A candle pour temperature guide tells you the exact wax temperature for each stage of candle making — when to add fragrance, when to pour, and how to avoid common defects like sinkholes, frosting, and rough tops.
Wax Temperature Reference
Cooling Timer
Set a countdown while your wax cools to the pour temperature.
Container Type Considerations
Can handle higher pour temps. Preheat jar in warm oven (150°F/65°C) to prevent cracking from thermal shock with hot pours.
Excellent heat conductors — cool faster, so pour at higher end of range. No preheating needed. Good for travel candles.
Thick walls hold heat — pour at lower end. Allow 48+ hours to fully cure. Avoid very high temp waxes in ceramic.
How to Use the Candle Pour Temperature Guide
Getting candle temperatures right is the difference between professional-looking candles and ones with sinkholes, frosting, or fragrance blowout. This candle pour temperature guide gives you exact target temperatures for every wax type, plus a timer to count down while your wax cools.
Step 1: Select Your Wax Type
Click any wax card to see the full temperature breakdown: melt point, fragrance add temperature, pour temperature range, and maximum fragrance load. Each wax has different chemistry that requires different handling — soy wax needs a lower pour temp than paraffin to avoid cracking issues.
Step 2: Add Fragrance at the Right Temperature
Always add fragrance oil before pouring — at around 185°F (85°C) for most waxes. This temperature is hot enough to fully bind the fragrance molecules into the wax matrix. Adding fragrance too late (at pour temperature) reduces scent throw. Never add fragrance above its flash point — check the SDS sheet for each fragrance oil.
Step 3: Use the Cooling Timer
After adding fragrance and stirring for 2 minutes, set the timer for 10-15 minutes to allow the wax to cool toward pour temperature. Stir occasionally. The wax should be at pour temperature when it just begins to look slightly opaque (for soy) or remains fully clear (for paraffin). Use a thermometer — don't guess.
Troubleshooting Common Issues
Sinkhole in the center: pour was too hot. Fix with a heat gun or second pour. Frosting on soy candles: natural and harmless — pour cooler and keep candles at room temperature while curing. Wet spots on glass: adhesion failure from temperature differential — try pouring warmer or preheating jars. Rough tops on soy: poured too cool or cooled too fast — raise pour temp by 5°F.
FAQ
What temperature do you pour soy wax?
Pour soy wax at 170-180°F (77-82°C). Add fragrance oil at 185°F (85°C) while still melted, stir thoroughly, then let it cool to pour temperature. Pouring too hot causes sinkholes; too cool causes rough tops.
What temperature do you add fragrance oil to candle wax?
Add fragrance oil at 185°F (85°C) for most waxes. This is hot enough to fully bind the fragrance but below the flash point of most fragrance oils. Always check your specific fragrance oil's flash point — never add fragrance above its flash point.
What is the maximum fragrance load for soy wax?
Soy wax typically holds 6-10% fragrance load by weight. Natural soy wax has a lower threshold than paraffin. Exceeding the max load causes fragrance oil to pool on top or sweat out of the candle.
Why does my candle have a rough or bumpy top?
Rough tops usually mean the wax was poured too cool, or the candle cooled too quickly in a cold room. Try pouring at the higher end of the recommended range, and keep finished candles in a warm (70°F+) room while cooling.
