Burning Instructions: For optimal performance, allow the first burn to cover the top fully. Always burn candles on a heat-resistant surface and never leave them unattended. Keep wicks trimmed to 1/4 inch and avoid drafts. To prevent tunneling, burn a candle for at least one hour per inch in diameter (e.g., 3 inches = 3 hours). If the jar gets too hot, extinguish the candle.
