Choosing the right candle wick will go a long way to ensuring it is safe to use and will also have a good burn rate. Some of the most popular types of wick include: CDN wicks: CDN wicks are zinc-free and offer enhanced rigidity, which makes them suitable for a wider range of waxes, with soy, palm and paraffin typically offering a good match. HTP wicks: Ideal for soy wax candles, HTP wicks are strong and rigid, whilst also being self-trimming and producing a softer burn. CL wicks: Cotton and linen wicks are produced by interweaving a linen thread with unbleached cotton. Afterglow and smoking are minimised and they work particularly well with vegetable and heavily fragranced mineral waxes. TCR wicks: Long strands of ring-spun cotton and paper are used to make this flat-braided wick. They offer a strong burn profile and work well with vegetable-based waxes like soy. Wedo Eco wicks: Thin paper filaments are interlaced with pure cotton to make Wedo Eco wicks, which produce a stable, consistent burn. These are a good choice if you are using higher concentrations of dyes and fragrances. Wooden wicks: This is a more modern wick type that are growing in popularity. Once ignited it produces a crackling flame similar to that of a fireplace, with a slow, even burn and a low, wide flame.
