|A barrel full of toxic naphtha.|
Toxic naphtha is a quest item used in the Mourning's Ends Part I quest. It is made by using a sieve on a barrel of naphtha apple mix. The player must use it on a range to turn it into some toxic powder which must then be used as a non-lethal poison to make the residents of West Ardougne ill.
When used on a fire, it will cause a big explosion similar to Nitroglycerin, and will deal a lot of damage.
