This variation of the gum process was actually covered in an addendum to
Poitevin's original French patent of 1855. See my _Gum Dichromate_ book,
Chapter 1. I suspect it was a cure for which there was no real disease.
While there were theoretical advantages, in practice it was not a magic
formula that guaranteed much superior results.

Others may disagree however...
