*^ate2saeg5g: PITTSBl JGH CORNING CORPO RATION ^ Hr. G. P. Bauman INTER-OFFICE CORRESPONDENCE From fi3u C. E. van Horne | Sobject: COMMENTS ON GRADE M AmOSITE FIBERS Date March 31, 1970 Dear Guy: * After examining the sample of Graoe "M" Amosite fibers, our people have ARRIVED AT THE FOLLOWING CONCLUSIONS! 3 1. The sample is definitely NOT a reasonable substitute for Graoe 0-11 FIBER. 2. Not only is the sample dusty and full of trash, but it appears to CONTAIN MANY SHORT FIBER LENGTHS AND FAR TO FEW FIBERS OF 1-l/2" TO 3n IN LENGTH. 3. Graoe "M" fibers are bluish-gray in color - not the whiter type THAT 0-11 IS. 4. Grade "M" fiber WOULD be a gooo substitute for scrap, but would CERTAINLY PRESENT A SERIES OF PRODUCTION PROBLEMS IF USED IN THE DRY BATCH WITHOUT A SUFFICIENT QUANTITY OF GOOD D-11 GRADE TO BEEF UP THE GRIND AND LAP.
