Direct burning means the oud material itself is ignited and combusts — as with oud incense cones or sticks, which burn themselves once lit. Indirect burning means an external heat source is applied to the oud material, causing it to smoulder and release fragrance without catching fire — as with bakhoor chips on an electric burner or charcoal. The practical difference: direct burning tends to be more accessible and consistent; indirect burning produces a different, often more layered aromatic character and allows more control over the session.
Why This Distinction Matters
Most people who are new to oud fragrance do not think about how the material is being burned — they simply light a cone or place bakhoor on a burner and experience the result. But understanding the difference between direct and indirect burning explains why the same underlying oud material can smell noticeably different depending on how it is used, and why certain formats are better suited to certain purposes.
It also explains something that surprises many people: bakhoor and oud incense cones can share very similar aromatic ingredients, yet produce a different experience. The method of burning is part of why.
The oud material is ignited directly — the material itself combusts and burns to completion. Heat comes from within the material, not from an external source.
Examples: Oud incense cones, incense sticks, raw oud wood chips lit directly.
Equipment: No external heat source required — only a heat-safe holder.
An external heat source is applied to the oud material, which smoulders and releases fragrance. The material is heated rather than intentionally ignited.
Examples: Bakhoor chips on an electric burner plate; bakhoor on charcoal (mabkhara).
Equipment: Electric burner or charcoal setup required.
How Direct Burning Works
In direct burning, the oud material — a cone, stick or raw wood chip — is lit with a flame until it begins to glow, then the flame is extinguished, leaving the glowing ember to burn steadily through the material. This is essentially the same process as burning any incense cone: once lit, the material sustains its own combustion and burns to completion.
The fragrance is released through this combustion process. The temperatures involved in direct burning are generally higher than in indirect methods — the material is undergoing actual combustion — and the aromatic output is consistent and predictable throughout the session. This consistency is one of the main advantages of direct-burning incense cones for domestic use: you get a steady, reliable fragrance output from start to finish without needing to manage the heat source.
The trade-off is control: once a cone is lit, you cannot adjust the temperature or intensity mid-session. The cone burns at its own rate, and the fragrance output is determined by the cone's formulation, not by the user's intervention.
How Indirect Burning Works
In indirect burning, the oud material is placed on or near a heat source — an electric plate or a hot charcoal disc — and the applied heat causes the material to smoulder and release aromatic compounds as vapour and smoke. The material is heated rather than intentionally ignited — brought to the point of smouldering and releasing its aromatic compounds.
This method allows much more control over the session. On an electric burner, you can adjust the heat level to affect fragrance intensity. On charcoal, the heat diminishes over time, changing the aromatic character as the session progresses. You can add more material partway through, remove chips if the intensity becomes too high, or let the session taper naturally as the charcoal cools.
Many experienced bakhoor users find that indirect burning produces a more layered aromatic experience than direct combustion — the slower, applied heat allows the session to develop more gradually, and many find the fragrance reveals different aspects of itself as the session progresses. This is an observation shared among enthusiasts rather than a precise principle, and individual perception varies considerably by product and person.
How the Fragrance Character Differs
The same oud fragrance material burned directly vs indirectly can produce a perceptibly different experience. This is not a precise science, and fragrance perception is highly individual, but there are practical differences that many users consistently observe:
| Aspect | Direct Burning (cones) | Indirect Burning (bakhoor) |
|---|---|---|
| Aromatic consistency | Very consistent throughout the session | Evolves as heat changes — often more layered |
| Intensity | Moderate and controlled | Higher, particularly with charcoal |
| Smoke character | Lighter — material burning cleanly | Denser — material smouldering heavily |
| User control | Low — cone burns at its own rate | High — heat can be adjusted or material added/removed |
| Setup required | None beyond a holder | Electric burner or charcoal |
| Best for | Daily use, beginners, consistent results | Occasions, experienced users, maximum impact |
It is worth noting that “different” does not mean “better.” The consistency and simplicity of direct-burning formats are genuine strengths in their own right — particularly for modern daily home use where friction reduction matters. Many regular oud users find incense cones more practical and pleasurable for everyday burning than the more involved indirect method, and that is a completely valid preference. Neither approach produces a superior result across all contexts — they serve different purposes.

Frequently Asked Questions
Is indirect burning better for high-quality oud?
Many experienced oud users prefer indirect burning for high-quality raw agarwood or premium bakhoor blends, on the basis that controlled lower heat allows more of the material's aromatic complexity to emerge gradually rather than burning through quickly at higher temperatures. This is an observation shared widely among enthusiasts rather than a tested principle, and perception varies considerably between individuals. For most commercially produced incense cones and bakhoor, the difference in experience between methods is subtle rather than transformative.
Can I convert a bakhoor recipe to a direct-burning cone?
Not straightforwardly. Bakhoor blends are formulated for indirect smouldering at relatively low temperatures; direct-burning incense cones require a specific binding formulation that allows the material to sustain combustion cleanly. Converting between formats is a specialist manufacturing process, not something achievable at home by adapting the same blend. If you want both formats, it is easier to source separate cone and bakhoor products.
Does indirect burning produce less smoke than direct burning?
Not necessarily — in practice, bakhoor via indirect burning (particularly on charcoal) often produces more visible smoke than oud incense cones. Charcoal bakhoor in particular generates quite dense, heavy smoke. Electric indirect burning tends to produce moderate, controlled smoke similar to cones. The visible smoke volume depends more on the quantity of material and heat level than on the direct/indirect distinction alone.
Can I do indirect burning with oud incense cones?
In principle, placing a cone on a hot surface without lighting it would technically be indirect application of heat to the cone material. In practice, oud incense cones are not formulated for this use — they are designed to burn via direct combustion and may not release their intended fragrance profile when simply heated. Using them as intended (lit and burning) produces the result they are formulated for.
Is one method safer than the other?
Direct burning (incense cones) involves a self-contained, small combustion source — essentially equivalent to burning a candle. Indirect burning on charcoal involves an open charcoal heat source that reaches higher temperatures and takes longer to cool, which represents a higher practical risk in a domestic setting. Electric indirect burning removes the charcoal risk and is broadly comparable in safety to direct-burning cones. Neither format presents unusual risks when used with normal care and ventilation.
Why does my bakhoor smell different on electric vs charcoal?
The temperature difference between electric and charcoal burning is the most likely explanation. Charcoal typically reaches higher temperatures than an electric plate, which can cause some aromatic compounds to burn off more quickly and adds a slight mineral note from the charcoal itself. Many users find charcoal burning produces a more intense, slightly smokier result; electric burning often delivers a cleaner expression of the bakhoor's own fragrance profile. Both experiences are valid — the “better” one depends on what you prefer.
NUHR Oud Incense Cones
NUHR's oud incense cones use direct burning — self-contained, no equipment required, and designed for everyday domestic use in UK homes. For those ready to explore indirect burning, NUHR's bakhoor collection offers the same genuine oud fragrance base in a format designed for electric or charcoal burners.
- Direct burning: the material ignites and burns itself — as with oud incense cones. No external heat source needed, consistent output, lower intensity.
- Indirect burning: external heat is applied to the material without igniting it — as with bakhoor on an electric plate or charcoal. More control, typically higher intensity.
- The same aromatic material can produce a perceptibly different experience depending on the method used — indirect burning at lower temperatures often allows more aromatic complexity to emerge, though this varies by product and individual perception.
- Direct burning is the lower-friction option for beginners and daily use; indirect burning suits experienced users who want more control over the session.
- Neither method is superior across all contexts — they serve different purposes and preferences.
- Electric indirect burning is comparable to direct-burning cones in terms of safety; charcoal indirect burning involves a hotter, longer-lasting heat source that requires more attention.
- Many regular oud users use both methods — direct-burning cones for daily use, indirect bakhoor for occasions when greater intensity or more control is wanted.
