Per ASTM, you can not oven dry the gypsum at more than 60C due to the hydrated water content present in Gypsum. In typical materials or soils, you run this test up to 110 C.
So my question is, how would you determine the organic content of a gypsum blended material?

Another approach is to determine the gypsum content and consider what's left....is it all organic or does it contain other soil materials.
