On this page we will try to cover some of the most common questions and add to it as more arise.
 


HOW MUCH WAX DO I NEED?
 
It is always a good idea to calculate wax usage to avoid wastage which is a very easy thing to do. All you need to know is the liquid capacity of your container or mould. You can then convert this to grams. So if your glass, jar or mould holds 175ml of water, it will take approx 175grams wax and so on. Multiply by the number you wish to fill e.g 10 x 175grams = 1750grams of wax needed.
 


WHICH WICK SIZE?
 
Finding the exact wick size for your project is always going to be the trickiest part of the process. If you need to get a really good result, the only real way is to test the wick and keep a record so you can refer back to it.
 
The basics are that wicks are sized to fit the "width" of the candle at the widest part. The height of the candle has no bearing on the wick size as any wick can be simply cut to length. You are trying to achieve a good even burn across the top of the candle to avoid the candle burning down in the middle and leaving lots of wax on the outside.

Imagine putting a tealight size wick in a 3" candle. All you will get is a tealight size hole down through the middle. This is called tunneling and is something you are trying to avoid.
 
All of the wicks have size guides which are calculated on an unscented plain candle. Once anything is added, you usually need to increase the wick size and each wax, fragrance and colour combination could require a completely different wick even if you are using the same size container or mould.

 

WHEN DO I ADD FRAGRANCE AND HOW MUCH?
 
Fragrance is generally added at 5-10% of the wax amount and we personally think 10% is probably better. So for a 150ml candle we would recommend adding 15ml of fragrance oil. There is little point trying to add more as it will just "sweat" out.
 
There are products that you can add to the wax so that you can increase the fragrance load for triple scented candles such as Bipol-X or Vybar which can be found on the
wax additives/hardeners page.
 
Fragrance should be added to cooled wax, around 60
-65°c, just before pouring. Never add to hot wax otherwise it will burn off. Always make sure the fragrance oil is stirred thoroughly into the wax to avoid wax pools.

 

WHY HAS MY CANDLE DIPPED OR CRACKED?

You must never pour your candles as soon as the wax has melted. You must let the wax cool to lessen the contraction when in the container or mould. Ideally, let the wax cool to around 50-55°c and pour into slightly warmed containers. For better results, it's worth investing in a cooks thermometer which can be found here.
 
If your candle has dipped you will need to do a second pour or if you have used all the wax, you will need to melt down and start again. Some slight surface imperfections can be corrected with a hair dryer or heat gun held at a distance.
