I don’t know. I’ve never been able to get them to work properly. I’ve been told if you let them sit too long with old oil in them, something happens to the wicks and makes them unusable. I would have to clean out the oil residue and put new wicks in them.
I’ve also got a nice cut glass glass living room lamp and lampshade that uses a globe and mantles. It’s meant to burn gasoline I believe, or maybe coleman lantern fuel. I’ve never tried to use it.
The oil becomes waxy by evaporation and the wicks become saturated with the residue. Then when you try to light it, it smokes terribly and stinks......
