Wedo ECO (line)

Flat cotton-paper braided wicks that burn cleanly in soy and other natural waxes, with a sizing ladder that makes test burns simple.

Not for: Paraffin or heavily fragranced and dyed candles, where a hotter series often performs better.

CandleScience ECO 8

Cotton-and-paper construction and pretabbed convenience make this a practical starting point for testing soy container candles.

Not for: Untested wax-and-container combinations; proper wick sizing requires burn testing.

Size by diameter and wax. Choose wick size by vessel diameter and wax type, then test burn one size up and down. No chart replaces a test burn, because fragrance, dye and vessel shape all change performance.
Melt pool test. A good wick reaches a full melt pool to the edge in a burn of a few hours without a tall, smoking flame. Undersized wicks tunnel; oversized wicks soot, mushroom and overheat the glass.
Wick series matched to wax. Cooler, flat-braided series suit soy; hotter or cored series suit dense paraffin or thick, viscous blends. Each series is designed for a specific wax viscosity.
Pre-tabbed and primed. Buy pre-waxed wicks with sustainer tabs in a length suited to the container height. Priming helps the first light, and tabs safely extinguish the flame at the bottom.

Should I use two wicks?

For wide vessels, often yes; two or three smaller wicks melt the surface evenly where one large wick would run hot.
