Buying efficiency is a mighty fine thing, but there is such a thing as misdirected efficiency. If your dealer advertised card mounts at so many dollars per thousand it wouldn't mean anything to you unless you knew all about those particular mounts.And if you were to have Acetic Acid offered to you at a very low price it wouldn't mean anything to you if you did not know before buying whether it was commercial. 28%, 56%, 80% or 99%.

You do not buy efficiently unless yon know the real value of the article in proportion to its cost. Otherwise you are buying pigs in pokes and taking a chance on their coming out whole.The particular buying we are going to refer to is the buying of chemicals. The dangerous thing about such buying, strictly on a competitive price basis, is not so much the first loss, which may not readily come to light, but the loss which may come when something goes wrong.

Something is sure to go wrong, sooner or later, when a chemical is used in compounding a photographic formula and that chemical does not do its part towards making that solution function properly.

The loss then becomes a loss of all of the chemicals in the solution; the loss of materials that are being treated by the process; the loss of time in doing the work over and quite often a loss of business resulting from poor work delivered, if the trouble has not been detected before the work gets out of the photographer's hands.

There was a time when the sodas most commonly used, sulphite and carbonate, were sold in crystal form. These have been replaced by sodas in which the water has been removed, (desiccated), and no one would think of paying twenty-five or thirty cents a pound for a crystal soda. Such a price for a single pound of dry soda, however, would parallel a price of ten cents for a crystal soda provided the dry soda contained 95% or more of the pure soda.

But there is a considerable difference in dry sodas aside from the difference in price. If you bought sodas in car load quantities it would be folly to buy on a competitive price basis with no thought of the purity of the soda itself.

Suppose you were quoted a price of ten cents per pound for a 98% pure Carbonate of Soda against a price of nine cents for a 70% pure soda, which would be the best bargain?

It is quite plain that the chemical of greatest strength and purity would offer the greatest economy, for a smaller amount would be required to produce a given result. If the weaker soda were used without increasing the quantity called for by the formula, one of two results would naturally be expected: - either the solution would function improperly to the detriment of results, or the solution being weak in one or more of its ingredients would not have the lasting quality that would be expected of it, which would result in its ceasing to perform its proper functions in a shorter time than if pure chemicals had been used.

We have in mind a specific case in which the most common of all photographic chemicals, hypo, was bought on a price basis with the result that a very inferior grade of this chemical, which was never intended for photographic use, was put into fixing baths.The result was an enormous loss - a loss much greater than could ever be made up by the slight difference in cost between good and bad hypo. Hypo is used in great quantities in the tanning industry, which uses a very cheap and inferior grade of the chemical unsuited for photographic use.

It is not likely that many photographers will buy inferior hypo but there is a greater danger with other sodas which are equally important to good photographic results.

The reason for Eastman Tested Chemicals is a very obvious one. If your results are not what they should be, if you are having trouble that you are unable to locate, it is most quickly found by the process of elimination.

A demonstrator will make up fresh solutions from tested chemicals to eliminate uncertainty. His method of manipulation will eliminate other uncertainties and the trouble he is trying to locate will usually be quickly found. Most often it is found to be a matter of poor chemicals.

It is immeasurably more profitable to base the purchase of chemicals on quality rather than price - to be certain of results and rid of the annoying difficulties that are constantly arising when the strength and purity of chemicals are unknown quantities.
