Phoenix, Arizona, heads the lists of plants that made Zonolite Mono-Kote fireproofing in W. R. Grace & Co.'s sworn answers to interrogatories in a 1987 lawsuit, Williams against National Gypsum.1 For each product the answers say only that it "was manufactured at some or all of the plants listed below," so they do not show that every product was made at Phoenix.1 The list for Mono-Kote MK-1 names Phoenix without dates ("Approximate dates of production are not known"); the list for Mono-Kote MK-3 gives "Phoenix, Arizona (Glendale); 1960-1973."1 The answers do not say whether Zonolite Company or Grace ran the plant; they say MK-1 was "Produced by Zonolite Company from 1959," and MK-3 by Zonolite "from 1959 to 1963" and by Grace "from 1963 until 1973."1
The same answers describe the two products in general, not Phoenix's output in particular: MK-1 as a "Cementitious light beige fireproofing material" with "approximately 11.9% short fiber Chrysotile asbestos," and MK-3 as a "Light beige cementitious material" for fireproofing, with "approximately 13.23 percent 7M" and "12.18 7R" short fiber chrysotile asbestos by weight.1 Both were packed in "multi-walled, pasted-valve bags" of kraft paper.1
