I am not sure how to parse the sentence "[t]he difference between the properties
of TACC prepared per the low albedo books and its production is just that you
fet by mixing the chemical in water are two different products."

Have you ever read Chertier's description of how to make Chertier's copper?

It seems to me we ought to regard the inventor's description of the compound
named after him as authoritative.

Of course, NONE of the above-noted compounds are the original Chertier's copper
(chlorate de cuivre et d'ammoniac) as described by Chertier!

See Barry Bush's article previously cited to sort out all the confusion about
this chemical as described by pyrotechnic authors post-Chertier.
