DIY candle making seems simple—melt, pour, light. But anyone who’s tried it knows there’s a fine line between cozy and chaotic. Sinkholes, tunneling, soot, and mystery scents that disappear mid-burn? All too common.
The good news: you can avoid the usual frustrations. And if you're using a refillable candle system like ours, you're already one step ahead—no mess, no guesswork, just clean-burning simplicity.
Here’s what to watch out for—and how to make DIY candles that actually burn beautifully.
Why DIY Candle Making Gets Messy
Let’s be real—most candle-making fails start with good intentions and end with sticky counters and uneven burns. That’s because so many things need to go just right: the wick size, the wax temp, the fragrance load, and even the room temperature.
DIY kits and tutorials rarely mention the setup it takes to get clean results:
- Prepping jars
- Measuring wax weights and fragrance ratios
- Curing for days
- Testing for scent throw
- Hoping your jar doesn’t crack or your wick doesn’t lean mid-pour
And that’s before cleanup.
Refillable candles take most of these variables out of your hands—because why should sustainable living require a chemistry degree?
7 Common Candle Making Mistakes and How They Happen
- Pouring into a cold jar: That sudden temp change causes cracks, sinkholes, and weird texture lines (aka “jump lines”).
Fix: Warm your jar slightly before pouring—or skip the pour with a pre-formed wax refill.
- Wrong wick size or type: Not all wicks are created equal. Too small? You'll get tunneling. Too big? Hello, soot and mushrooming.
Fix: Choose the right wick for your wax and jar size—or let a pre-matched cotton wick do the work.
- Skipping the cure or first burn rules: Soy wax needs time. Lighting too soon or blowing out too early leads to memory rings (the candle only burns in that first circle forever).
Fix: Let your candle cure for 48+ hours, then burn edge-to-edge the first time.
- Overloading fragrance or using the wrong oils: More isn’t always better. Too much fragrance oil can clog the wick or mess with burn quality. And perfume? A big no.
Fix: Stick to clean, candle-safe fragrance oils—ours are non-toxic and Prop 65–compliant.
- Pouring too hot (or too cold): If the wax is too hot, you risk sinkholes or poor adhesion. Too cold? Lumpy tops and bad texture.
Fix: Pour within the recommended temp range for your wax (usually around 130–150°F). Or, opt for our specialized soy wax refill that’s already dialed in.
- Moving the jar or wick post-pour: Tempting as it is to adjust a leaning wick, it can ruin the setting process.
Fix: Secure the wick before you pour and let the candle cool in a stable spot.
- Burning too long or too short: Overburning causes soot and wick “mushrooming.” Too short and you get tunneling.
Fix: Burn for about 1 hour per inch of candle diameter. Most of our refills are sized perfectly for even, clean melts.
How Refillable Candle Systems Help You Skip the Mess
Let’s be honest—DIY candle making can be a mess. But it doesn’t have to be.
Here’s how ReCandle Co. simplifies the whole thing:
Pre-measured wax refills mean you don’t have to weigh or mix anything—no guessing fragrance ratios or worrying about overflow.
Our cotton wicks are already trimmed and centered, matched to the wax and ceramic vessel for optimal performance.
The wax is designed to contract as it cools—so it naturally pops out when you’re ready for a new one. No scraping, heating, or cleaning involved.
Everything is made to fit together, beautifully. Refill. Relight. Repeat.
With zero waste candle refills, you're skipping the trial and error (and the trash).
Quick “Pro Tips” for Clean DIY Candle Making
If you're experimenting beyond the refill system, or just want to know what works best, keep these in your back pocket:
- Pre-warm your jar before pouring to avoid sinkholes or cracking.
- Trim your wick to ¼ inch before every burn for the cleanest flame.
- Let your first burn go edge-to-edge—usually about an hour per inch wide—to avoid tunneling.
- Cool in a draft-free zone and don’t move the container until fully set.
- Tin foil fixes tunneling but only as a last resort. Better to get the first burn right.

FAQ
Why did my candle tunnel even though I trimmed the wick?
The wick length matters, but so does the first burn. If you don’t let the wax melt all the way across, you create a “memory ring” and tunneling happens next time.
How long should I cure a ReCandle wax refill?
All our wax refills are pre-cured for at least 48 hours—so they’re ready to use when they arrive. No waiting.
Are refillable candles harder to make than traditional DIY?
Not at all. In fact, they’re easier. No melting, mixing, or wick-guessing—just drop in a refill and light it up.
