Abstract
A method for measuring the moisture content of a hydrous material employs the steps of determining the tare weight of a shallow rectangular sample container having a top, adding a sample to the container, weighing the sample and container, applying heat and pressure to the sample container using a pair of aluminum or graphite blocks, weighing the sample after heating, and calculating the moisture content. The method is applicable to measurements which are made outside the laboratory.

A method for measuring the moisture content of a hydrous material comprising:
- determining the tare weight of a shallow rectangular sample container having a top;
- adding a sample of material to the sample container;
- weighing the sample and sample container;
- applying heat and pressure to said sample container by means of a heating medium comprising a pair of blocks formed from a material selected from the group consisting of aluminum and graphite;
- weighing the sample after heating;
- and calculating the percentage moisture content M according to formula I ##EQU2## wherein W is the weight of the sample in the hydrous state and Wo is the weight of the sample in the dehydrated state.
