description (Brief) This thing is a clock glass make from Pyrex glass. A clock glass is a round, concave glass dish offered for evaporation in chemistry. The can additionally be employed because that weighing solids and as a lid because that flasks and beakers.

In 1916 Pyrex found an additional market in the laboratory. It quickly became a favorite brand in the scientific community for its strength against chemicals, heat shock, and also mechanical stress. This object is component of a repertoire donated through Barbara Keppel, mam of C. Robert Keppel. Robert Keppel teach at the college of Nebraska-Omaha after receiving his B.S. In Chemistry native the college of California, Berkeley, and also his Ph.D. In necessary chemistry from M.I.T. The glassware in the Keppel repertoire covers the 19th and also early 20th centuries.
