Colloidal Chemistry in Relation to Industries

Abstract

I. WHEN the development of some branch of science reaches the stage at which a separate literature with its own terminology begins to grow up, the question of its practical utility or its value to the arts begins to be asked. Whether research has to justily itself by such directly or indirectly useful results is at least argu2ble, but it must be admitted that the question is particularly natural when raised in connection with a discipline like colloidal chemistry which is concerned, inter alia, with substances such as form the raw materials or the products of important arts, many of which, like ceramics, dyeing, tanning, the making of bread and of fermented liquors, are as old as history.
