Wick and jar matching for a clean burn
Jar diameter drives melt pool width. Wick charts from suppliers are a starting point, not a promise—soy blends differ, and Los Angeles indoor dryness changes how fast a pool forms compared with coastal humidity.
Materials
- Two test wicks one size apart (same series)
- Ruler or calipers for inside jar diameter
- Timer and a heat-safe surface
- Same wax and fragrance load you plan for real batches
Steps
- Measure the inner width at the shoulder, not only the base—some jars taper.
- Pour two small testers differing only by wick size; label the bottoms.
- Burn in two-hour windows; note mushrooming, soot at the rim, and whether the pool reaches the wall.
- If the pool lags before the wall at hour three, step up; if the flame dances high early, step down.
Studio note: I keep a spare jar of the same lot for re-wicking demos—reusing wax teaches trimming discipline faster than charts.
