One of my favorite pictures! These are dried paint pigments from Zecchi Art Store in Florence, Italy. I can still remember standing at the counter this past summer marveling at the many hues and asking what each one was made from. From herbs, to minerals, to berries, and much more...adding these powdered pigments to oil creates oil paint and is the way great Master's used to make their paint! Legend says that Michelangelo bought some of his art supplies from the Zecchi family.
