Muurla's paraffin candles are formed concave, which allows the heart of the candle to burn straight down without melting the outer surface. The decorations on the candles are printed on a special paper, which is then placed by hand around the candle. After that, the candle is dipped to paraffin to create a layer that holds the pattern in place. In the final product, the candlelight glows softly through the whole pattern, creating a lantern like appearance.
