1.1 These test methods cover the chemical analysis of clays used in the manufacture of ceramic whitewares.

1.2 The analytical procedures appear in the following order:


These test methods cover the chemical analysis of clays used in the manufacture of ceramic whitewares. Determine moisture on the sample in its ordinary air-dried condition. Determine all other percentage compositions on moisture-free samples and report accordingly on a moisture-free basis. Make blank determinations on the reagents for each constituent in the whiteware clay and deduct this blank in each case. The sample shall be heated to a constant weight at a given temperature; the loss in weight is recorded as moisture. For the determination of the silica blank, approximately 0.25 g of alumina should be added as aluminium chloride. The procedure for the determination of iron, aluminium, and titanium oxide blank are presented in details. The procedure for the determination of iron oxide, titania, alumina, lime, magnesia, and alkalies blank are discussed and presented in details.
