Page "Katharine Burr Blodgett" Paragraph 8

In 1938, she devised a method to spread these monomolecular coatings one at a time onto glass or metal.

She used a barium stearate film to cover glass with 44 monomolecular layers that made the glass more than 99 % transmissive, creating " invisible " glass.

This coating is now called the Langmuir-Blodgett film.

One such use for her glass was in the stunning cinematography of the widely popular film, Gone with the Wind ( 1939 ).

The Langmuir-Blodgett trough is also named after her.

She also invented the color gauge, a method to measure the molecular coatings on the glass to one millionth of an inch.
