This mod is named real_torch, changes torches so that they have a life of 20-30 minutes which is configurable using the torch_min_duration and torch_max_duration settings. It also can be relight using coals, flint or steel, and can be affected by water.

2x coal lumps can be crafted into 12x coal powder
coal powder and an unlit torch can be crafted into a lit torch again
punching an unlit torch with coal powder relights it
punching an unlit torch with flint & steel relights it
punching an unlit torch with gunpowder explodes and relights it
never punch a lit torch with gunpowder, ow!
water near torches make them drop as unlit torches
coal powder can also be used for fuel or crafted into black dye
