What Temperature Should I Pour Candle Wax?
Share
Pour temperature is one of the most discussed- and misunderstood- variables in candle making.
There is no single “correct” temperature.
The right pour temperature depends on wax type, fragrance load, vessel conditions, and desired finish.
Why Pour Temperature Matters
Pour temperature affects:
- glass adhesion
- surface finish
- fragrance binding
- cooling behavior
Small changes in temperature can produce very different results.
General Temperature Ranges
Most waxes fall within a general pour range:
- Soy wax: typically 120–160°F
- Paraffin: typically 150–180°F
- Blends: vary depending on formulation
These are starting points- not rules.
Pouring Too Hot
Higher pour temperatures can:
- improve adhesion in some cases
- reduce surface imperfections
But may also:
- increase shrinkage
- create more visible pull-away
- affect fragrance performance
Pouring Too Cool
Lower pour temperatures can:
- reduce shrinkage
- improve surface appearance
But may also:
- lead to poor adhesion
- create uneven tops
- affect fragrance binding
The Role of Fragrance Oil
Fragrance oil changes how wax behaves.
Adding fragrance:
- lowers the overall temperature
- affects how the wax cools
- can shift the ideal pour range
This is why testing is required after adding fragrance.
Glass Temperature Matters
The vessel itself plays a role.
Pouring into cold glass can:
- accelerate cooling
- increase contraction
- worsen adhesion issues
Preheating vessels can help stabilize results.
The Right Approach
Instead of searching for one ideal temperature:
- test within a range
- observe results
- adjust based on performance
Consistency is more important than hitting an exact number.
Final Thought
Pour temperature is not a fixed number.
It is a variable that must be controlled, tested, and refined.
Better results come from consistency- not guesswork.
