Deeds 8/6 Chicago Auxiliaries Hesearch August 13# 1956 Isw Jersey Grades IdthspOM men Appropoe of your nemo of the above date on New Jereey lithopone, ve should perhaps tall you that we have ordered 50# bags of the several grades of Albalith which we feel ve way be doing the moot work on for oouoteraatch purposes* These grades are Albalith 13* 73# 90# 332 and 362. In Hn with your suggestion about obtaining the characteristics of the various grades, this work is already under way. Incidentally, ve have attach*d the section on counteyvatchas for Parmallths which appears in the preeent Peraolith brochure. This lists our current nearest countermatchae for the various grades of Albalith. One additional grade of lithopone which ve have run into, but which Mew Jersey never indicated in their sales bulletins or the Pigment Index, la Albalith This appears to be an extra high consistency, low- reactivity lithopone. Apparently this la only supplied to special customers and is not oarried as a regular grade. We have Just received a 5 lb. sample of Albalith 73. A portion of this has boon submitted to Bezb Sohaars together with our Pvrmolith 60-J, as well es a sasgkla of Permolith 1|0-#V for comparative evaluation. Characteristics on other grades will be established as the material is received and we will pass the information along as it accumulates. P. C. Terduiuhb cct JVH, JBfl, Att. C. K.
