In medieval Britain, a chandler was a person who made what items?

A chandlery was originally the office in a medieval household responsible for wax and candles, as well as the room in which the candles were kept. It could be headed by a chandler. The office was subordinated to the kitchen, and only existed as a separate office in larger households. Whether a separate office or not, the function was naturally an important one, in a time before electric light, and when production of candles was often done privately. It was closely connected with other offices of the household, such as the ewery and the scullery. With this use, the term is largely obsolete today but can refer to a candle business. As such, a "chandler" is a person who sells candles.
