1853 C. Goodyear Gum-elastic & Varieties I. vii. 114 Another effect yet more remarkable in the treatment of gum~elastic, is that of the sun's rays upon it. When combined with sulphur, and exposed to the action of the sun..it becomes solarized, or divested of its adhesive quality.

1855 P. J. Bailey Mystic 13 Then, solarized, he pressed onwards to the sun.

1892 Photogr. Ann. II. 74 An exposure to bright sunlight, sufficient to solarise the [film].

1950 Jrnl. Amer. Ceramic Soc. 33 257/2 From the general appearance of the glasses that were solarized in the mercury arc it became obvious that the depth of color change was slight.

1966 M. LaCour & I. T. Lathrop Photo Technol. xix. 229/2 To solarize a negative the developing process is carried on in a normal manner for about 2/3 to 3/4 of the developing time [etc.].

1868 M. C. Lea Man. Photogr. 137 (Cent. Dict.) It is a familiar fact that iodide of silver solarizes very easily.

1906 Westm. Gaz. 13 Oct. 14/2 There is a tendency on the part of the paper to solarise when printed by direct sunlight.

1955 E. B. Shand Glass Engin. Handbk. xvii. 159 Some glasses will discolor perceptibly, or ‘solarize’ when exposed to ultra-violet radiations.

1977 Jrnl. Photogr. Sci. 25 103/2 The emulsion investigated..was a chlorobromide, halide-exchange emulsion which had a low surface/internal speed ratio and which solarized readily.

1870 Eng. Mech. 18 Mar. 661/2 I..find..more than one solarised place.

1882 Nature 13 July 246 Portions of the solarised eye that had escaped the solarising action.

1890 J. Pulsford Loyalty to Christ I. 188 Much in the same way that the solarized atmosphere of our world becomes inbuilt..in the trunk and branches of a tree.

1969 Focal Encycl. Photogr. (rev. ed.) 1415/2 The solarizing exposure itself must also be sufficient. Too little leads to..only a partially solarized image with weak border outlines.

1977 J. Hedgecoe Photographer's Handbk. 278 The solarization, below, was produced by the black and white method, but with the solarized positive printed onto color negative film, using a colored light source.

1853 C. Goodyear Gum-elastic & Varieties I. vii. 112 The use of acid gas in connection with the solarizing process.

1882 Nature 13 July 246 Portions of the solarised eye that had escaped the solarising action.

1923 B. D. W. Luff Chem. Rubber i. 18 Articles made with such a composition, when exposed to the sun's rays, a process termed solarising, were said to lose their adhesive nature.

1969 Focal Encycl. Photogr. (rev. ed.) 1415/2 The solarizing exposure itself must also be sufficient. Too little leads to..only a partially solarized image with weak border outlines.

1977 R. Hattersley Photogr. Printing ii. 20 It involves exposing a print twice: once in the usual way and once with a solarizing light source after development has gone about halfway.
