Italian burnt Sienna is prepared by calcining raw sienna and results in a warm orange-brown hue.

Note for the processing in acrylic: Terra di Siena is suitable for the use in acrylic, however we do not recommend processing this pigment with Dispersion K 52 (#75075) as it flocculates in this acrylic binder.
