Brown layer after burn

[Guest Amy Moret]

Hello.. i’m new to gel candle making. I seem to be getting a brown layer after my gel candle ha burned. Any idea why? Is it the FO.. the wick? I use a wood wick

Wood wicks often release tannins into the melt pool. That would be my first guess in this case.

Vanilla fragrances can do this as well.

I thought that too so i tried a zinc wick.. Same thing! I think it might be the FO. I use oils that are 0% V but it’s still happening

Could also be oxidation from too hot of a wick for the wax blend.

Zinc wicks usually work well since they are said to burn cooler.  I think it might be better to use a container that doesn't narrow at the top too.  Are you using a non-polar fragrance oil?
