Colorimetric Determination of Boron in Porcelain Enamel Frits
A procedure is presented for the modification of the current method of developing the boron‐curcumin color complex for a quantitative determination of boron in glass. Instead of evaporating an aliquot of the solution to be tested and baking the residue at 55°± 3°C. for a specified time with curcumin...

| Zusammenfassung: | A procedure is presented for the modification of the current method of developing the boron‐curcumin color complex for a quantitative determination of boron in glass. Instead of evaporating an aliquot of the solution to be tested and baking the residue at 55°± 3°C. for a specified time with curcumin indicator solution, the color complex is developed by dissolving a measured volume of test solution in glacial acetic acid with sulfuric acid. |
