Printing industry annals are filled with tales of major inventions benefiting humankind. For instance, take the story of Francis E. Okie. Born in 1880 in Delaware County, Pa., Okie entered the printing ink business in the 19th century. He owned a shop at 124 Kenton Street in Philadelphia. At first, the F.E. Okie Co. specialized in lampblack inks. These inks derived their black pigments from the burning soot of mineral oils. The pigments were slow to produce, and the messy soot created a filthy environment.
Unhealthy conditions
After the First World War, the ink business had fierce competition and slim profits. Okie’s ink company wasn’t an exception. A company in the business of beveling glass for mirrors and tables shared space with Okie. Grinding and sanding glass meant the shop was always encapsulated in a massive cloud of dust.
On one visit, Okie learned the owner wanted to sell out, probably due to the unhealthy working conditions. That’s when a lightning bolt of an idea struck Okie. Why couldn’t these garnet and flint dry-grinding materials be made waterproof and used in combination with a liquid to keep down the grinding dust? Why, indeed!
Okie started experimenting with waterproof adhesives that could be applied to paper with a sprinkling of garnet on the sticky surface. Garnet proved a poor abrasive, and the correct glue formulation was elusive. Still, Okie soldiered on, experimenting with a variety of materials. Until, one day, he went searching for a better supplier of grit. On a frigid January 1920, a letter arrived at the offices of fledgling abrasives firm in St. Paul, MN.
