Book of Formulas Recipes, Methods and Secret Processes Prepared by the Editorial Staff of Popular Science Monthly
|
| Introduction: I found the Book of Formulas, Recipes, Methods and Secret Processes at a public library tag sale. With a title like this and a price tag of 25 cents - who could resist? I have found the publication educational and entertaining on many aspects of life in the early part of this century, when many items were made in the home and not purchased in a store. Homemade adhesives, cosmetics, perfumes, paints and whitewashes, chemistry, metals, arts and decorations, the topics go on and on. Technical information is claimed to have come from authoritative sources at the time, including U.S. Government scientists and industrial scientists of high standing. The following glass related information is for your enjoyment. |

| "Glass is a fused mixture of sodium or potassium silicates with one
or more of the insoluble silicates with varying proportions of other substances
which produce color, or give to the glass some especial characteristic
such as certain refractive indexes or tolerance to reagents. The silicate
is derived from the sand (silicon dioxide, silica, quartz) used, and in
practice is mixed with sodium carbonate or potassium and the other ingredients,
and fused, the silica entering into chemical combination with the carbonate
or base to form the glass.
Window glass is made by fusion of a mixture of sand, sodium carbonate or sodium sulfate, and calcium carbonate (limestone) in fire clay pots. Flint and lead glass are made from ground flint, lead oxide, and potassium carbonate, with or without the addition of saltpeter, and is very fusible. Ordinary household articles such as drinking tumblers, vinegar jugs and decanters, are made from this quality of glass. Bottle glass is green due to the iron it contains, and arsenious oxide (white arsenic) is often added to counteract this green color by oxidizing the iron." |
