The Hallmarks of an Adam Chandelier
Adam style chandeliers are similar to the Georgian style but will include the Greek urn shape in the middle of the shaft. Most Adam style chandeliers have two tiers of arms with the upper tier supporting triangular spikes or spires. The solid arms are usually ground with six flat sides (hexagonal in section) and four rows of thumb cuts. The "Van Dyke" style drip pans and candle nozzles are removable and are attached to the arms with metal ferrules. Adam chandeliers have both top and bottom canopies. Dressings are usually pear shaped buttons with larger pear shaped pendant drops.
Towards the end of the 18th century, crystal wall sconces began to appear. Their design closely followed the style of the table candelabra of the same period and offered a practical solution to lighting larger rooms.
