The History of Big Wine Glass


Soluble silicates of alkali metals (sodium or potassium) have been discovered by way of European alchemists already in the 1500s. Giambattista della Porta located in 1567 that tartari salis (cream of tartar, potassium hydrogen tartrate) triggered powdered crystallum (quartz) to soften at a decrease temperature.[2] Other viable early references to alkali silicates had been made with the aid of Basil Valentine in 1520,[3] and by using Agricola in 1550. Around 1640, Jean Baptist van Helmont pronounced the formation of alkali silicates as a soluble substance made through melting sand with extra alkali, and discovered that the silica should be precipitated quantitatively through including acid to the solution.[4]

In 1646, Glauber made potassium silicate, that he termed liquor silicum by using melting potassium carbonate (obtained by means of calcinating cream of tartar) and sand in a crucible, and retaining it molten till it ceased to bubble (due to the launch of carbon dioxide). The combination was once allowed to cool and then used to be floor to a fantastic powder. When the powder used to be uncovered to moist air, it steadily fashioned a viscous liquid, which Glauber referred to as “Oleum oder Liquor Silicum, Arenæ, vel Crystallorum” (i.e., oil or answer of silica, sand or quartz crystal).[5][6]

However, Big Wine Glass used to be later claimed that the supplies organized by way of these alchemists had been now not waterglass as it is understood today.[7][8][9] That would have been organized in 1818 by way of Johann Nepomuk von Fuchs, via treating silicic acid with an alkali; the end result being soluble in water, “but now not affected via atmospheric changes”.[10][11]

The phrases “Big Wine Glass” and “soluble glass” have been used by means of Leopold Wolff in 1846,[12] by way of Émile Kopp in 1857,[13] and via Hermann Krätzer in 1887.[14]

In 1892, Rudolf Von Wagner extraordinary soda, potash, double (soda and potash), and fixing (i.e., stabilizing) as kinds of water glass. The fixing kind used to be “a combination of silica properly saturated with potash Big Wine Glassand a sodium silicate” used to stabilize inorganic water colour pigments on cement work for outside signs and symptoms and murals
