Natron and ash of seaweeds provided the sodium which served as the flux in all glasses till the Medieval period. Wood ashes then came into use, which changed the glass formulation to such a degree that potassium salts became the principal fluxing alkaUes. [Pg.422]

Aus l,5-Dinitro-9,10-anthrachinon wird 5-Nitro-1 -hydroxyamino-9,10-anthrachinon erhalten (s.Bd. X/1,S. 1149), wahrend bei der Reduktion mit Zinn(II)-chlorid/Natron-lauge beide Nitro-Gruppen zur Hydroxylamino-Gruppe reduziert werdcn. Nitro-aroma-ten ohne Acyl-Substituenten werden dagegen zu Anilinen reduziert (s.ds. Handb. Bd. XI/1, S. 453). [Pg.568]

Soda (composed of sodium carbonate) was acquired in antiquity either in the form of natron, or, when prepared, as soda ash. Natron is a natural mixture of sodium bicarbonate, sodium carbonate, lesser amounts of common salt, and sodium sulfate, and some organic matter. It occurs in a few places in the world, such as in dry lakebeds in desert regions, in Egypt and Siberia, for example. From these few sources, natron was traded and transported to many others in the ancient world, where it was used (von Lipmann 1937 Lucas 1932). [Pg.141]

The main source of silica in antiquity, as today, was sand and, very occasionally, crushed rock or pebbles. The most common modifier was soda, which was obtained from natron lakes, as in ancient Egypt, for example, or from vegetable ash. Most lime was derived from limestone, although some lime could also enter the mixture of glass raw materials together with soda... [Pg.154]

Secondary mineralization at Mount Keith produces hydromagnesite, while mineralization at Diavik includes carbonates of Mg, Ca and Na nesquehonite, calcite, vaterite, natrite, thermonatrite, natron, trona, gaylussite and northupite. The rate of carbon mineralization at the two mine sites was assessed using quantitative powder X-ray diffraction analysis and the Rietveld... [Pg.143]
