Tuscan Red is dark red with bright cherry tints when mixed with white or applied thinly. It consists of equal parts by weight of hematite (red iron oxide) and terra alba (calcium carbonate) and a small amount of alizarin. Uebele provides the recipe we used of 15 parts by weight of alizarin combined with 36 parts by weight each of hematite and terra alba natural minerals and mixed with 15 parts by weight of linseed oil.
