NATURAL & SPECIAL PIGMENTS

NATURAL & SPECIAL PIGMENTS

Description
The range of natural and special pigments consists of ochres, oxides, earths (sienna), umbers, green and blue. These natural and special pigments originate from the erosion of various rocks in countries like France, Italy, Spain, Cyprus, and so on. The quarried rocks are washed, dried and pulverized. The main ingredient and chromatophores of natural pigments is iron oxide, complemented by several other oxides. Depending on the composition, we talk about ochres, oxides, earths or umbers. If the earths and umbers are calcinated the colour changes from yellow to reddish-brown and we speak of burnt earths and burnt umbers. The natural pigments are all in soft natural colours ranging from yellow, red and brown to black. The alkal, acid resistance, the UV and the temperature resistance are the most important parameters to be taken into consideration for the use of special pigments.
