Temperature distribution

The flame of a candle is separated into different glowing and temperature areas, which are easily visible to the naked eye:

(1) Candle body with a liquid wax pool

(2) Wick, curved towards the edge of the flame with a glowing tip

(3) Blue zone:

  • in the lower part of the flame
  • Usually has a weak glow
  • Temperature increase due to oxidation
  • Excess oxygen

(4) Dead space:

  • 600–1000 °C
  • The fuel mass evaporates
  • Low oxygen
  • Generation and build-up of carbon particles

(5) Primary reaction zone:

  • Very hot oxidation zone
  • Temperatures of up to 1400 °C
  • Almost complete burning

(6) Luminous zone:

  • starts within the primary reaction zone and ends at the tip of the flame
  • The carbon particles glow while they are heated further,
  • they emit yellow light
  • and are burnt upon contact with oxygen.

The Wedo wick-configurator

To ensure the best possible burning results, the wick must be well adapted to the candle system in question. Our wick-configurator allows you to easily define key candle parameters – it then automatically lists a number of suitable wicks for testing.

All about wicks

Let us forget our age of high technology for a second and have a purely scientific look at the mechanics of a candle flame. When we light the wick of a candle, the heat of the flame melts the wax.

Wick positions

Ideal wick position: The wick protrudes from the candle in a straight line and bends towards the flame boundary, entering the “glow zone”, where it burns fully at the highest temperature under the influence of oxygen.
