Here is a nice example of a 19th century whale oil lamp. It has 3 burners and shades that I guess would have glass or some kind of material on those shades. I have had it a while and of course it is very old. I had lit it when I first got it to see if it would still work and it did. But when I was forced into a near week of no electricity, lighting became an issue, it was pressed into service and was very useful in providing light, heat, and comfort during those very dark days in October.
Here is that lamp doing what is was designed to do all those years ago.
