    Alum is a very effective pickle when warm and I have never had any
    issues with having to use bi carb to neutrilize any acid effects as
    with sparex, sulphuric etc. As I understand Alum is a floculant
    which is used to purify water and grab hold of any impurities that
    are suspended in water. I am unsure of the science but it works very
    effectively in removing flux and I will continue to use it  unless
    an Orchidian expert out there points out that I am using something
    that is deterimental to my Customers and my health. By the way I
    heat my Alum in a slow cooker and when it cools I can grow some very
    awesome crystals. Best regards Terence M Dillon
