Glass Sample Received from the Air Force Examination of the subject sample indicated that the largest f'ra~nt possessed both a blown surf'3.ce and a molded surface which as crackled. Since these two surfaces were opposite each other, the ~edge-shaped area between these surfaces represented the thick- nes s of the original sam?le. Tais thickness varie d from 1/2'' to 3/4''. Generally speaking, the molded surface of these fragments was practically identi cal to the crackled surface of t he botton of large rboys, acid bottles or the 5 gallon wide- mouthed jobs currently sold for ''Gardens in Glas3, In addition to the raised crackle lines, definite depressed lines or crevices 'Jere also present. tiJicroscopic e.."{a.mination indicated tha"t. these lines or crevices were shear marks. Therefore, the ware wae made frcm a sheared gob. nsidering the foregoing characteristics, it appears that the glass fra~nts may have ori3inated from one of the l a r ger carb~J3 or wide mout~ jars having capacities of 5 or 6-1/2 gallons. Also, evidence of a slleared gob would indicate that the uare was machine believe that our Alton Plant is the only plant having the necessary machinery to do these large jobs. Therefore, it is quite possible that the glass $ample represents Alton flint composition. E:n~rsion in mooochlorobenzene indicated that the glass :fraglllents have a retractive indax similar to ordinary soda-lime-silica glasses. On the baais of the foregoing information~. it appears that a chemical analyais is not necesS~J. Therefore) the sample is being returned with this correspoodence. E. C.
