Where to buy Alum Powder in your country?

[罗雁 LuoYan]

Alum powder is widely used for Chinese painting/ calligraphy and it is an important material for mounting. However, it is not economic to buy it from China and ship it internationally to my address. Where can I get it easily and economically?

In Germany one can get alum from any local pharmacy. It is called by chemical name: Aluminiumkaliumsulfat Dodecahydrat (Alumen).

I bought the smalled unit at 100 grams.

It seems powdered alum for paper treatment is available at good prices in the US. Here is one example product:
