Candle Wicks

About Candle Wicks

candle wickWicks are the most important item for a well performing candle and so it's important that you have a wide selection of wicks to choose from. At Eroma, you will find wicks in several sizes of both length and burn rate and it is here that we will describe all the wick variables. Note: It's most important that you select a variety of wicks for your intended application as testing will be required to ensure that you find the most suitable wick for the product. 

How do I select the correct length of wick?

Our wicks are available in the 27mm, 33mm, 150mm, 300mm or on spools:

  • wick length27mm - These wicks are for use in Tea Light candles only.
  • 33mm - These wicks are for use in tealight candles only, but due to the longer length they are suitable for the larger Tealight Cups.
  • 150mm - These wicks are for use in tins and glassware and have what is called a tab on the bottom. This has two main purposes: first, to anchor and secure the wick to the bottom of the container; and, secondly, to stop the flame near the bottom so that the heat does not transfer to the base of the container.
  • 300mm - These are the longer wicks suitable mostly for Pillar type candles. They have no tabs on the bottom, but if need be the tabs can be manually applied. Note: For customers wanting larger tabbed wicks beyond 150mm, Eroma can custom make special wick sizes and lengths for you.

What wick should I select and what do the numbers mean?

candle wicksOne of the most common questions in candle making is "What wick should I use?" This can be a complex process, but here at Eroma we aim to take the confusion away. The most important advice we can give is to visit the products section and make sure that you click on the images or 'More Information' as this is where you will find the wick suggestions for each product. Wicks are numbered from the lowest to the highest. For example, the CDN (stabilo) 3 is the smallest wick in the CDN (stabilo) range and this means that it has a smaller flame and is suitable only for the smaller type products such as tealights. On the contrary, the CDN 22 is for large tins and glassware and has a larger flame. The same applies to the HTP range of wicks with the HTP 31 being the smallest and the HTP XL-100 the largest.

Below is a table you can use for reference. Matching the diameter of your desired container to the burn diameter of a wick shown in the table is a good indication of which wick you should begin testing with.

Note: These are the results of wicks freely burning in Golden Wax 464, meaning they were not burnt in containers and do not account for the accumulated heat generated by the wall of of the container. Results will vary depending on which wax is used.

The general rules for wick type selection are below -

Palm Waxes - Use CDN (stabilo) wicks.
Soy Waxes - Use HTP wicks.
Paraffin Wax - Use CDN (stabilo) wicks.

How am I going to know if I need a smaller or larger wick?

various wick sizesIn order to find the perfect wick you have to examine the entire burning process. For example, if you would like a candle to be burnt for one-hour intervals, this will need a different wick to one that is burnt for three-hour intervals. The reason is that the candle wax burns out and then down so for short durations the wax may not reach a full molten pool and residual solid wax will remain on the sides of the container or pillar. If you intend to burn the candle for shorter or longer durations, then you may have to vary your wick sizes up or down from our info, so the general rule is that for longer burn durations, go down in wick size and for shorter burns, go up in wick size. We estimate that an average burn is two to three hours.
Another variable to keep in mind when selecting a wick is wax with colour and/or fragrance, as this can affect the burning process. The rule is that the moment you change any variable such as fragrance, colour, container type/size or mould type/size, then you will need to test again as the most suitable wick may differ. The perfect wick is all about testing, so we highly recommend that you purchase a range of small wick packs and only then buy the larger packs, once you find the ideal wick for each application.

What are wick wax coating, raw spooled wick and wick tabs?

wick spool

Why do we need wick wax coatings? Most people use glass containers with their diffuser oils, the reason being that some other substances such as plastics or metal may react with the fragrance oils. Plus, as you can see from the photos on the left, it's easy to see why people prefer glassware. It looks quite elegant when filled with diffuser oil and diffuser reeds.

Raw wicks and spools - As outlined above, you can only use the raw wick spools in pillar candles. If pouring your pillars and using a wick pin, you may find it difficult to thread the wick through the pillar hole after the candle has set (due to the lack of rigidity in the raw wick), so for this reason we do offer a wide range of pre-waxed wicks without tabs and these will allow you to easily feed the wick through the hole. Some candle makers do place and secure the wick into a mould before pouring and this is where raw wick can be effective.

Wick tabs - These are an essential item for container candles so that you can secure the wick to the bottom of the container. They also act as a safety cut-out so that the candle does not build up too much heat at the end of the burn. If you intend to make pillar candles, then you can also leave the safety wick tab on. However, if you do intend to make pillar candles without wick tabs, then use caution and always place the pillars on a heat-resistant surface.

Do you have a need for custom wicks?

custom wickNo problem, Eroma operates the most advanced wick production technology in the world, so no matter what wick type, size or tab, we can custom make these to suit your needs. Having the most suitable wick will reduce your labour costs and our quick turnaround times will mean you can manage your cash flow and only order when you need the product. Note: Minimum quantities are required for custom production runs.
