Anytime you are oven drying something (at the proper temp of 230 +-9 F or 110 +-5 C), you are supposed to dry them until they achieve "constant mass". Constant Mass is defined as "the mass at which additional drying would result in less than an additional 0.1% loss in mass". In general terms, if you dry overnight as the proper temperature, that is usually sufficient to achieve constant mass.
this was a clean test , hats off

You might want to read the standard... the soil pat was not correct. This soil pat was concave. The standard states it should be a horizontal plane.
Agree. Now if only I could actually achieve that horizontal plane in practice!!
