There are lighters based on this, saw one on a ray mears show. The wick is soaked in saltpeter and placed in an open end tube, another tube with sparker wheel and flint is welded next to it and used to ignite the wick, which smolders and can light other stuff until it's snuffed with either your finger or a ball on chain.
