The use of sinopia, a reddish-brown ochre-like earth color pigment used in traditional oil painting and so named after the Turkish city Sinop, is explored in this look at artist Fabrizio Arrigonis. Used for the cartoon or underpainting for a fresco, sinopia, which is composed of iron oxides, from a kind of clay or quartz called sinople, became a forgotten medium until the 1950s when the new technique strappo became state of the art and the old sinopias were rediscovered. Fabrizio Arrigonis sketch and notebooks refer to the old masterous techniques, which can be discovered in his drawings.
