The Painter’s Methods and Materials: The Handling of Pigments in Oil, Tempera, Watercolour and in Mural Painting, the Preparation of Grounds and … of Light and Colour Applied to the Ma

Excerpt from The Painter’s Methods and Materials On sitting down to write this book I found so many practical questions arising to which I could discover no answer, that I considered it necessary to carry out a series of experiments in several different directions, the results of which are incorporated in these pages. To the best of my knowledge the experiments on the transparency of pigments in different refractive media and the change in the refractive index of linseed oil in process of drying are new. In numerous other cases the statements in the text are the results of actual experiments, though no details are given. A logical order of treatment of the subject proved difficult, and cross-references inevitable. In many cases repetition was found necessary to give completeness to the particular subject under discussion and save trouble to the reader.
