Ms. Kazazian Cyprus Industrial Minerals Company 24~5 Military Avenue Los Angeles, CA 90071
Dear Ms. Kazazian:
I have completed my electron optical analysis of a sample of Talc #1 submitted under P.O. #28876.
The sample was analyzed by transmission electron microscopy and selected area electron diffraction. The fibers seen in the sample as per your photomicrographs were determined to be talc ribbons. They gave a non pseudo-hexagonal electron diffraction pattern because they were standing on edge. The normal basal reflections give the pseudo-hexagonal pattern.
Thank you for consulting McCrone Associates. Please contact me if you have any questions.
Sincerely,
~A,1ft.,~

Dear Ms. Horning:
I have completed my asbestos analysis. of a talc sample submLi.tted under purchase order #28841.
The sample was examined with the transmission electron mi.croscope.. The. analysis utilized Selected Area Electron Di.ffraction (SAED) and Ene.rrggy Dispersive X-ray Analysis (EDXRA). 'The sample contained no asbestiform minerals. The only particles wwii.tth aspect rati.os higher than 3:11 were talc ribbons.

Dear Mr. Brook:
Confirming our telephone conversation concerning the Continental Minerals phone call (Mr. George Jennings), attached is a copy of the information that was passed to our salespeople. In addition, I have attached a copy of our laboratory report #80-020 in which we agree with your findings.
Our marketing strategy is a simple one j whenever a c'ustomer has doubt concerning the mineral composition of a product we offer them the opportunity to send the sample in question to a qualified analytical lab for' analysis at our ' expp~ennssee.. We feel McCrone Associates, Inc. is such a qualified organization.
Sincerely,

Dear Mr. Blashka:
We have completed our examination by transmission electron microscopy and selected area electron diffraction of the talc sample C-Z, Camas which you submitted for determination of asbestos content.
The sample was prepared by suspending a small portion of the powder in ethanol and ultrasonerating, to break up any aggregates. A small drop of the suspension was then placed on a previously carbon coated transmission electron microscope grid and allowed to dry. This grid was then examined in the transmission electron microscope.
.".;. During this examination particles with a fibrous morphology r that is an aspect ratio greater then 3:1l,,''wweerre examined by selected area electron diffraction to determine their crystallography. Based on this selected area electron diffraction it was determined that a proportion of the sample consisted of a fibrous amphibole, tentatively identified as tremolite, 'and that this proportion was less than 10%.
It should be pointed out that fibrous tremolite is defined in the Federal Register as asbestos, and that for the purposes of this definition a fiber is defined as a particle having ~ aspect ratio greater then 3:1, that is a length to width ratio of greater then 3:1. The tremolite particles observed in your sample, therefore, would be classed under existing OSHA regulations as asbestos. '
Thank you for consulting McCrone Associates. If you have any questions concerning this report please contact us.
Yours sincerely,
Richard M. Ellis, Jr. Research Microscopist

Scanning Electron Microscope (SEM) study of "Cyc1osorb" talc sample, revealed the presence of fibrous minerals. The fiber particle population density was estimated to be about 5%, however, weight percent from XRDO indicated 3% Tremmoo1lite. Microscopic study revealed that the majority of the fibers present were asbestiform. Transmission Electron Mircroscope (TEM/SAEOD) confirmed the presence of asbestiform

CONSULTING: ULTRAMICROANALYSIS MICROSCOPY SMALL PARTICLE PROBLEMS SOLID-STATE CHEMISTRY
11 March 1980
Mr. Joseph Blashka Crown Zellerbach Camas, Washington 98607 Dear Mr. Blashka: I have completed my asbestos analysis of talc sample C-Z, Camas. The sample was examined using transmission electron microscopy (TEM) and selected area electron diffraction (SAED). The sample was found to contain amphibole fibers, probably tremolite. The amount is less than 10%. Thank you for consulting McCrone Associates. Please call us if you require further information.
'If!!Sincerely yours,
