Abstract
Abstract THE SURFACE OF A CANDLE MADE FROM STEARIN, PARAFFIN WAX OR THE LIKE IS DECORATED BY COVERING THE SURFACE WITH A FAT SOLUBLE DYE MIXED WITH A VOLATILE SOLVENT SUCH AS TURPENTINE; AND THEN HEATING THE SURFACE LOCALLY WITH A SOURCE OF HEAT SUCH AS A FLAME SO THAT THE DYE GOES INTO THE MATERIAL OF THE CANDLE, WHICH IS LIQUIFIED AT THE SURFACE, WHERE IT FLOATS, WHILE THE VOLATILE SOLVENT IS DRIVEN OFF. WHEN THE SURFACE OF THE CANDLE IS HARDENED, IT CAN THEN BE POLISHED.
