For the determination of iron, titanium, aluminum and sulphate in soda lime glass by JIS, it takes several hours to follow the complicated procedures, therefore, a rapid determination method was studied.<BR>Ratio of contents among iron, titanium and aluminum in ordinally soda lime glass is about 3 : 1 : 50. Therefore, iron and titanium are determined by the spectrophotometric method with 2-methyloxin. Aluminum is determined by the chelatometric titration after iron and titanium being removed with 2-methyloxin.<BR>The determination of sulphate, being separated by cation exchange resins, is made by the chelatometric titration.<BR>The results obtained by this method are found to be accurate and rapid.
