Not all candles are created equal. The difference between a candle that lasts 15 hours and one that lasts 50 is not just the size — it's the type of wax, the wick, the fragrance concentration, and the care with which it was formulated. And the difference between one that smells good and one that smells like chemicals is, simply, the quality of the fragrance oil.
This guide helps you distinguish the worthwhile ones from the not-so-worthwhile ones.
Why are scented candles so different from each other?
There are three variables that determine almost everything:
1. The type of wax
Paraffin is the most common and cheapest. It burns clean but doesn't retain fragrance well and produces more black smoke. Soy wax is vegetable-based, burns slower, retains fragrance oils better, and produces less soot. Coconut wax is the most premium — it burns even cleaner and slower, and has a creamy appearance that looks and feels different. Most luxury candles use soy and coconut blends.
2. The wick
A wick that's too large burns through the wax quickly and produces a high flame that can smoke. A wick that's too small doesn't melt the wax well — it leaves a tunnel in the center and most of the candle never gets used. The correct wick melts the full diameter of the candle within 2-3 hours of use.
3. The fragrance oil
This is the most important difference. Cheap oils have a simple composition and feel flat — they smell the same when lit as when unlit, with no evolution. Quality oils, created by perfumers, have top, heart, and base notes. They change with heat. They feel complex, alive, three-dimensional.
How to tell if a candle is of good quality before buying it
Some indicators:
- The price of the oil: A candle that costs 80 pesos cannot have a quality fragrance. Quality fragrance oil has a real cost.
- Transparency of ingredients: Serious brands mention the type of wax and the origin of their fragrances.
- The cold throw: A good candle smells good even when unlit. If the cold throw is weak or generic, the result when lit won't be any better.
- The visual finish: Uniform surface, centered wick, no bubbles or cracks. These are signs that the production process was careful.
How to use a candle for best performance
First burn — the most important: Let the candle burn until the liquid reaches the full edge of the jar. This can take between 2 and 4 hours depending on the diameter. If you extinguish it sooner, the wax "remembers" that level and will always form a tunnel in the center.
Wick length: Before each use, trim the wick to approximately 5 mm. A long wick produces a higher flame, more smoke, and consumes the wax faster.
Burn time: Do not use the candle for more than 4 hours at a time. The wax gets too hot and the fragrance volatilizes faster than optimal.
Extinguish correctly: Use a wick snuffer or briefly cover the jar. Blowing it out produces black smoke that deposits on the jar's walls and stains the wax.
Selva Santa Candles
At Selva Santa, we use vegetable wax, cotton wicks, and fragrance oils created by a fine fragrance house in France with over 150 years of history. Our fragrances — Neroli and White Cedar, Verbena and Bergamot, Magnolia and Sea Salt — were formulated as complete olfactory compositions, with top, heart, and base notes. They are not simple aromas.
The result is a candle that evolves as it burns. One that gradually fills the space. One that doesn't overwhelm.
