In addition to the
Calcium Chloride one needs some sodium and potassium chloride. and
some Strorntium Chloride hexahydrate. And I have not found a good
source for the Strontium Chloride.


BTW... even if all you can find is the calcined monohydrate versions, they
will take up their water of crystallization as soon as you wet them (along
with the liberation of a fair amount of heat), and will revert to the
hexahydrate upon re-crystalization.
