*A lamp for producing Is used as a personal lightsource. * Fill it with 0.13kg 13 kg of [[olive oil]] or [[tar]], then light it with a [[steel and flint]].* Oil is rumored to produce light for longer than tar.* When full it will burn for almost 24 hours depending on [[quality]] (further studies are needed to determine more precise burn times).* The lanp quality determines how far it can illuminate.* If the lanp is [[dye|painted]], the light from it will be that color. Black dye has no effect on the light of the lanp though.
*Brass oil lamps have been shown to be marginally more fuel efficient compared to iron lanterns, and also decay through general use much, much slower. The only drawback is that they require [[brass lump|brass]] to improve instead of [[iron lump|iron]].
