12 Common Candle Challenges

candles in production with wick holders

Below is a list of 12 common candle challenges and where they come from:

  1. Frosting - uncontrolled recrystallization of triglycerides into an undesirable crystal form
  2. Syneresis - Droplet/pooling of fragrance from the wax
  3. Inconsistent burn (multi-wick) - each wick in a multi-wick system acts as its own energy source and does not combine
  4. Low flames - small flames from undersized wick, not enough fuel to sustain combustion process
  5. High flames - enlarged flames from oversized wick, too much fuel being drawn up the wick
  6. Mushrooming - partially reduced was molecules accumulate on the wick.  Not enough oxygen or too much fuel.
  7. Tunneling - Lack of energy/heat to melt was completely, usually caused by undersized wick
  8. Dirty wick pool - brown film resulting from fragrance incompatibility with wax
  9. Clogged wick - build up of thick or incompatible materials in the wick
  10. Curled wick - may cause wick drowning or large, wide unsafe flames
  11. Sooting/Smoking - Incomplete combustion, usually due to oversized wick, fragrance incompatability, or too much fragrance.  Too much fuel that cannot be broken down.
  12. Flashover - Secondary ignition of the wax pool caused by higher wick pool temperatures and lower fragrance flashpoints.
