Volcanic sulphur is a rock found in the Lovakengj sulphur mine on the northern side. Mining volcanic sulphur requires level 42 Mining to obtain and grants 25 Mining experience.
While mining in the sulphur mine, players should wear a form of face protection (face mask, gas mask or slayer helmet). Without protection, gas clouds within the mine will deal large amounts of damage to unprotected players. If the player wears any form of protection against them, the damage taken will be reduced by roughly 80% instead.
It is recommended to mine the volcanic sulphur deposits from the south or from the west to avoid taking excessive damage since the gas clouds cannot damage you when directly south or west of you.
Volcanic sulphur is used along with juniper charcoal, saltpetre, and a pot to create a dynamite pot, which is then added with a ball of wool to create dynamite, an item used to participate in the blast mine.
