Candle Making FAQ

Candle Making FAQ

3 mins read

Candle making has its moments of frustrations, and many of our makers have commented on the need to test and trial to get the perfect result. See some of our frequently asked candle making questions below; 

Why does my candle have cracks in it?

There are lots of variables in candle making, so as any chandler will tell you, product results can vary from batch to batch, and cracking can be a common occurrence, especially in the cooler months. The type of dye, vessel and temperature can all have an impact.

Why does my candle have white lines after it's been produced?

This can happen either when your vessel or wax is too cold. To prevent these ‘jump lines’, try warming your vessel first or pouring the wax at a slightly higher temperature.

How do I prevent air bubbles in candles?

Like jump lines, air bubbles are often the consequence of a cold vessel. Whilst it can be tricky to achieve this, heating the vessel to around 70 degrees Celsius is a great way to prevent air bubbles.

Why does my re-pour layer not blend into my first pour?

This can sometimes happen due to the second pour being too cool. If possible, aim to pour the re-pour only a couple of degrees lower than the original. 

From an appearance perspective, it’s also important to complete the re-pour layer whilst the candle is still warm and not yet fully hardened.

Why does my candle smoke while being burnt?

In our experience, this is usually due to the wick being too large or too much fragrance oil having been added to the wax. 

If you are confident that you are using the correct size wick (good melt pool, steady even flame) and have used the correct amount of fragrance oil, it may be that your wick is too long. Always ensure the wick is trimmed to half a cm tall before each burn to avoid this.

How do I keep my wick up-right while pouring?

Our adjustable wick holders are a great way to keep your wick in place.

Why is there leftover wax on the side of the container?

It is possible that the candle was not burnt long enough on its first burn. It is vital to ensure you allow the candle to burn for 1 hour per 1 inch (2.5cm) diameter of the actual candle during its first burn for a maximum of four hours. 

This will ensure the candle can burn correctly on subsequent burns, otherwise a tunnelling effect is likely to occur resulting in leftover wax remaining on the side of the container. If you are unable to achieve a full burn pool when burning for the required length of time on the first burn, you may require a larger wick to resolve this problem.
