Wick Series Guide
ECO
Cotton with paper threads. Clean burn, great for soy wax.
CD
Cotton with paper filament. Self-trimming, good scent throw. Works with soy and paraffin.
Wood
Sized by width (0.5"-0.75"). Creates crackling sound. Use booster/double-ply for soy wax.
LX
Flat braided cotton. Curls when burning, low soot. Better for paraffin.
Wick sizes are general recommendations for soy wax container candles. Always test burn your candles — factors like wax type, fragrance load, dye, and container shape all affect performance.
How to choose the right wick size
The most important factor in wick sizing is the container diameter — not the volume or height. A wick that is too small will tunnel (leave unmelted wax on the sides), while a wick that is too large will produce excess soot and may overheat the container. Start with the recommended sizes above and adjust based on test burns.
What is a test burn?
A test burn means lighting your candle and letting it burn for one hour per inch of diameter. For a 3-inch candle, burn for 3 hours. The melt pool should reach the edges of the container without excessive smoking. Wick up (use a larger wick) if the melt pool doesn't reach the edges. Wick down if there's excessive soot or mushrooming.
Cotton vs. wood wicks
Cotton wicks (ECO, CD, LX series) are the most versatile and widely used. They work well with most wax types and fragrances. Wood wicks create a distinctive crackling sound and a wider flame, but they can be trickier to work with — especially in soy wax, where a booster or double-ply thickness is often needed for consistent burning.
When to use multiple wicks
Containers wider than 4-5 inches often perform better with two or three smaller wicks instead of one large one. Multiple wicks provide more even heat distribution, better melt pool coverage, and reduced tunneling. Space wicks evenly and use smaller sizes than you would for a single wick.
