Spectrophotometric method for the determination of boron in glasses, glazes and ceramic colours
Abstract
A rapid method for the determination of boron in glasses, glazes and ceramic colours is described, which is based on spectrophotometric measurement of the boron-carminic acid complex, and interference effects by other elements present have been investigated. The method has been designed to give maximum accuracy for a spectrophotometric procedure, bearing in mind that up to 20% of boron oxide may be present and that the reagent is very sensitive.
