Robust glass detail.png

Robust glass is a thick type of glass used for creating potion flasks or 10 of them is used to create an ogre flask. It is created by melting red sandstone in a robust glass machine, which can be found southwest of the mud bath in Oo'glog or by the pottery oven in the Ithell district of Prifddinas. The machine requires completion of As a First Resort to use.

It is also given in varying amounts by Chief Tess as the recurring reward for completing each of her Archaeology Collections. The first of which - Blingy Fings - requiring 69 Archaeology to complete.

Melting red sandstone has no skill requirements, but creating potion flasks from robust glass requires level 89 Crafting and gives 100 Crafting experience. This requirement can be boosted, but it cannot be assisted. Strange and golden crafting rocks can be obtained from creating potion flasks.
