Like most products on the market, there are various grades of quality. With wax the quality refers to the oil content. The oil content also determines how long the candle burns. Although we can’t give you exact burning time figures (as the mold size, wick and environment affects it), the most ideal wax we found to use is Paraffin wax.
Paraffin wax isn’t harmful so it’s ideal for restaurants. In addition to that, its proven to last longer than palm wax and M3E.
If you want to take it one step further, consider Soy wax. Although its more expensive, it’s the perfect option to reduce your carbon footprint.
