THE TREATMENT OF AN ODILON REDON CHINE COLLÉ LITHOGRAPH, L'ART CELESTE
1. Friction drying was undertaken with the grain of the friction-drying papers across the grain of the object papers. The author thought that this procedure might encourage alteration in the size and shape of the paper sheets. Subsequent testing suggests that crossing the grain of the friction-drying papers to the grain of the object paper makes no difference to the stretching effect of the friction-drying process. In fact, for the mock-ups prepared, the alteration in the size of the sheets caused by friction-drying was exactly the same when the friction-drying papers were across, or with, the grain of the object. In both cases the sheet size increased by 1–2 mm with the grain, and 4–5 mm across the grain. Only one type of paper was tested. Tests were not undertaken to determine the effect of having one friction drying paper across the grain, and one with the grain, of the object paper.
