Potion flask

The Potion flask was announced in the 2012 February Behind the scenes. It is a player-made item, requiring 89 Crafting, which is crafted from Robust glass by using the Robust glassmaking machine in Oo’glog after completion of the quest As a First Resort. The flask holds up to 6 decanted doses of a potion and will shatter upon being emptied of its contents, and despite being created entirely of non-tradeable materials, the flask is able to be traded. Because the resources required to craft Robust glass are non-tradeable and have a maximum of 50 available to players daily, Potion flasks will be in short supply as well as high in demand, and it is Jagex's hope that players will find making them profitable.
