It is proposed that the redox conditions for firing porcelain be monitored in situ (‘on site’) according to the reflection spectra in the UV-VIS-NIR region. It is shown that the difference in terms of the color characteristics of glazed porcelain is correlated with reflection at λ ~ 1100 nm, which depends on the ratio Fe2+/Fe3+ predominantly in the composition of the glaze. It was found that as the intensity of the luminescence band due to the optically active center Fe3+ increases, the reflection coefficient of the glazed porcelain at λ ~ 1100 nm also increases.
