Ferruginous hematite-dominant nodules (dark color) in the Dobrčice porcellanite. A multicolored and brecciated sequence of baked clays was converted by a coal fire to yellow porcellanites with irregular nodules of dark vesicular ferruginous slags derived from siderite concretions. The variation in colors seen here are primarily because of variable iron concentrations. The Dobrčice porcellanite deposit was dated using paleomagnetic methods, and the coal fire corresponds to 3.40–2.48 Ma (Pliocene, Gauss normal polarity epoch). The temperature of combustion metamorphism exceeded 1150 °C.
