Last night I was at a party at Bill Chisholm's studio, and I had a long, interesting, and fun conversation with Steve Salek, who owns Vasari Paints.
I've know about his paints by reputation for years, but I have to admit I've never tried them. I'll certainly be putting in an order now. Sometimes business is all about the personal connection.
One of the most interesting things he said was that a knowledge of chemistry was far less important to a paint maker than a solid understanding of the physics of light, particularly it's interaction with the particles in paint. It wasn't at all what I expected, but in hindsight makes perfect sense.
