The lumps were quite large for a pigment bought by weight, some even larger than a walnut. On the surface, sanguine seems inaccessible because it is as hard as rock. However, all it takes is a stonecutter’s hammer and the crushed lumps become lumps, rubble, aggregate, sand and finally dust. Now more gritting, oil, gritting, oil, until it’s done. But what is all this for?
This grinded piece of rock is now transformed into a blood-coloured, sanguine butter straight out of the Italian Renaissance… Now all that is left to do is to combine it with the binder and the grinded paint is ready for painting.
