Heading: Science for ceramic production

It is proposed to control the redox conditions of porcelain firing in sity (& # 171; in place & # 187;) by reflection spectra in the UV-VIS-NIR region. The difference in color characteristics of glazed porcelain has been shown to be correlated with reflection at .lambda; & # 8776; 1100 nm, which depends on the Fe 2+ / Fe 3+ ratio, mainly in the glaze composition. It was found that with an increase in the intensity of the band of the optically active center of Fe 3+ luminescence, the reflection coefficient of glazed porcelain at? & # 8776; 1100 nm
