Juju mining flask

A Juju mining flask is a potion flask originally containing six doses of Juju mining potion. It is created by using a juju mining potion on a potion flask.

When a dose is consumed, each ore mined has a 10% chance of finding a stone spirit, which will automatically smelts some of the ores you mine, leaving the bar of metal in your inventory and giving you the smithing experience you would have gained from smelting it.

The flask is made by blowing robust glass, requiring 89 Crafting and giving 100 experience. Red sandstone can be mined at Oo'glog and smelted using the Robust glass machine also located at Oo'glog.

To decant the potion into the flask, one must have at least 6 doses of juju mining potion in their inventory, as well as one or more potion flasks. Using the flask on the potion will open a menu to decant them. The optimal inventory setup for decanting potions is 17 4-dose potions and 11 flasks.

Once the potion has been partially drunk, no more doses can be added to it. After all six doses have been consumed, the flask will shatter and disappear.
