Candle Making Guide
Candle Knowledge Hub
Practical candle making tips for beginners and small-batch makers. Learn how to choose wax, select the right wick, calculate fragrance oil, prevent common candle problems, and test candles with more confidence.
Start with testing, not guessing: Wax type, wick size, fragrance load, pour temperature, and burn testing affect almost every candle result.
Start Here
If you are new to candle making, do not start by buying random materials. Start with these five basics.
Wax type Determines texture, scent throw, hardness, adhesion, mold release, and burn style.
Wick size Controls flame height, melt pool, heat, soot, hot throw, and burn safety.
Fragrance load Affects scent strength, wax stability, sweating, smoking, and wick performance.
Pour temperature Helps reduce sinkholes, rough tops, frosting, cracking, and poor adhesion.
Container choice Jar diameter, depth, and glass thickness affect wick choice and heat buildup.
Test burning Confirms whether the candle is balanced, safe, and ready to repeat.
Choose Your Candle Type
Different candle types need different waxes, wick choices, and testing standards.
Container Candles Best for jars, tins, and vessels. Focus on wax adhesion, wick sizing, hot throw, and jar temperature. Shop Container Wax → Wax Melts Best for clamshells, molds, and warmers. Focus on hardness, mold release, scent throw, and melt point. Shop Melt Wax → Pillar & Molded Candles Best for freestanding candles, votives, and molded shapes. Focus on hardness, shrink, release, and burn stability. Shop Pillar Wax → Wax Additives Use additives to adjust hardness, opacity, scent retention, mottling, gloss, or structure. Shop Wax Additives →

Common Candle Problems
| Problem | Common Cause | First Fix to Test |
|---|---|---|
| Tunneling | Wick too small, first burn too short, wax too hard, or poor vessel match | Test a larger wick and burn long enough to evaluate the melt pool. |
| Smoking | Wick too large, wick not trimmed, too much fragrance oil, excess dye, or airflow | Trim the wick, reduce wick size, or lower fragrance/dye load. |
| Frosting | Common in natural soy wax; affected by temperature, cooling speed, fragrance, and wax formula | Adjust pour temperature, cooling conditions, and wax selection. |
| Rough or bumpy tops | Uneven cooling, pour temperature mismatch, sensitive wax formula, or room temperature swings | Adjust pour temperature and cooling environment. |
| Weak hot throw | Wrong wax, poor wick match, short cure time, fragrance mismatch, or incorrect fragrance load | Retest wick and cure time before simply adding more fragrance oil. |
| Jar too hot | Wick too large, too many wicks, narrow vessel, deep melt pool, or high fragrance load | Stop using that formula and test a smaller wick or different vessel. |
Simple Testing Workflow
This is the part beginners skip. That is why their results feel random. Do not change wax, wick, fragrance oil, dye, and container all at once.
1
Choose one wax and one container Do not test five waxes in five different jars at the same time.
2
Select 2–3 possible wick sizes Use a wick guide, then test one smaller, one suggested, and one larger.
3
Use a consistent fragrance load Start within the wax supplier’s recommended range.
4
Let the candle cure Give the wax and fragrance time to settle before judging hot throw.
5
Burn in 3–4 hour sessions Track flame height, melt pool, jar temperature, soot, mushrooming, and scent throw.
6
Change one variable only Change the wick, wax, fragrance, dye, or vessel one at a time so you know what caused the result.
Material Selection Cheat Sheet
| Project | Best Starting Material | What to Watch |
|---|---|---|
| Jar candles | Container soy wax, coconut-soy wax, paraffin-soy blend | Glass adhesion, sinkholes, hot throw, jar temperature, wick size |
| Tins | Container wax with good heat control | Tins heat fast; avoid over-wicking. |
| Wax melts | Melt wax / tart wax / firmer soy blend | Mold release, fragrance load, hardness, melting behavior |
| Pillar candles | Pillar wax or molded candle wax | Hardness, shrink, release, cracking, freestanding burn |
| Decorative candles | Depends on shape: pillar wax, paraffin, beeswax, sand wax, gel wax | Decoration safety, wick placement, heat movement, burn suitability |
| Additive testing | Stearic acid, Vybar, micro wax, UV inhibitor, specialty additives | Add slowly and test. Too much additive can create new problems. |
