FAQ: Why does my candle have a wet spot?

Posted on March 29, 2016

Quite an unusual term for a candle problem but never-the-less it is a legitimate term. A wet spot refers to the patch on your glass that almost looks like an air bubble between the wax and glass.

What in fact has happened is the wax has pulled away from the edge of the glass. Once this happens it will not re-adhere. It does not affect the performance of the candle in anyway. It is an aesthetic thing only.

This issue occurs when the candle temperature fluctuates and the wax expands and contracts. You will find in most cases, it will happens overnight if you leave your candles out to set.

It can be controlled by using a good quality wax like GW 464 that has great glass adhesion but also with your pour temperature.

If you find your candle wet spots as it is drying, try increasing the pour temperature.
If your candle wet spots overnight make sure you put the candles in a warm place, don’t leave them exposed to the cold.

Sometimes however, no matter what you do, you will not prevent wet spots. The climate changes both outside and inside, even during transportation or the air-conditioning in a shop can all cause wet spots.
