Actually, Niepce created photographs using light-sensitive paper of his own
manufacture, and Fox-Talbot used paper soaked in silver chloride to create a
paper negative and then contact-printed the paper negatives onto
photosensitive paper. Those were his Calotypes, patented in 1841.

So it would have been more than possible for someone in 1851 to be aware of
Fox-Talbot's calotypes, and Niepce's status as the inventor of the first
photograph was probably as well-known. Artists of the day were very aware of
"developments" in photography.

Daguerre's images were created on silver-plated copper that was treated with
silver iodide and developed using mercury. Glass came into use around 1851
when Archer developed the wet collodion emulsion that was spread over sheets
of glass.

Daguerre shot on mirrored metal plates, not glass.
