    Hi all.  I really have been pleased using acid (pH minus) instead of
    Sparex. Thanks Orchid and John Burgess! 

    Lately though, as I've been using Prip's flux more often I have
    discovered a warm alum solution is superior for removing that
    tenacious post-Prip's glaze.  Thanks again to Orchid and friends! 

    My question concerns potential problems when using alum. 

    -Is there any difference in action or safety among the various
    "alum" compounds available? 

    -Would prolonged immersion in alum solution affect the metals or the
    solder joint?   

    -Are there conditions that would produce plating of dissolved metal
    ions?  

    -Are there metals or stones which should not be placed in alum
    solution? 

    -Any situations where acid might be preferred over alum solution? 

    In searching for a more reasonably-priced source than buying alum in
    the spice aisle, I have found aluminum sulfate, as a mordant in
    fabric dyeing, available at $2.75 / lb. and $10.95 / 5 lb from this
    website:  http://www.dharmatrading.com/html/eng/3334-AA.shtml Thanks
    in advance for enlightenment. :-) Pam Chott Song of the Phoenix
