Candle Making FAQ’s

I am new to candle making, how do I get started?

The best way to get started with candle making, is by trying our candle making kits. After all, practice is the best way to learn!

We have a step by step candle making guide here which helps you with your first steps to becoming a candle making pro.

If you do have any problems you can call us on (+44) 1709 588579 or drop us an email at info@soapsupplier.co.uk.


How much wax will fill my containers?

To work out the amount of wax you need to fill your container, first fill your container with water.

Once the container is full, pour the water into a measuring jug.

You then need to minus the amount in the jug by 20%, this will give you the total amount of wax the container will hold in grams.

For example, if a container holds 100 ml of water, it will roughly hold 80 grams of wax.


CLP Labelling

Under the General Product Safety Regulations 2005, it is required that all producers and distributors of any potentially dangerous product must be fully labelled with information and warnings relating to that product.  Our candle safety label contains all the information a consumer may need to safely use your candles. So for this area, we have you covered!

Your candles or melts must also be CLP compliant. The CLP Regulation (for “Classification, Labelling and Packaging”) is a European Union regulation from 2008, which aligns the European Union system of classification, labelling and packaging of chemical substances and mixtures to the Globally Harmonised System (GHS).

This article gives a great summary of CLP and it’s requirements. http://www.cirs-reach.com/CLP/Labelling_Packaging.html

Fragrances all contain a number of different chemicals, some potentially more harmful than others. This means each candle with a different fragrance will require it’s own CLP label, with all the hazards and pictograms which come with that fragrance. But remember – you are not using 100% fragrance, you are using 90% wax and 10% fragrance, so we supply a data sheet which contains all the hazards for the fragrance at 10% (for candles and melts) and 25% (for reed diffusers.)

To make CLP even easier, we have already created a CLP template for each fragrance for you, the CLP label can be downloaded under the data sheet tab for each fragrance. SImply download, edit your company details, print using a label printer, you can now legally sell your candles.

For 25% reed diffuser labels, simply download the 25% fragrance data sheet. Once downloaded, open the data sheet and scroll to section 2.2 ‘Label Elements.’ Everything in this area needs to be put directly onto your candle label. Try editing the candle CLP label and adding the extra hazards which arise at 25% to easily create your own diffuser labels.

Why when I use different fragrances I don’t get a full melt pool?

Fragrances all have different specific gravity and flash points which effect the burn of your candle.

Heavy fragrances such as vanilla will require larger wicks, compared to light fragrances like orange.

Every candle with a different fragrance needs to be tested for the correct wick size.


Why do my candles develop sink holes?

Sink holes are an unavoidable part of candle making, it is caused by the wax shrinking.

To minimise sink holes pour at a lower temperature and preheat your containers.

The best way for a flat surface is by doing a second pour to smooth out the sink hole. Ensure the wax is poured at the same temperature.


Why is my candle sweating? Why is there oil droplets on the surface?

This is caused by overloading the wax with fragrance, causing the fragrance to leach out.

Try using less fragrance to avoid this.


My candle appears to have snow flake like marks?

This is known as ‘mottling.’ This is caused by too much oil to being added to the candle, or the candle being cooled too quickly.

Try reducing fragrance load and preheating the containers.


My candle has air bubbles?

Air bubbles are caused from the wax setting too quickly, or the wax being poured too fast.

Try preheating the containers to slow the cooling temperature.

Use a steel pouring jug and pour carefully.


Why does my candle have white lines or frosting?

Frosting is caused by the wax being poured at the incorrect temperature, usually too cool.

Try increasing the pour temperature.

For best results, use trial and error – pour a number of candles in 5 degree increments to see which gives the best results to minimise frosting.


Why does my candle not have a strong scent throw?

Poor scent throw can be caused by a number of factors.

Ensure you are using the maximum fragrance load in the wax (usually 10%.) Fragrance load can be increased by adding Vybar to the wax.

Ensure you are not burning off the fragrance. Many fragrances have a flash point of 70 C, if you add fragrance to the wax at this temperature, you risk burning off a lot of the scent.


My candle appears to have wet spots?

Wet spots are caused by the wax not adhering fully to the glass.

To avoid this try pouring at a lower temperature. Other solutions are preheating the containers or using a softer wax.

Heat guns can also be used on the outside of the container to minimise wet spots.


I can’t get my wax out of the mould?

Try spraying your moulds with silicone spray to aid in mould release.

Try adding Vybar or Palm Stearin to increase hardness of the wax to help this.


Why has my candle formed cracks?

Cracks are generally caused by the wax being cooled too quickly.

Try preheating your containers before pouring, or allow to set in a warmer room.


Why does my second pour not blend into the first?

This caused by the second layer not being poured at the same temperature as your first pour.

Wax sets up differently depending on temperature, ensure your second pour is the same temperature as your first pour.


Why is my candle producing smoke?

There are a number of causes for a candle to produce smoke.

The most common reason is the wick is too large, or the wick hasn’t been trimmed short enough.

Other causes are fragrance overload and air pockets in the wax.

Make sure the candle isn’t over wicked, and ensure the wick is trimmed to less than 2 cm.

Try reducing fragrance load and pouring the wax more slowly to reduce air pockets.


Why is my wick not keeping upright?

A good trick is to hold the wick upright when pouring wax into your containers are clothes pegs rested on the top of the glass with the wick running through the middle.

Another tip is using 2 pencils or BBQ skewers to hold the wick in place.


Why is my candle not staying alight?

The major cause for candles extinguishing themselves is due to the wick being too small. Try a larger wick size.

Another explanation is the wick is too large, and the flame is being extinguished in the melt pool. Try using a smaller wick size to decrease the melt pool depth.


Why is my candle leaving wax around the edge? Why is my melt pool small?

The main cause of wax not melting to the edge is from using a too small wick. This is known as tunnelling.

Try using a larger wick to increase the melt pool to reach the edge of the container.


What is causing my flame to flicker?

The most common reason for the flame flickering is because the candle is over-wicked. Try a size smaller wick to reduce this.
