Bleininger, Albert, b. 1873, Moore, Joseph Kennedy, joint author · [Urbana], The University · leaf 35
NGES similar points in the porosity curves, we are led to theconclusion that certain phenomena are taking place. Thetechnical side of the vitrification progress is represented,of course, by the porosity curves. In Fig. 15 the action of 6and 9.5% respectively of whiting is shown for the… … 1= 90.5%KA0LIN-9.57oWHITINGZ * fl+.0% >> - 6.0%) 3.1 2.7 < a:o 2.3 1.91.7 03 06 03 Oi 2 + CONES Shales. In the porosity curves of mixtures of Hantonshale, Fig. 16, and whiting we observe that the lime beginsto act as a refractory substance in percentages that varywith the temperature. In…
