Experimental study of historical processing of cobalt arsenide ore for colouring glazes (15-16th century Europe)
Cobalt was used since the early antiquity to tinge glass and glazes in blue. The presence of arsenic in blue decorated glazes since ~1500 onwards and absence beforehand, observed in Europe, might be related to the processing of the ore: roasting of the cobalt mineral (saffre) and obtaining a glass adding sand and potash (smalt) or as by-product of other metallurgical processes, e.g. silver smelting slag. We have replicated the roasting of cobalt …
Technological implications of neo-formed hematite crystals in ceramic lead glazes
Hexagonal neo-formed crystallites have been observed in thin section of different medieval and post-medieval lead-glazed ceramics. Although they are clearly visible in thin section using plane polarized light, their plate shape makes them barely seen on the polished cross sections. Basal sections have never been found on the polished sections and only few transversal very thin sections could be seen. In this case, the morphology resembles acicula…
