Your candle components’s intrinsic residences—wax kind, fragrance load, and wick configuration—are paramount in dictating the critical glass jar characteristics for top of the line performance and protection. Mismatches can compromise burn pleasant, reduce heady scent throw, or, seriously, result in jar failure, impacting logo popularity and purchaser safety.
1.1. Wax Type and Fragrance Load Dynamics
Wax preference profoundly impacts burning traits and perfume retention. Different waxes impact fragrance-protecting ability and melting points, affecting heady scent release.
Paraffin Wax:
Can maintain excessive fragrance loads (as much as 12% with components) for sturdy hot throw.
Soy Wax:
- Eco-pleasant, lower melting point; may also yield weaker scent throw if not well formulated/depraved. Coconut Wax:
- Lower melting point than soy, easy burn, sturdy fragrance throw because of creamy texture. Rapeseed Wax:
- Vegetable-primarily based, clean burn, potent fragrance throw, lower melting point than soy, clean to work with. Strictly adhere to wax producer’s maximum fragrance load pointers. Exceeding limits reasons bad burn, sweating, oil seepage, and fireplace risks 610. Calculate perfume load by weight for precision.
- Fragrance compatibility with wax is essential; some combos motive clouding, discoloration, or separation.Total perfume load need to no longer exceed wax limits.Viscous fragrances may additionally need better pouring temperatures (>60℃) for dispersion. Potent scents like Vanilla or Sandalwood can also acquire ideal throw at decrease loads (around 6%). Vanillin can darken fragrance oils over time.Volatile citrus/herbal oils may burn off quickly or develop off-smells; consider lower addition temperatures or blending.
Fragrance oils are designed for candle heat, offering consistent, complex scents. Essential oils often burn off quickly, yielding weak scents.Use high-quality, candle-safe fragrance oils for strong throw 2027. Optimal fragrance load is typically 6-10%, up to 12% for some waxes.Pouring temperature (160-185℉/ 71-85℃) is crucial for fragrance binding; too hot causes flash-off, too cool prevents binding 28.
1.2. Wick Configurations and Burn Characteristics
Wick selection is crucial, influencing fragrance release, heat output, and melt pool formation.
Wick Sizing:
Undersized wicks cause tunneling and poor scent throw. Oversized wicks lead to rapid burn, weak scent, excessive sooting, unsafe flame, and mushrooming.
Wick Materials:
- Wick materials (cotton, hemp, wood) affect flame and heat output. Soy wax
- often uses cotton or hemp wicks; wooden wicks suit larger containers, offering a crackle and wider melt pool. Bees wax
- often prefers square braided cotton wicks for consistent burn with its denser nature. Fragrance Influence on Wicking:
- Heavier or vanillin-containing fragrances, and soy wax, may require larger wicks due to increased viscosity or lower melting points to ensure proper melt pool and scent throw.Incorrect wick size is a common cause of weak hot throw. 1.3. Glass Type and Thermal Shock Resistance
- Glass jar integrity is paramount for protection, as flame temperatures (600-800℃) create tremendous thermal pressure.Jars have to face up to rapid temperature fluctuations with out cracking. ASTM F2179 Standard:
ASTM F2179 is a vital protection general for candle glass, testing scratch resistance, temper, and thermal surprise resistance.
