I found a new low cost purchasable source of low cost potassium alum in Canada.
The dollarama has just received these crystal deodorant sticks which are pure potassium alum called Cuticura (120G) in a stick format. It's 3 dollars. It's imported by a company in Montreal and states that it is pure 100% potassium alum.
