What reading level is A Manual of Fire Assaying book?
To quickly assess the difficulty of the text, read a short excerpt:
12. Na 2 O. PbO. FeO. Ca0. 4Si02 . . I Bisilicate 1100 Vitreous, black.
13. 2(Na 2 O. PbO. CaO)3Si0 2 . . . . Monosilicate. . .
1090 Stony, light yellow.
14. 2(Na20. FeO. CaO)3Si0 2 Monosilicate. . .
1150 Viscous, stony, gray- brown.
15. 2(N a2 O. PbO. FeO)3Si0 5 . . . .
Monosilicate. . .
1030 Vitreous, black.
A partial replacement of the silica by borax glass in the foregoing slags will appreciably lower the formation points.
Bases such as FeO, CaO, MgO, MnO, BaO, and A1 2 O 3 are present in g...reater or lesser quantity in almost all ores, and SiO, is present in practically every ore, so that such slags as those 1 Elmer E. West, Laboratory, S. D. School of Mines, 1904 Stony slags indicate incomplete solution of some of the ingredients.
THE CRUCIBLE ASSAY 69 outlined must necessarily be made. The easily fusible bases PbO and Na 2 O serve to lower the formation point of the slag. If it is accepted that the composition of the slag in the assay is practically the constant factor, it is evident that when the ap- proximate composition of the ore is known, we will add either basic or acid fluxes, in such proportions as to produce the proper slag decided upon.
