Description (Brief) This object is a watch glass made from Pyrex glass. A watch glass is a round, concave glass dish supplied for evaporation in chemistry. It can likewise be employed for weighing solids and also as a lid for flasks and also beakers. Pyrex has actually its origins in the beforehand 1910s, when Amerihave the right to glass agency Corning Glass Works started trying to find brand-new products to feature its borosteustatiushistory.orglicate glass, Nonex. At the suggestion of Bessteustatiushistory.orge Littleton, a Corning scientist’s wife, the firm started investigating Nonex for bakeware. After rerelocating lead from Nonex to make the glass safe for cooking, they named the new formula “Pyrex”—“Py” for the pie plate, the initially Pyrex product. In 1916 Pyrex discovered another sector in the laboratory. It easteustatiushistory.orgly came to be a favorite brand also in the clinical community for its stamina against chemicals, thermal shock, and also mechanical tensteustatiushistory.orgon. This object is part of a repertoire donated by Barbara Keppel, wife of C. Robert Keppel. Robert Keppel taught at the College of Nebraska-Omaha after receiving his B.S. in Chemisattempt from the College of The golden state, Berkeley, and also his Ph.D. in organic chemisattempt from M.I.T.
