Abstract: A flame photometric method to det. K₂O and Na₂O in silicates is described. The mutual effect of K and Na, a great disturbing effect of Ca, and almost negligible effect on Al at higher concns. of Al₂O₃ was detd. Fe₂O₃ and MgO up to 10-15% have no effect. The accuracy of this method is not as good as Lawrence-Smith's method but it is time saving and can be carried out with less-qualified persons.
