Clouds Over Campus

After lab work and before the rain I made this painting real quick just outside of the PERFORM Centre looking at the AD building of Loyola campus. The clouds were particularly interesting, they were tall billowing storm clouds with a neutral shade of blue-violet. The mix is indo blue (PB60), caput mortum (PR101), and a touch of carbon black. The caput mortum settles out due to its density giving the clouds a warm glow. Caput mortum is a paint I got recently, it is made by Sennelier the French independent paint maker that I once visited in Paris. The paint is also sold by Da Vinci company, they call it violet iron oxide. The paint is similar to other iron oxides but they heat it more so to drive off the water complex, leaving nearly pure iron oxide. Then there is mars black (PBk9) which really is pure iron oxide and even has magnetic properties that create an interesting texture. I have a natural PBk9 from Stoneground paint company and it is very nice to paint with, as I blogged about previously.
