Bleached ceramics are produced on the basis of iron-bearing clays, and the process of its sintering is intensified. This ceramics has good technical and decorative properties, which is achieved by introducing into the mixture up to 20% CaCO 3 and 0.2% (above 100%) lithium chloride as a mineralizing additive.The science of construction materials recognizes the important role of decorative and finishing materials in creating up-to-date architecturally expressive buildings, including their interior and exterior finishing. This is true of ceramic materials that have to meet stringent requirements imposed on technical and service properties (water absorption, strength, resistance to frost, etc.) and aesthetic properties (shape, color, texture, etc.).The present study considers the production of bleached ceramic materials and products based on low-melting ironbearing clays and the intensification of the sintering process.The study was performed using clay from the Bol'-shelogskoe and Vladimisrkoe deposits in Rostov Region and the Gubskoe deposit in Krasnodar Region with different concentrations of iron oxides, with Fe 2 O 3 content equal to 3.40, 5.32, and 5.52%, respectively (here and elsewhere, wt.%).The ceramic mixtures also contained a high-calcium waste (HCW) material containing 5 -20% CaCO 3 and li-

The possibility of obtaining soft porcelain from ceramic pastes based on unenriched kaolin from the Donetsk deposit is examined. The physical -mechanical properties and whiteness of the samples obtained are determined. The dependence of the coefficient of reflection of individual phases of porcelain on the Fe 2 O 3 content is investigated.
