Porcelain Double Heart Tealight. Wonderful for the mantlepiece, on the dining table or in the garden. And a thoughtful gift for someone special. Thrown on the potter’s wheel and then pierced so that the light flickers through the tiny holes in the porcelain, this double heart tealight is then high fired to 1260 degrees. This makes the porcelain become translucent when lit from within, giving a soft amber glow and the throwing lines become clearly visible.
