In 1861 he developed the ammonia-soda process for the manufacture of soda ash ( anhydrous sodium carbonate a rare chemical called natrite, to distinguish it from natural natron of antiquity ) The process used sodium chloride ( from brine wells dug in the southern end of the Tully valley ) and limestone ( as a source of calcium carbonate ).

As has been noted by Desmond Reilly, " The story of the evolution of the ammonium-soda process is an interesting example of the way in which a discovery can be made and then laid aside and not applied for a considerable time afterwards . " Serious consideration of this reaction as the basis of an industrial process dates from the British patent issued in 1834 to H . G . Dyan and J . Henning.
