Abstract
Forty three samples of Kanwa were analysed for their
sodium and potassium content using flame photometry and
atomic absorption spectroscopy. Both methods gave similar
results; the samples showed about 30% of sodium and 0.1-4%
of potassium; a few results were outside these ranges. The
anions, carbonate, chloride and sulphate were detected in
the samples; sulphide was not indicated in any sample.
In the brightly coloured samples, sample nos. 5, 13, 28,
29, 38, and 40, manganese was detected and determined by
the ammonium persulphate oxidation method. The proportion
of manganese in these samples was of the order of 10
