I first met Brian at the Bellingham Arts Festival where he offered a hands on demonstration of how to paint the bowl and how to fire it. Lead or other metals are used as part of the glaze because of the shimmer they add and their ability to crackle or "craze", taking on the darker color from the carbon that happens later in the process.
Wide brush strokes are typically used in a more asymmetrical pattern, with colors layered on top. Splattering paint can add a nice effect on top. Any part of the vessel which is left unpainted will eventually turn black from the carbon once it comes out of the kiln.

This is the kiln with an unfired bowl on top
Once the bowl is painted, it goes into the kiln to be fired, reaching a top temperature of 1800. Time in the kiln is short, say 20 minutes, as the glazes fire at relatively low temperatures. This is a lot shorter than when I use my kiln for glass, which can take 12-15 hours! Once fired, the bowls go straight into a lidded aluminum container (for the demo, this was a garbage can) to create a reduction atmosphere which creates a luster and iridescence from the metals in the glaze when the oxygen is pulled from the glazes and clay and when there is combustion inside (i.e. flames from contact between newspaper and the bowl that comes straight from the kiln). This part of the demo was interactive for all people who made a bowl. I had the job of opening and closing the garbage can, while my friend, Heidi, had the job of covering the bowls with newspaper (and staying clear of the flames)! Next the bowls are transferred to a bucket of water to stop the process and to help clean off some of the debris before the bowls are individually washed.This was a great way to experience another form of art and also very addictive ("I know the next one could be better..."). My friend, Heidi, who lives in the city went back the next day to make some additional bowls with her kids. The Seattle area is a great place not only for viewing art but for hands on experience! Let me know what you think and if you've seen other ways to participate like this at a venue.
