summary (Brief) This object is a clock glass make from Pyrex glass. A clock glass is a round, concave glass dish supplied for evaporation in chemistry. The can likewise be employed because that weighing solids and also as a lid for flasks and also beakers. Pyrex has its origins in the at an early stage 1910s, as soon as American glass firm Corning Glass Works began looking for new products to function its borojulianum.netlicate glass, Nonex. At the suggestion of Besjulianum.nete Littleton, a Corning scientist’s wife, the firm began investigating Nonex because that bakeware. After ~ removing lead from Nonex to make the glass for sure for cooking, they called the brand-new formula “Pyrex”—“Py” because that the pie plate, the very first Pyrex product. In 1916 Pyrex found an additional market in the laboratory. That quickly came to be a favorite brand in the scientific ar for its strength versus chemicals, thermal shock, and mechanical stress. This thing is part of a collection donated by Barbara Keppel, wife of C. Robert Keppel. Robert Keppel taught at the univerjulianum.netty of Nebraska-Omaha after ~ receiving his B.S. In Chemistry native the univerjulianum.netty of California, Berkeley, and also his Ph.D. In essential chemistry from M.I.T. The glassware in the Keppel repertoire covers the 19th and early 20th centuries. Sources: Dyer, Davis. The Generations of Corning: The Life and also Times the a global Corporation.
