This section is from the book "A Treatise On Beverages or The Complete Practical Bottler", by Charles Herman Sulz. Also available from Amazon: A Treatise On Beverages.
The above engraving shows an outline of a small, but compact and complete, practical laboratory for bottlers' use, with all the necessary reagents and utensils required for the examination of water, carbonic acid gas, carbonates, sulphuric or muriatic acids, sugar or syrups, fruit acids, essential oils, drugs, alcohol, colors, etc. This is a handsome arrangement put up according to scientific and practical principles, by the author of this work, and for sale by the Publishers, at a moderate price, comprising all the principal fixtures, and pipettes, dropping and test tubes, crucible, lamp,' etc., which are required when the carbonator desires to know the properties and purity of his materials. For detecting the presence of impurities and adulterations in all the materials and ingredients used in carbonating beverages, this is a very valuable outfit.
Special directions for operating and manipulating accompany it.
Successful carbonating and the manufacture or compounding of a high-class beverage depends on the purity of the materials employed, and on the absence of adulterations, or, if present, on their detection and the proper mode of treatment to remove them, or avoid their deleterious effects in the course of manipulation.
Practical chemistry has devised various and simple methods of detecting impurities and frauds in all the materials and ingredients employed in the manufacture of carbonated beverages. It requires no experienced chemical skill to apply them. We have arranged these methods and explained them in such a way, and ficted up "The Carbonator's Analytical Laboratory" with such necessary instruments and chemicals, that will enable the practical carbonator, without being a chemist, to determine in an instant for himself the practical value of all materials and ingredients that he necessarily employs, and to decide on their merits and suitability of application, thus protecting against fraud and its consequences in employing adulterated goods.
