Lily flower with candle

What causes “mushrooming” and how do I reduce this?

“Mushrooming” is carbon build-up on the wax when a candle is burned. The main factors contributing to “mushrooming” are the choice of wick (type and size), the fuel (wax) and additives.

EcoSoya® soy waxes burn exceptionally clean. Adding scent and dye to the wax “contaminates” the combustion process of a candle. Scent and color are non-fuel sources that can collect in the wick creating the “mushroom” or carbon ball. Changing the wick, scent and dye combination will correct this problem. We recommend only using NON-cored wicks.

What type of wick should I use?

Non-cored wicks work best. Try wicks such as: HTP, RRD, CD, Eco, flat braid, square braid, hemp, wood, etc. Wick size and type is completely dependent on candle size and type, shape, scent, color and the type of burn characteristics you desire.
