Abstract
Samples of bulk talc (14807966) produced by the R. T. Vanderbilt Gouverneur Talc Company (SIC-1496) number one mine in Balmat, New York, were collected and analyzed for asbestos (1332214) content on December 12, 1975. Ten milligrams of each sample from seven talc suppliers were prepared and analyzed by transmission electron microscopy. Asbestiform anthophyllite (1332214) and fibrous tremolite (1332214) comprised 67 to 88 and 4 to 12 percent of the fibers present in the samples, respectively. Chrysotile (1332214) was found in trace amounts in two of the seven samples analyzed. Recommendations were made to apply asbestos warning labels to the seven bulk talcs.
