The choice of wick depends mainly on the diameter of the container, the type of wax and the amount of fragrance or colourants. We recommend starting with the size indicated in the product parameters and then making a trial pour in the selected jar or pot. During testing, observe the width of the melt pool, the flame height, smoking and the behaviour of the candle during longer burning. If necessary, adjust the wick size up or down until you achieve stable and safe burning in the specific container.

Yes, you can use the Stabilo cotton wick size 12 in various types of containers and with different waxes, but it is always necessary to carry out a burn test in the specific packaging. Different shapes and diameters of jars, different wax density, and the content of fragrances or colourants can change the flame behaviour. We recommend always designing a trial series of candles, checking the burning over several cycles and only then finalising the formulation and wick size for serial production.

The wick is designed to work also in formulations with added fragrances and essential oils, but the specific suitability always depends on the type of wax, the amount of fragrance and the container diameter. A higher proportion of perfumes can affect the viscosity and flammability of the blend, which is why testing in the specific pot or jar is essential. If you notice excessive smoking or an overly strong flame during trial burning, consider adjusting the wick size or the fragrance ratio.

To make it easier to choose a suitable bottle, jar or pot, you can use the extended filter available at the top of the page after clicking on the relevant packaging category. In the extended filter you can set parameters such as neck type, size, colour or packaging material. In this way you can quickly narrow down the offer to containers that suit your candle formulation or another product you are preparing.

When testing a new combination of wax, wick and container, we recommend pouring the candle into packaging intended for candles and letting it cure sufficiently after pouring. Then light the candle on a flat, non-flammable surface, away from draughts and out of the supervision of children. Observe the burning at regular intervals (for example every hour), check the width of the melt pool, flame height, the temperature of the container walls and any smoking. Repeat the test several times so that you can be sure that the candle behaves stably even during longer burning.
