The arms are the part of a chandelier that stretches the widest from the central support and are the main light-bearing part of the chandelier since candles or bulbs are located at their extremity. They can be composed by multiple shapes of glass held together or by a single simpler piece of glass.
The plates are the metal or wooden blocks located on the central support, into which the arms slot.
it's a glass dish positioned just below the candles at the end of the arms, originally designed to prevent drips of wax to fall from the chandelier.
finials are decorated shapes of glass hung at the very bottom of the central support. Many chandeliers also have finials hanging from glass rings on the arms.
Typical type of glass used in the venetian chandeliers. It was renowed because of its ability to be worked longer when heated and be therefore shaped into curving leaves and flowers. Soda glass, also famed for its lightness, contained a small quality of lime, giving it clarity and making it completely different from all other types of glass produced at the time.
