Description (Brief):

The retort was made by Schott & Genossen. Retorts are among the oldest forms of glassware used in chemistry. With their bulbs and long necks, they are suitable for distillation—the separation of one material from another through heating. The bulb containing the sample is heated and the resulting gases travel along the neck to a second collecting vessel.

Description (Brief)

Glastechnisches Laboratorium Schott und Genossen (Glass Technology Laboratory, Schott & Associates), later the Jenaer Glasswerk Schott & Gen. (Jena Glassworks, Schott & Associates), was founded in 1884 by Otto Schott (1851–1935), Ernst Abbe (1840–1905), Carl Zeiss (1816–1888), and Zeiss' son Roderick.

Description (Brief)

In 1881 Schott, a chemist from a family of glassmakers, and Abbe, a physicist with an interest in optics, formed a research partnership. Together they hoped to perfect a chemical glass formula for lenses in optical instruments like microscopes and telescopes. Their original goal was to develop glasses of high quality and purity with consistent optical properties. As their research expanded, they eventually developed the first borosilicate glasses. Their strength against chemical attack and low coefficient of thermal expansion made them better suited to the harsh circumstances of the chemical laboratory than any other glass.

Jena Glass quickly became a success among the scientific community, widely considered the best on the market until World War I.

John Christian Bailar Jr. (1904–1991), a chemist with a more than sixty-year career at the University of Illinois at Urbana-Champaign, donated this retort. Bailar helped usher in the post-World War II renaissance in inorganic chemistry and has been called “the father of American coordination chemistry.” Coordination chemistry focuses on molecules with a metal center, bound to atoms, ions, or molecules that donate electrons to the metal.
