That depends on who and what you are making the candle for. Some people prefer candles that are made from natural, renewable sources. Others are more concerned with aesthetics. You need to decide who you are making candles for and why.If it doesn't matter what the china handmade candles factory is made from, then paraffin is the way to go. It is by far the least expensive of all the waxes. However even with paraffin you will generally pay more for higher grades. Which means the paraffin has gone through a more intensive refining process and it will have a better chance of burning cleaner than the lower grade.Paraffin wax users seem to have fewer problems finding suitable wicks for their candles. The wax doesn't have the viscosity of palm wax for example. Viscosity is the hardness of the wax. Which can be both good and bad depending on what you are going for. Some people believe that natural wax candles burn cleaner than paraffin candles. I believe that's still up for debate in the candle making industry. However, we have found by burning the different candles that we have made in our workshop plus burning many of the competitor's candles, we get the cleanest burn from palm wax candles.We found in our trials that paraffin candles contributed the most soot, followed by vegetable waxes with paraffin added, soy candles and the cleanest burn from palm wax. But again, it depends on how the wax is refined. We have received some pretty nasty palm wax, a candle maker's worst nightmare to say the least. So if it is quality you are looking for than you will most likely pay more for the wax.If you are making pillar candles and you want the pillar to burn so you can visually see its flame, then don't use palm wax. Palm wax creates a hurricane effect with pillars, or at least it should. There should be at least 1\/4 of an inch of wax that is not melted when the candle has been burned for about 4 hours. A palm wax candle can't be cupped like a paraffin candle.
