I'm able to paint so nice and thick with those big splodges that stay upright because I mix my own paint. I use the formula that the seventeenth-century painters used and I've added one or two things myself. A very important element is stand oil. I once got hold of a whole barrel full and I'm still using it. There are pots of it in all my studios, in New York, in Connecticut, in Monaco, and in Tuscany. [the oil had been found when an old paint shop closed down, in a] stock that had been there since the seventeenth century... I mix my oil paint with it, and I throw in a lot of eggs and some concentrated turpentine. It's as thick as homemade mayonnaise. When it dries it is as tough and hard as rubber.
