Re: Gum & the commercial ?
Yes, there were commercial gum papers. Formulae were secret but these ingredients have all been suggested to have been in the mix: gum, gelatin, fish glue, glucose, sugar, honey, albumen, starch (possibly chloral hydrate or acetic acid to allow cold dev of gelatin) and Artigue was thought to have been pigmented in a powder box. Artigue paper seems to have been first mentioned in the BJP, one source says around 1884 in existence but elsewhere it says 1894. It was supplied unsensitized, and the worker had to sensitize with brushing pot bi on the back, or immersion. A guy named Blair also produced some, as did James and Saxon in 1898ish, then Mr. Johnson's Autotype paper, Richmond Gum Paper of Paisley around or before 1906, then Croft's gum paper of 1906...Artigue's was definitely the most often mentioned by far.

Yes, in the first couple of decades of the 19th
century there were many commercial gum and direct
carbon papers, including Hochheimer, Papier Noir
Gomme, Charbon Velours, Fresson, etc. The exact
ingredients of these papers is not know but it is
though that most contained gum along with another
colloid, probably gelatin.
