B. L. Ingalls to H. B. Rhodes Transmitting the RG-244 Quality Control Study, with Appended Commentaries (1974)

A July 11, 1974 internal cover memo from B. L. Ingalls to H. B. Rhodes transmits his June 27, 1974 interim report on quality control of RG-244, the silica-treated Calidria asbestos product. The report covers wet-end testing at the King City plant and in the Niagara Falls laboratory. It concludes that the feed to chemical treatment was inadequately prepared and recommends better refining, classification, sampling and maintenance. Tabulated data, test procedures and four commentary letters and memos from Woolery, Skvarla, Byrne and Dickson are appended.
