Candle Making Mistakes to Avoid — Common Beginner Errors

Every candle maker has ruined a batch at some point. Tunnelling, sinkholes, weak scent, sooty flames — these problems seem mysterious at first, but almost always come down to a handful of fixable mistakes.

If your candles aren't turning out right, this guide will help you identify exactly what went wrong and how to fix it.

Mistake 1 — Using the Wrong Wick Size

The wick is the most common cause of candle problems. Too small and you get tunnelling — only a narrow hole melts down the centre. Too large and you get a sooty, overheating flame.

Fix: Match your wick to your container diameter using a size chart. If you're looking to buy candle wicks online, KSMA offers pre-tabbed cotton wicks in sizes 1–6 inches — always test burn before finalising your batch.

Mistake 2 — Skipping the Test Burn

Making a candle and using it without a proper test burn leads to surprises — tunnelling, drowning wicks, poor scent throw — only after it's too late.

Fix: Always do at least 3 test burns with any new wick, wax, or fragrance combination. Burn 2–3 hours each time and check the melt pool, flame height, and scent throw before a full batch.

Mistake 3 — Adding Fragrance at the Wrong Temperature

Too hot, and the scent evaporates before the candle sets. Too cool and it won't blend, causing separation or poor throw.

Fix: Add fragrance at the correct temperature:

• Soy wax: 65–70 °C
• Paraffin wax: 70–75°C
• Coconut wax: 55–60°C

Use a thermometer — never guess. Shop KSMA's candle-grade fragrances for proper flash points.

Mistake 4 — Not Curing the Candle

Lighting a candle right after it sets is a top beginner mistake. The fragrance hasn't fully bonded with the wax yet — scent throw will be weak or barely noticeable.

Fix: Cure soy wax candles for a minimum of 48–72 hours before burning. Many experienced makers cure up to 2 weeks for maximum scent throw.

Mistake 5 — Sinkholes Around the Wick

A dip or hole forming around the wick happens because wax contracts as it cools, and the centre solidifies last.

Fix: Pour at 55–60°C and cool slowly at room temperature away from fans or AC. If a sinkhole forms, do a second pour with reheated wax to top it up. If you're looking to buy soya wax online India or coconut wax in India, note that both are more prone to sinkholes than paraffin — second pours are a standard part of the process.

Mistake 6 — Wet Spots on Jar Candles

Wet spots are patches where wax has pulled away from the glass, creating a patchy look. Cosmetic issue — doesn't affect burn quality.

Fix: Warm glass jars slightly before pouring and avoid cold or draughty spots while setting. This issue is more common with soy wax than with paraffin wax — a soy-paraffin blend gives a cleaner finish if wet spots are a concern.

Mistake 7 — Adding Too Much Fragrance

Exceeding the recommended fragrance load causes oil seepage, clogged wicks, and a weak flickering flame.

Fix: Stick to 6–10% fragrance load by weight. For 100g of soy wax, add a maximum of 10g of fragrance. Always measure by weight, not volume. Note that beeswax holds only up to 6% fragrance — going beyond this is one of the most common beeswax mistakes.

Mistake 8 — Not Trimming the Wick

An untrimmed wick causes a large, flickering flame, excess soot, mushrooming on the tip, and black deposits on the jar.

Fix: Trim the wick to 5–6mm before every single burn — including the very first. Use scissors or a wick trimmer for a clean cut.

Mistake 9 — Using Non-Candle Colourants

Crayons, fabric dye, food colouring — they don't dissolve in wax, clog the wick, and cause uneven burning.

Fix: Only use candle-specific colourants. If you want to buy candle pigments in India, KSMA's range is oil-soluble and wick-safe — available in 12+ colours, including red, gold, pink, and black.

Mistake 10 — Rushing the Pour

Pouring too quickly causes air bubbles, uneven surfaces, and a shifted wick.

Fix: Pour slowly from a jug with a narrow spout. Keep the wick centred with a holder or pencil while pouring.
