An oil lantern frame can be made by members with level 26 Smithing from an iron bar, giving 25 Smithing experience. It is used with an oil lamp (empty) to make an oil lantern (empty) which can be made with level 26 Crafting. The empty lantern can then be used with lamp oil at the Chemist's west of Rimmington to make oil lantern (oil). The oil lantern frame can be used directly with an oil lamp (oil) to create an oil lantern (oil). Oil lanterns can be lit with a Tinderbox at level 26 Firemaking to make a lit oil lantern. They will eventually go out and require more lamp oil.
