Soaper
A soaper is a person who practices soap making. It is the origin of the surnames "Soper", "Soaper", and "Saboni". Roads named "Sopers Lane," "Soper Street," and so forth often were centres for soap making.
Historically in England and in the United States a chandler is a person in the soap and/or candle trade.
Craft-scale soap making has a variety of adherents, both those who practice it as a hobby and to keep traditional soap making methods alive, and consumers who prefer traditional handmade products as alternatives to mass-produced industrial offerings and as a contribution to a more sustainable means of living.
A "soaper" is also slang for Quaaludes.
