.SOLAR FURNACE
Generating over 1500° of heat, this sun-powered kiln will produce new and unusual fusing effects.

ONE of many unusual tasks the sun did at the recent Solar Symposium in Phoenix, Arizona, was the firing of enameled jewelry in a “solar kiln.” Far from being a mere stunt, the kiln turned out three hundred blue and gold enameled pins for the officials, and dozens of earrings, cuff-links, necklaces and other jewelry. Designed and made by the Phoenix Fine Arts Association, the jewelry, called “Solar Wrought,” brought fancy prices as something unique in jewelry. Yet the idea is simple enough that anyone can easily build his own kiln and fire similar items.
