Why perfumes rest for weeks, candles need time to cure, and handmade incense cannot be rushed. A little story about patience, craftsmanship and the beauty of making things slowly.
A Beautiful Thing Isn't Always Ready When It Looks Finished
There's a peculiar moment in making fragrances when something looks completely finished, yet I know it isn't ready.
A perfume has been blended and poured into its bottle. A candle has cooled, its surface beautifully smooth. A row of handmade incense sticks lies neatly arranged on my worktable.
Everything looks as though the work is complete.
And yet, in each case, there is another ingredient involved. One that cannot be weighed, measured or added from a glass bottle.
Time.
At sense • studio • amsterdam, I create perfumes, perfume oils, candles and Japanese-style incense in small batches. Each format involves different materials, processes and technical considerations. But they all have something in common: the moment I finish making them is not necessarily the moment they're ready to be experienced.
Sometimes, the most important thing I can do is leave them alone.
In Perfumery, Time Reveals the Composition
When I create an eau de parfum, I begin by carefully combining aromatic materials into a fragrance concentrate. The formula may contain dozens of ingredients, from bright citrus oils and delicate floral extracts to woods, resins and naturally derived aromatic isolates.
Every ingredient has its own character and behaviour. When combined, they create something new, but the freshly blended composition doesn't always reveal its final character immediately.
After diluting the concentrate in alcohol, I allow my perfumes to rest for several weeks before their final evaluation. In perfumery, this resting period is often called maceration, although terminology can vary between makers.
During this time, the aromatic materials disperse throughout the mixture, and some interactions and subtle changes can occur. Certain aspects of the composition may become more integrated, while others reveal themselves differently.
I find it particularly interesting to compare a freshly prepared sample with the same fragrance after it has been resting for some time. Sometimes the difference is subtle. Occasionally, it's surprisingly noticeable.
A composition that initially feels a little disjointed may become more harmonious. Or I might discover that a particular ingredient is still too dominant, and the formula needs another adjustment.
Of course, resting isn't a magical process that automatically improves every perfume. A poorly balanced formula won't necessarily become beautiful simply because it's been left untouched.
But allowing a composition time to settle gives me a more informed understanding of what I've created.
A fragrance needs to be experienced not only when it's new, but also after it has had time to develop.
Candles: Fourteen Days of Patience
Candle making introduces an entirely different relationship with time.
At sense • studio, I work with a blend of soy wax and beeswax, combined with my own fragrance compositions. Once the ingredients have been carefully measured, blended and poured, the wax begins to cool and solidify.
Within hours, the candle may look finished. Its surface has set, the wick is in place, and the fragrance is already noticeable.
But the wax continues to develop its structure as it cools and settles. Fragrance performance can also change during the days following production.
For my candles, I allow approximately fourteen days of curing before the final fragrance and burn evaluation.
This is especially important because the fragrance of an unlit candle doesn't necessarily tell us how it will perform when burning.
A beautiful cold throw — the aroma you notice before lighting — doesn't guarantee an equally beautiful hot throw, the fragrance released as the candle burns.
The wax blend, fragrance concentration and wick all influence the experience. Testing helps me understand whether the candle burns consistently, whether the melt pool develops appropriately and whether the fragrance performs as intended.
Sometimes, a candle that looks absolutely perfect still needs a different wick or an adjustment to its formula.
And when I make that adjustment, I need to prepare another batch and evaluate it again.
This is one of the less glamorous realities of craftsmanship. There isn't always a shortcut between creating something beautiful and knowing that it works beautifully.
Incense: Learning to Let Things Dry
Japanese-style perfume incense might be the most delicate example of why certain processes cannot be rushed.
My incense begins as a mixture of finely ground aromatic woods, resins, botanical powders and a carefully developed fragrance composition. These ingredients are combined into a workable dough and shaped into slender sticks without a bamboo core.
Freshly shaped incense is surprisingly fragile. It contains moisture, and the structure needs time to become firm enough for handling and burning.
At sense • studio, the sticks typically dry for approximately one week, depending on their composition and the surrounding conditions.
The drying process needs to happen carefully. If the sticks are handled too soon, they may bend or break. If moisture remains within the material, it can affect how they burn.
Humidity, temperature and airflow all influence the process, so the calendar alone cannot tell me whether a batch is ready.
Once the sticks are dry, I can evaluate their structure, burning behaviour and fragrance.
I find something particularly satisfying about this transformation. What began as a soft, aromatic mixture becomes a slender, almost weightless object that can slowly release its fragrance into the air.
A simple object, carrying a surprisingly elaborate process within it.
Waiting Is Not the Same as Doing Nothing
One of the things I've learned through developing my fragrances is that patience in craftsmanship is rarely passive.
While one perfume is resting, another formulation might be ready for evaluation. While candles are curing, I might be testing a different wick or refining the fragrance composition for a future batch.
And while incense is drying, there are always new ideas to explore, ingredients to study and experiments to document.
Working in small batches allows me to remain closely involved in these different stages. I can observe how the materials behave, compare formulations and make adjustments based on what I discover.
But it also means accepting that I cannot control every part of the process.
Some materials behave differently than expected. A new batch of botanical extract might have a slightly different aromatic character. A formulation that worked beautifully in one experiment might need refinement when prepared again.
And sometimes, the best next step is simply to wait and observe.
That can be surprisingly difficult when you're excited about a new creation and eager to share it.
Yet rushing an evaluation can mean overlooking something important.
Does More Time Always Mean Better Quality?
There's an idea often associated with luxury that the longer something takes to make, the better it must be.
I don't entirely agree.
Time matters when it serves a purpose. Allowing a candle to cure, incense to dry or perfume to rest can be an important part of the process. But leaving a product untouched for months doesn't automatically make it superior.
Fragrance materials can also change in undesirable ways over time. Some delicate aromatic compounds may degrade, particularly when exposed to heat, light or oxygen.
The goal is not to make the process as long as possible.
It's to understand what each material needs.
Sometimes, a relatively short period is sufficient. Other times, a composition needs more evaluation, another adjustment or an entirely new experiment.
For me, craftsmanship is about recognising the difference.
Time doesn't create quality on its own. What matters is knowing when to wait, what to observe and when something is truly ready.
The Beauty of Something Made With Attention
We live in a world where almost everything seems to be available immediately. An idea can become an order within seconds, and the finished product may arrive at our door the following morning.
There's enormous convenience in that, and I appreciate it as much as anyone.
But creating something by hand has introduced a different rhythm into my life.
One where materials have their own requirements, experiments don't always succeed and certain stages simply take as long as they take.
I find that rather beautiful.
Not because waiting is inherently virtuous, or because every handmade object needs to become a philosophical statement.
But because it reminds me that creating something well often involves paying attention to things we cannot immediately see.
The way a fragrance changes after resting. The behaviour of a candle after curing. The transformation of an incense stick as it gradually dries.
These small observations inform the decisions I make as a perfumer and the products I eventually share.
And perhaps that's one of the pleasures of working with fragrance. We are creating something that exists in time. A perfume unfolds on the skin, a candle accompanies an evening, and an incense stick releases its aroma before gradually disappearing.
The experience itself may be fleeting.
Yet so much thought and care can exist behind it.
At sense • studio • amsterdam, that's what making things slowly means to me.
Not taking more time than necessary, but giving every creation the time it deserves.
Frequently Asked Questions
Why does perfume need to rest after blending?
After a fragrance concentrate is diluted in alcohol, a resting period can allow the mixture to become more uniform and its aroma to settle. Some compositions change noticeably over time, while others change very little. At sense • studio, I allow my eaux de parfum to rest for several weeks before their final evaluation.
How long should natural wax candles cure?
Curing recommendations depend on the wax blend and fragrance formulation. Soy-based candles are commonly allowed to cure for approximately one to two weeks before fragrance evaluation. At sense • studio, I allow my soy-and-beeswax candles around fourteen days before final testing.
Why does handmade incense need to dry?
Freshly shaped incense contains moisture that needs to evaporate before the sticks can be handled and burned properly. Drying helps the incense develop its structure and can influence its burning behaviour. My handmade Japanese-style incense generally takes approximately one week to dry, depending on the formula and environmental conditions.
Does perfume get better the longer it ages?
Not necessarily. A controlled resting period can help some newly blended perfumes develop a more integrated fragrance character. However, extended ageing does not guarantee improvement. Aromatic materials can also degrade over time, especially when exposed to unfavourable storage conditions.
