I remember a few weeks ago somebody was looking for pickling lime to make
kalkwaßer. Well I went to several stores tonight where I had bought it in
the past and there was none to be found. One of the managers said he hadn't
been able to get any for several months. I went to Ball's website and they
sold off their canning division to homecanning in 1993. Ball pickling lime
is not listed it appears to have been replaced by Ball Natural Pickling
Crisp which is CaCl2 according to the package. I went to Lowes and got
50lbs of limestone which is basically ground up CaCO3, CaO, MgCO3, & MgO.
I think Ball pickling Lime was pure CaO.
