Porcelain Birthday Cake Tealight. Wonderful for the mantlepiece, on the dining table or in the garden. A lovely birthday gift for the candle lover in your life! Thrown on the potter’s wheel and then pierced so that the light flickers through the tiny holes in the porcelain, this birthday cake 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.
