Soda ash

Soda ash is obtained from cooking seaweed on a range or fire. It is an ingredient for making glass in crafting, along with a bucket of sand. It must then be smelt in a furnace to make molten glass.

Soda ash is usually obtained by gathering seaweed or swamp weed in areas such as Dorgesh-Kaan, the beach near Rellekka and Keldagrim, Entrana, or Karamja.

It can also be puchased at any of the Charter Ships for approximately 5 coins.
