With a brass reflector, this stove gives off no smoke or soot and can be placed wherever convenient. There is a layer of rock wool fire insulation between the reflector and the outer ceramic shell, so Piet can be placed near walls or furniture. The stove takes its name from Danish architect and mathematician Piet Hein who made the super ellipse popular in the sixties.
