The Metals Coating Company of Philadelphia is named in the source as having cooperated with Palmer H. Craig on metal-spraying methods for preparing thin bismuth films. Metal spraying (the Schoop and Gravitas processes, with nitrogen used to prevent oxidation) was one of the film-preparation routes Craig compared with casting, electroplating, evaporation, and cathodic sputtering.
