1844 R. Hunt Res. Light 106 It has been found that the fluate of soda has the property of quickening the sensibility of bromidated papers to a very remarkable extent; and from this quality a new process, which I would distinguish by the name of the Fluorotype, results.
1894 E. L. Wilson Cycl. Photogr. 159/2 Fluoride of Bromine... It is formed in the preparation of the solution for the fluorotype.
1955 H. Gernsheim & A. Gernsheim Hist. Photogr. iii. xi. 124 Fluorotype derives its name from the fluoride of sodium used in preparing the paper... The exposure was only half a minute and the picture was developed with protosulphate of iron.
