Candles made with gel perform much differently than those made with paraffin. Please review before use (see safety factor sheet). Testing for proper wick size is strongly recommended. Working and burning temperatures for this product is much higher than for paraffin wax. All applicable safety procedures should be maintained. All manufacturers of gel candles should consider using wick assemblies with a neck height of at least 6 mm in order to firmly hold the wick in place and keep the flame from reaching the very bottom of the candle container.
