How to Make Soy Candles at Home: A Beginner's Guide

Making your own soy candles is one of the most rewarding — and most affordable — crafts you can start this weekend. Whether you're testing recipes for a future Etsy shop or just want a candle that actually smells like your favourite fragrance oil, soy wax is the friendliest material to learn on. This guide walks through the full process, using the same soy wax, wicks and fragrance oils we stock for candle-making supplies across Montréal and Laval.

What you'll need

  • Soy candle wax — we recommend a fully-hydrogenated soy wax with a 49°C melt point for beginners.
  • Cotton or wood wicks, pre-tabbed, sized to your jar diameter.
  • Fragrance oil rated for candles (not all fragrance oils are — check for a candle-safe IFRA certificate).
  • Heat-safe jars or tins, cleaned and completely dry.
  • A double boiler or wax melting pitcher, a thermometer, and a stir stick.
  • Optional: a wick centering tool and a heat gun for a smoother top finish.

New to candle making entirely? Our Candle-Making Starter Kit bundles all of the above so you're not making six separate trips to gather supplies.

Step 1 — Melt the wax

Weigh your wax flakes and melt them in a double boiler, stirring occasionally, until the wax reaches 82°C (180°F). Never melt wax directly over an open flame or in the microwave — a double boiler keeps the temperature controlled and prevents scorching.

Step 2 — Add fragrance oil

Let the wax cool to 70–75°C (158–167°F), then add your fragrance oil. Most soy waxes perform best between a 6% and 10% fragrance load — meaning 6 to 10 grams of oil per 100 grams of wax. Going higher doesn't always mean a stronger scent throw; it can cause the candle to "sweat," develop wet spots, or affect how cleanly it burns. Use our Wax & Fragrance Load Calculator to get exact gram amounts for your jar size before you start — it already builds in a small wastage buffer so you don't come up short mid-pour.

Maker's tip: stir for a full two minutes after adding fragrance oil. Under-mixing is the most common cause of uneven scent throw between candles from the same batch.

Step 3 — Pour at the right temperature

Cool the fragranced wax to about 54°C (130°F) before pouring — this is the sweet spot for a smooth top and good glass adhesion. In warm or humid rooms, pouring a few degrees cooler (49–52°C) can help reduce frosting, the harmless white crystalline film that sometimes forms on cooled soy wax.

Hold your wick upright and centred as you pour — a wick centering tool or two chopsticks laid across the jar rim works well for small batches. Fill to just below the shoulder of the jar, leaving room for a second "flood pour" later if a sinkhole forms around the wick as it cools.

Step 4 — Cure before burning

This is the step most beginners skip, and it makes the biggest difference. Let your candles sit, untouched, for 3 to 7 days at room temperature before the first burn. Curing allows the fragrance oil to fully bind with the wax, which is what produces a strong "cold throw" (scent when unlit) and "hot throw" (scent when burning).

Step 5 — Trim the wick

Before every burn, trim the wick to 6 mm (¼ inch). A long wick causes soot, mushrooming and an uneven melt pool — one of the most common complaints candle sellers hear from customers, and one of the easiest to prevent with a simple wick trimmer and a note in your product care card.

Common problems, quickly explained

  • Frosting — a natural, harmless white bloom on soy wax; pour slightly cooler to minimize it.
  • Tunnelling — the candle burns a narrow hole down the middle; usually caused by an undersized wick or too short a first burn.
  • Sinkholes — a dip forms around the wick as wax cools; a second thin "flood pour" on top fixes this cosmetically.
  • Weak scent throw — check your fragrance load percentage and cure time before assuming the oil is at fault.
