O knihe

Excerpt from The Mineral Industry of the British Empire and Foreign Countries: War Period; Borates (1913-1919)

Borax is a valuable ¿ux for chemical and metallurgical purposes. It is used in the manufacture of pottery-glazes and enamels, and as a glaze for paper and linen. It is also used in tanning and glue manufacture. Its property of adhering closely to clean surfaces of metal under high temperature and preventing oxidation causes it to be largely employed in brazing and as a ¿ux in brass manufacture. It is also used in the manufacture of soap and glass, and in numerous other ways. As an antiseptic it is used as medicine, and as a food preservative. Borate of chromium is used as a pigment in calico printing, and borates of manganese and lead as drying agents in the paint trade.
