Nilsa Candle Holder - available in 3 sizes. With a tapered base & tulip style sconce, they are forged from black iron by artisan blacksmiths. To preserve the finish of the iron & to protect from oxidation & rust, the candleholders have an oil finish. One of the beautiful features of these candleholders is the patina that will develop over time.To preserve the finish: Periodically re-apply food grade linseed or mineral oil, wiping off any excess.To remove rust stains: Rub lightly with fine grade steel wool. Clean and re-apply food grade oil as needed. Excessive scouring may lighten the patina, which will darken again over time.
