Short answer: Aluminium is replacing glass because it is safer, more durable, lighter to transport and superior across its full lifecycle.
Material choice now defines performance as much as fragrance.
Why Candle Jar Material Matters
The vessel determines:
-
Safety
-
Heat behaviour
-
Breakage risk
-
Environmental footprint
-
Visual presence
Material is structural, not decorative.
Aluminium vs Glass
| Feature | Aluminium | Glass |
| Breakage | Extremely low | High |
| Heat resistance | Excellent | Moderate |
| Weight | Lightweight | Heavy |
| Shipping emissions | Lower | Higher |
| Recyclability | Infinite | Limited |
| Longevity | Lifetime | Often discarded |
Safety and Heat Performance
Aluminium distributes heat evenly and withstands high temperatures without fracturing.
Glass is vulnerable to:
-
Thermal shock
-
Hairline cracks
-
Breakage during transit
For refill systems, aluminium provides long-term structural reliability.
Durability and Transport
Glass candles account for a large share of shipping damage in the candle industry.
Aluminium:
-
Does not shatter
-
Requires less protective packaging
-
Reduces replacements
-
Lowers carbon cost per unit
Environmental Impact
Aluminium can be recycled indefinitely without quality loss and holds one of the highest recycling values globally.
When reused through refill systems, it becomes a true circular material.
This is why Lunaire builds its Forever Jars from aluminium - to support longevity rather than disposal.
