Standard Test Method for
Free Moisture in Ceramic Whiteware Clays
This standard is issued under the fixed designation C324; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers the determination of free moisture in ceramic whiteware clays. Whiteware clays may be shipped as
a bulk shipment in lumps, a bulk shipment of shredded or coarsely ground clay, or in bagged lots of ground or airfloated clay.
Directions are given in this test method for obtaining representative samples of the clay shipment to be used in subsequent tests
for the properties of the clay in the shipment.
1.2 This standard does not purport to address all of the safetyconcerns, safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and
determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Sampling
3.1 The sample shall be obtained in accordance with Specification C332. The sample submitted for testing shall weigh not less
than 1000 g and shall be kept in an airtight container to prevent loss of water before testing.
4. Procedure
4.1 Remove the sample of clay from its container. Weigh about 500 g of the sample to the nearest 0.1 g. Spread out the weighed
portion of the sample in a weighed shallow metal or porcelain container, and dry at 100100 °C to 110°C110 °C for 24 h in a drying
oven. Reweigh the dried clay, as quickly as possible, to the nearest 0.1 g.
