Can you use Alum to clarify stock. Similar to a swimming pool. Of course you would discard the bottom. Is it usable? Will it affect the flavor?

Alum is used for some older canning and preservation techniques, mostly pickles, but they've fallen out of favor for other preferable methods in general. As a flocculant it does have some interesting properties. I think the astringency factor and metallic flavors are what make it unacceptable for other food use.
