Anyone know of a good guide to the many clarifying and fining agents out there? I know there a quite a few (bentonite, gelatin, isinglass, sparkelloid, etc). But as a newbie, I don't know when to use which, and often the best way to use them! Sometimes I see hazes, sometimes I see large particles, don't know which to use. I know I've seen a few explanations of specific ones, but bringing it all together would be nice.
