Candle wax melts between 76°F and 147°F depending on the wax, and is poured cooler than it is melted: soy pours at 130-150°F, paraffin at 160-180°F, beeswax at 155-165°F and coconut at 145-160°F. The table below is the short version; the rest of this guide is every other temperature in the process.
Melting Point and Pour Temperature by Wax Type
| Wax Type | Melting Point | Pour Temperature | Heat To | Never Exceed |
|---|---|---|---|---|
| Soy | 120-125°F (49-52°C) | 130-150°F (54-66°C) | 170-180°F | 200°F |
| Paraffin | 125-140°F (52-60°C) | 160-180°F (71-82°C) | 180-190°F | 200°F |
| Beeswax | 144-147°F (62-64°C) | 155-165°F (68-74°C) | 160-175°F | 185°F |
| Coconut | 76-100°F (24-38°C) | 145-160°F (63-71°C) | 150-160°F | 180°F |
Three questions this table answers
What is the melting point of candle wax? Between 76°F and 147°F, depending on the wax. Coconut is the softest at 76-100°F, soy melts at 120-125°F, paraffin at 125-140°F and beeswax is the hardest at 144-147°F. Melting point is not the same as the temperature you heat to: every wax is taken 30-60°F above its melting point so the fragrance binds.
What temperature should I pour candle wax? Soy at 130-150°F, paraffin at 160-180°F, beeswax at 155-165°F and coconut at 145-160°F. Pour toward the top of the range to reduce frosting and toward the bottom of it for better glass adhesion.
What is the difference between melting point and pour temperature? The melting point is where the wax turns liquid; the pour temperature is where you actually fill the container, always well above the melting point but cooled down from the heating temperature so the wax sets evenly instead of pulling away from the glass.
Temperature control is the most critical technical skill in candle making. Getting temperatures wrong by even 10-15°F can ruin an entire batch. The rest of this guide covers every other temperature in the process, a troubleshooting matrix linking common defects to their temperature causes, and step-by-step workflows to prevent them. Wick size shifts with wax type too - the candle wick size chart carries the multipliers.
🌡️ The Golden Rule of Temperature Control
NEVER guess temperatures. A $15 digital thermometer will save you hundreds of dollars in wasted materials and failed batches.
- • 5° too hot when adding fragrance = 30% scent loss
- • 10° too cool when pouring = sinkholes, wet spots, poor adhesion
- • 20° temperature shock = cracked glass containers

📝 Notes on Temperature Ranges
- • ±2° means stay within 2°F of target for best results
- • Ranges allow adjustment based on specific wax brand and environmental conditions
- • Higher pour temps reduce frosting but may cause poor adhesion
- • Lower pour temps improve adhesion but may increase frosting/sinkholes
- • NEVER heat wax above max safe temp - causes discoloration and degradation
2 Temperature Troubleshooting Matrix
Use this matrix to diagnose and fix temperature-related problems. Most candle issues trace back to incorrect temperatures!
🔴 Problem: Sinkholes (Crater in Center)
Temperature Causes:
- • Poured too cool (< 130°F for soy)
- • Cooling too fast (cold drafts)
- • Ambient temp too low (< 65°F)
Temperature Solutions:
- ✓ Pour at 140-150°F (soy) or 165-175°F (paraffin)
- ✓ Preheat containers to 90-100°F
- ✓ Let cool in 70-75°F room, no drafts
- ✓ Use two-pour method (second pour at 160°F)
🔴 Problem: Frosting (White Crystals on Soy Wax)
Temperature Causes:
- • Poured too cool (< 135°F)
- • Temperature fluctuations during cooling
- • Cooling too quickly
Temperature Solutions:
- ✓ Pour at 145-150°F (higher end for soy)
- ✓ Preheat containers to 100-110°F
- ✓ Maintain consistent room temp (72-75°F)
- ✓ Avoid drafts and AC vents
Note: Some frosting is natural for 100% soy wax. Can't be 100% eliminated.
🔴 Problem: Wet Spots (Wax Pulling from Container)
Temperature Causes:
- • Poured too cool (poor adhesion)
- • Container too cold
- • Temperature difference wax vs. container
Temperature Solutions:
- ✓ Lower pour temp (130-135°F for soy)
- ✓ Preheat containers to 100-120°F
- ✓ Pour in warm room (75-78°F)
- ✓ Add vybar at 180°F (1% by weight)
🔴 Problem: Weak Scent Throw
Temperature Causes:
- • Fragrance added too hot (> 190°F = evaporation)
- • Fragrance added too cool (< 165°F = poor binding)
- • Inadequate stirring time after adding fragrance
Temperature Solutions:
- ✓ Add fragrance at EXACTLY 175-185°F (±2°)
- ✓ Stir for full 2 minutes after adding
- ✓ Let cool naturally to pour temp
- ✓ Never reheat after adding fragrance
🔴 Problem: Rough, Pitted Surface
Temperature Causes:
- • Poured too hot (air bubbles trapped)
- • Stirred too vigorously (introduced air)
- • Cooling too fast
Temperature Solutions:
- ✓ Pour at lower temp (135-140°F for soy)
- ✓ Pour slowly and steadily
- ✓ Use heat gun on surface before wax sets
- ✓ Control cooling rate (warm room)
🔴 Problem: Cracked or Shattered Glass Container
Temperature Causes:
- • THERMAL SHOCK: Temp difference > 100°F
- • Hot wax into cold container
- • Container on cold surface during pour
Temperature Solutions:
- ✓ ALWAYS preheat containers (90-100°F minimum)
- ✓ Use heat-safe glass only
- ✓ Pour on insulated surface
- ✓ Test containers before bulk buying
🔴 Problem: Discolored or Yellowed Wax
Temperature Causes:
- • Wax overheated (> 200°F)
- • Heated for too long at high temp
- • Fragrance oil added too hot (scorched)
Temperature Solutions:
- ✓ Never exceed max safe temp (200°F)
- ✓ Use thermometer - don't guess!
- ✓ Melt wax just until liquid, not longer
- ✓ Use lower heat settings

- • Analog thermometers: Slow response, less accurate
- • Guessing temperatures: The #1 cause of failed batches!
4 Step-by-Step Temperature Workflow
Follow this exact workflow to maintain perfect temperature control throughout the entire process:
Perfect Temperature Workflow (Soy Wax Example)
Setup & Preheat (Before Melting)
- • Set up double boiler on medium-low heat
- • Place containers in 100°F oven to preheat (30 min)
- • Prepare thermometer and have it ready
- • Pre-measure fragrance oil, keep at room temp
Melt Wax (Target: 170-180°F)
- • Add wax flakes to double boiler
- • Stir occasionally to promote even melting
- • Monitor temperature continuously
- • When wax reaches 170-180°F, remove from heat
- • Do NOT exceed 200°F
Add Dye (Optional) (175-180°F)
- • Wait for wax to be 175-180°F
- • Add dye chips or liquid dye
- • Stir gently for 1-2 minutes until dissolved
⭐ Add Fragrance (CRITICAL: 175-185°F ±2°)
- • Wait for EXACT temperature: 175-185°F
- • If too hot, wait. If too cool, gently reheat
- • Add pre-measured fragrance oil
- • Stir gently but thoroughly for 2 full minutes
- • This is THE most important temperature step!
Cool to Pour Temperature (130-150°F)
- • Let wax cool naturally (do NOT refrigerate)
- • Monitor temperature every 2-3 minutes
- • For less frosting: Pour at 145-150°F
- • For better adhesion: Pour at 130-135°F
- • Stir gently every few minutes while cooling
Pour Candles
- • Remove preheated containers from oven (use gloves!)
- • Check pour temperature one final time
- • Pour slowly down side of container
- • Center wick immediately
- • Do NOT move containers for 24 hours
Cool & Cure (65-75°F Room Temp)
- • Let candles cool in room temp environment (68-75°F)
- • Avoid drafts, AC vents, or direct sunlight
- • Wait 24 hours before moving
- • Cure for 1-2 weeks before burning/selling
5 Environmental Temperature Factors
Ambient temperature affects your candles more than you might think. Control your environment for consistent results.
❄️ Cold Weather / Winter (< 65°F)
Impact: Faster cooling, increased frosting, sinkholes
Adjustments:
- • Pour at higher temps (+5-10°F)
- • Preheat containers longer (45 min at 110°F)
- • Work in heated room (72-75°F minimum)
- • Cover candles while cooling (cardboard box)
- • Expect longer cure times
🔥 Hot Weather / Summer (> 80°F)
Impact: Slower cooling, potential melting, wet spots
Adjustments:
- • Pour at lower temps (-5-10°F)
- • Use AC to cool room to 70-72°F
- • Be extra careful with soy (soft wax)
- • Store finished candles in cool place
- • Shorter cure times may be acceptable
💨 Humidity Impact
High Humidity (> 60%):
- • Can cause frosting on soy wax
- • Longer cure times needed
- • Use dehumidifier if possible
Low Humidity (< 30%):
- • Faster evaporation (cover candles)
- • Static electricity issues
- • Generally easier for candle making
📍 Altitude Considerations
High Altitude (> 5,000 ft):
- • Water boils at lower temp (affects double boiler)
- • May need to adjust pour temps slightly
- • Faster evaporation of fragrance
- • Test and document your specific results
