Instead, it came out intact, like a smooth, tough vellum paper. It stood on his desk, forming a model of the vessel which it had lined...
This happened not long ago in the chemical engineering laboratories of Massachusetts Institute of Technology, where Associate Professor Ernst Alfred Hauser and a blonde, slim young woman chemist who was his co-worker were investigating the properties and behavior of bentonite. Mined in Canada and the western U. S., bentonite is a kind of clay which has the property of swelling when it is wetted, absorbing up to ten times its own volume of water. It is used for foundry molding, in tooth pastes, face powder and facial mud packs...
Owens-Illinois and Corning are model parents for the new company.

Corning (assets and profits secret) has specialized in technical refinements; it was to Corning that Thomas Edison went in 1878 asking for a little glass bubble in which to put his incandescent filament...
...toothbrush with synthetic bristles replacing the standard hog bristles imported from northern China. These new synthetic bristles are actually coarse strands of Fibre 66, and Weco claims they absorb only 20% as much moisture and dry much more quickly than the natural variety. Developed by the late Du Pont Chemist W. H. Carothers, Fibre 66 in bristle form is called "Exton," is made by forcing through small openings a synthetic resin known as "nylon," thus producing filaments in much the same way that rayon is manufactured. Because diameter of the bristles can be regulated in production, definite standards of "hardness...
