2019-09-12/2019-09-12 - From Organ Database Builders editor Stephen Hall, September 11, 2019. — Metal refining, fabricating, and associated activities started in Granite City, Illinois (across the Mississippi river from St. Louis) before 1900. Hoyt Metal opened a metal processing business there circa 1903. Hoyt Metal later sold the operation and it was renamed United Lead. In 1928, NL Industries bought United Lead. Operation at the site closed in 1983 due to enviornmental concerns. The area around the plant became one of the Enviornmental Protection Agency superfund clean-up sites. Removal of lead contaminated soil continued at least until 2010. Hoyt Metal was a generic term for various tin alloys made by the Hoyt Metal Co. Most of these alloys were used for the manufacture of linings for machine bearings. However, Hoyt also made an alloy with coating specifically for use in manufacturing organ pipes. From Mechanical Music Digest (Thursday 21 May 1998) "Hoyt metal -- two ply, tin coated, 84% lead, 10% tin, 6% antimony" [two ply refers to the tin coating] and "Hoyt metal is used in organ pipes... because they look like they have been nickel plated." . 'Mechanical Music Digest' (Tuesday 26 May 1998) suggests that Hoyt metal was made by a cladding process involving hot rolling. A book by George Ashdown Audsley on organ construction [The Art of Organ Building] (1905) gives a favorable reference to Hoyt Metal as a material for the Aeoline portion of organs. In a reference to 1920s Wurlitzer organs "The Harmonic Tuba of Hoyt metal was actually cheaper and used less lead than the Tuba Horn."
