Crystal flask



The crystal flask is a special type of Herblore equipment, made from crystal glass, which is in turn made from crystal-flecked sandstone. It will be used to make combination potions. Its some way similar to the normal Flask

Crystal flasks can only be created after completing the quest Plague's End since the crystal-flecked sandstone mine, the place to mine the crystal sandstone which is used to make the flasks, only becomes accessible after completion of the quest. The mine can be found in the Ithell part of Prifddinas.

Crystals flasks are made by using a glassblowing pipe with "crystal-robust glass", yielding 150 Crafting experience, which requires 89 Crafting; players may boost their level if below 89 but can not be assisted. After a sip of potion has been taken from the flask, it cannot be sold over the Grand Exchange; however, they can still be traded with other players. Assuming a player does their daily mining of crystal-flecked sandstone, they will gain a minimum of 7,500 crafting experience each day making flasks.
