Betty lamp
The colonial iron lamp with lid and spout, burning tallow or fish oil.
The Betty lamp came to America with German and Scandinavian settlers and was common until kerosene arrived. The name probably comes from the German besser, better. Examples are in the Smithsonian and many local museums.
Materials: Wrought or cast iron, sometimes brass or copper
Manufacture: A shallow lidded bowl wrought or cast, with a spout for the wick and a hook to hang it by.
The covered bowl and short wick spout – not an open dish like older lamps.
The hook and chain that held the lamp at the hearth or table.
