Hello, I was wondering if someone could enlighten me as to the
actual chemical makeup of alum, I understood it to be aluminium
potassium sulphate, and if this is so, does anyone know how to obtain
it in Australia? I can readily purchase large amounts of aluminium
sulphate from agricultural suppliers, however when I look for
aluminium potassium sulphate it becomes laboratory grade and equates
to about $40 per 500gms.
Thanks for any help I can receive.
Cheers Kathleen O’Neill.
