"The first printing of a photographic image on a ceramic surface was undertaken by Lafon de Camarsac in France, 1854, using a gum bichromate system. This relied on the light sensitive chemical potassium bichromate. Mixed with gum arabic, and a sticky substance like honey, it was coated onto a ceramic surface and exposed to light through a positive transparency. Where light hit the surface of the tile, it fixed the gum; where it was darker the substance, remained proportionately sticky to the amount of light falling onto its surface. The result was a latent photograph, revealed when ceramic pigment was dusted onto its surface. Where gum has hardened no pigment adhered, but pigment did adhere to those areas un- or under-exposed. It appears that he also used a system where ceramic pigment was mixed into the light sensitive emulsion. In 1868 Lafon de Camarsac was marketing a system of producing portraits on porcelain, and although a number of companies were said to have taken up the system, it was one requiring a degree of skill to work effectively and consistently; and it wasn't one for mass industrial use." p. 29 Scott, Paul.
