Synopsis
Excerpt from Practical Testing of Raw Materials: A Concise Handbook for Manufacturers, Merchants, and Users of Chemicals, Oils, Fuels, Gas Residuals and Bye-Products, and Paper Making Materials, With Chapters on Water Analysis and the Testing of Trade Effluents
Wherever chemicals, oils, drysalteries, fuels, or any similar raw materials of varying strength or composition are employed, the quality of the article should never be accepted on the word of the seller. Instances have been mentioned with a view to illustrating this contention, but the principle should be applied invariably wherever goods of uncertain strength are concerned. It is well known that many chemical works have two classes of customers - the people who test their goods, and the people who do not test at all. The former class gets high strength deliveries, the latter gets whatever is left. Users of chemicals, lubricants, fuels, etc., have very little idea as to the truth of this state ment. It is only when they come to apply such simple, yet reliable tests as will be found in these pages, that the situation is seen in its true light. We have nowadays continually dinned into our ears the never-ending story of German superiority in commercial matters, yet one very important factor of German commercial keenness is often lost sight of, and it is this: The German manufacturer does not take the quality of his raw materials for granted; the English manufacturer cery often does.
