. The Adam brothers were influenced by Greek and Roman works of art. Their carvings featured honeysuckle, ram's heads and feet and husks. George Hepplewhite's chair backs featured heart or shield shapes. Thomas Sheraton had inlays of an oval shell made of satinwood and had intricate shading.
The Regency Period pieces could have the Greek and Roman gods, lyres and lion's paw foot, Egyptian features like sphinxes, columns and crocodiles, or Chinese patterns and colors with brass inlays and gild bronze. William IV style is very similar to the Regency, but it's much heavier and can actually look clumsy.
Identification
Tudor furniture can be identified by legs that have knobs on the top, middle and bottom. Jacobean had very simple, straight legs. The Cromwell period had decorative columns on the front. The Carolean period had tall chairs decorated with cherubs and the seat and back were caned. During the William and Mary period, the legs had knees and were decorated with carvings of shells. Chippendale can be identified by the ball and claw foot. Hepplewhite's pieces were done on a small scale. Sheraton's furniture was slender and tall with turned legs. Regency legs started out being shaped like a saber, but in the late period, they were straight. William IV style had tapered and carved legs.
Considerations
Genuine antique furniture can be identified by the way it's put together. Joints in the drawers of the earlier periods did not have nails. They were notched and held in place by wooden dowels. The handmade nails of the later periods are obviously irregular in appearance.
Warning
Modern furniture polish can be harmful to old wood, which can reduce the value of an antique. Dust with a soft cloth and use paste wax to preserve the finish.
