The material was tested chemically with the following results:
-
(a) Obtained good positive tests for potassium, carbonate,
tartrate, chloride and sulphate.
(b) Obtained negative tests for resin and calcium. The negative
test for calcium is not conclusive proof of its absence, since
in the absence of the necessary reagent, the best test could
not be applied.
(c) The water solution was alkaline to litmus.

The material therefore probably contained the following-named
substances:
Cream of tartar; potassium carbonate; sodium chloride (common
salt) and sodium sulphate and is almost certainly impure
argol, that it to say a wine residue.

Yeast cells could not be found.
