Use of the hydrogen flame attachment and the Beckman Model DU spectrophotometer to determine potassium in soda‐lime and boro‐silicate glasses in the order of 0.01 to 2.5% K 2 O is described. Data are presented showing the effect of varying concentrations of sodium, calcium, magnesium, barium, zinc, aluminum, and iron on the potassium flame emission. The potassium emission is relatively free from interference effects except from zinc and large amounts of barium. The method is rapid, precise, and accurate to 2% of the K 2 O present in the sample.
