Synopsis

Discover the chemistry behind painting with lakes and how to use them for lasting color. This practical guide introduces lakes, the color products made from natural dyes and coal-tar colours, and explains how artists and makers can create stable, vivid pigments. Learn what makes a lake durable, how fineness and the mixing process affect performance, and why testing under real-use conditions matters.

This edition translates early 20th‑century techniques into clear, usable guidance. It shows how lakes are formed, how different mordants influence hue, and how the choice of base and vehicle can change a colour’s body and longevity. You’ll find practical explanations of testing methods, quality control, and the subtle factors that prevent color shifts over time. The material is presented in a steady, approachable way, suitable for artists, restorers, and students seeking a grounded understanding of paint chemistry without unnecessary theory.

• How natural and coal-tar dyes are turned into lake pigments and how bases affect shade and stability


• How to test pigments, ensure uniform batches, and judge fineness for durability


• Practical notes on using lakes as transparent glazes and their interaction with white undercoats


• Real-world cautions about fading under light and air exposure and how to counteract them

Ideal for readers of introductory chemistry, pigment making, and artistic painting who want a clear, hands-on understanding of lake pigments and their applications.

A propos du livre

Présentation de l'éditeur

From the INTRODUCTION.
This little work is the outcome of a series of lectures delivered to a class of Practical Painters and Decorators at the Darlington Technical College. The majority of the students could not be accused of possessing even a most elementary knowledge of chemistry, and further inquiries have shown that such is the condition of affairs amongst painters generally; although, of course, there are notable exceptions, which serve to "prove the rule," as the saying is. The appreciation with which these lectures were received encouraged me to publish the same in book form, in the hope of appealing to a much larger circle, and of thus creating a wider interest in the subject.
It is all very well to tell the youthful painter that cadmium yellow may not be tinted with white lead, and that it is unwise to mix together Prussian blue and lime; but he is very liable to forget such rules until he has learned their force by bitter experience. If, however, he is made to understand why these pigments are incompatibles, his interest is awakened and the subject presents itself to him in an entirely new light. Now, this can only be done by a judicious inclusion of chemistry into the curriculum of the painter.
But the very name of chemistry is enough to frighten many practical men, for the simple reason that the majority of chemists will persist in laying such stress on symbols and formulae, atoms and molecules. The consequence is that, before the student can begin to acquire a really practical and useful knowledge of chemistry, he has to wade through and memorize a number of (to him) dull and isolated facts, which might well be left out altogether, or at any rate reserved until the student has reached a more advanced stage. As the practical man has neither time nor inclination to do this, he not infrequently leaves chemistry severely alone, and therefore fails to appreciate its value and importance.
It has been my endeavour, therefore, to show that a very thorough knowledge of the chemistry of paints may be acquired by the average student, without even a mention of such things as symbols, formulae, atomic weights, and the like; but for the sake of those who may wish to pursue any branch of the subject further, references are given, whenever possible, to more advanced literature and to original papers. Many well recognized tests for pigments and liquid vehicles are included in the various chapters, and will, it is hoped, prove of service to manufacturers and colour mixers. Should this work fall into the hands of the expert chemist, I trust that its pages will not be found altogether devoid of interest even for him.
It is at once my duty and pleasure to acknowledge the very kind assistance rendered to me by my friend and colleague, Mr. William Davison, who has patiently read through this work both in manuscript and in proof, and has made numerous useful suggestions, at the same time correcting many errors. Although I can scarcely hope that the book is, even now, entirely free from error, I believe that any inaccuracies will be of a relatively unimportant nature, for every endeavour has been made to consult the best authorities, and to include the newest and most reliable work.
