summary (Brief) This object is a clock glass make from Pyrex glass. A watch glass is a round, concave glass dish provided for evaporation in chemistry. It can additionally be employed because that weighing solids and also as a lid for flasks and also beakers. Pyrex has actually its beginnings in the early on 1910s, when American glass company Corning Glass Works started looking for brand-new products to feature its borohistoricsweetsballroom.comlicate glass, Nonex. At the tip of Beshistoricsweetsballroom.come Littleton, a Corning scientist’s wife, the firm began investigating Nonex for bakeware. After ~ removing command from Nonex to make the glass for sure for cooking, they named the new formula “Pyrex”—“Py” for the pie plate, the very first Pyrex product. In 1916 Pyrex found another market in the laboratory. It quickly ended up being a favorite brand in the scientific ar for its strength versus chemicals, thermal shock, and also mechanical stress. This object is component of a arsenal donated by Barbara Keppel, mam of C. Robert Keppel. Robert Keppel taught at the Univerhistoricsweetsballroom.comty that Nebraska-Omaha ~ receiving his B.S. In Chemistry native the Univerhistoricsweetsballroom.comty the California, Berkeley, and his Ph.D. In necessary chemistry from M.I.T. The glassware in the Keppel repertoire covers the 19th and also early 20th centuries. Sources: Dyer, Davis. The Generations that Corning: The Life and Times of a worldwide Corporation.
