Voltammetric methods formerly solely applied to laboratory experiments were used for measurements in a green glass tank. The applied experimental parameters had to be restricted to step times of 20 ms or more using square-wave voltammetry and frequencies of 35 s<sup>-1</sup> or lower using alternating current voltammetry. Within these limitations, the voltammetric sensor used was fairly suitable for these measurements. The adjustment of the electrode area, i.e. the dip-in length of the electrodes, could easily be controlled by conductivity measurements between the electrodes. The obtained voltammetric curves were fairly similar to those obtained from laboratory experiments and were predominantly affected by the iron concentration of the glass melt.
