Ceramic vessel 5 close to grave 233. Cemetery of La Noria.

Ceramic vessel 5 close to grave 233 (burial mound H) of the Iberian cemetery of La Noria (Fuente de Piedra, Málaga, Spain). Oxidising atmosphere. The red decoration is manufactured using hematite (Fe2O3).
The origin of the black color is an oxide of manganese identified by MRS as jacobsite (MnFe2O4), bixbyite (Mn2O3) and/or hausmannite (Mn3O4). The presence of bixbyite and/or hausmannite would be a consequence of the transformation of the most common manganese ore, pyrolusite, when the firing temperature exceeds 450ºC and remains below 900ºC.
The appearance of Jacobsita would mean that the firing temperature has reached 900 °C and that the transformation of all types of manganese oxides into jacobsite is beginning.
