My 7.5 cm Jar Works Perfectly with Lavender but the Same Wick Mushrooms Badly with Oud at 10% — Why Does Changing Only the Fragrance Alter the Burn?
शेयर करना
How do I separate them? Three cells on the same wick, two candles each: Woody Oud 8%, Woody Oud 10% (your repeat) and Lavender 10%. Six candles, 54 g of oud, 30 g of Lavender, 816 g of wax, six wicks: ₹877.36 of materials, your jars aside.
What does each result mean? Only Oud 10% caps: it is load in oud; drop to 8% and keep the wick. Both oud cells cap, Lavender 10% clean: it is the oil; give oud its own bracket. Both 10% cells cap: it is load; run at 8% or re-bracket at 10%.
Is 10% too much? It is the top of Woody Oud's stated 6–10% and of CSI 464's "up to 10%", not above them. Top of the range is a limit, not a target.

Two things changed, not one
Write down both candles side by side. Same 7.5 cm jar, same wax, same wick, same pour. Candle one: Lavender at 8%, 12 g of oil in 150 g. Candle two: Woody Oud at 10%, 15 g in 150 g. The oil changed and the load changed, together. In the language of testing, the two are confounded: any difference between the candles could be the oil, the load, or the two acting together, and one pair of candles cannot say which.
It matters because each explanation earns a different fix. If the load is the problem, the cheapest answer is less oil and the same wick. If the oil is the problem, oud needs its own wick, and Lavender keeps its own. If both matter, you may need less oil and a different wick, and you want to know that before you commit a collection to it. Jumping straight to a smaller wick for oud assumes the oil is the cause and that 10% is the right load; both are assumptions.
Why people raise the load for oud in the first place is understandable: a heavier, woodier oil can seem quieter in the room, so they add oil. Whether a stronger dose is buying throw or only carbon is exactly what the design below measures. (The broader question of 8% against 10% on a struggling wick, as a 2 × 2 with a wick step, is the 2 × 2 load and wick test; this page keeps the wick fixed on purpose.)
What oud and a higher load each do to a wick
Mushrooming is a cap of carbon that forms on the tip of a wick as it burns, often looking like a small black knob. It is commonly linked to a wick that is too large for the candle, to heavy fragrance or dye loads, and to long burns; it is a sign that the flame is not consuming everything the wick delivers. It is an observation, not a diagnosis on its own. The two changes in your candle each push that way, as tendencies, not CSI data:
| Suspect | What the page states | Commonly reported tendency | What would show it |
|---|---|---|---|
| The oil: Woody Oud | "rich oud and patchouli heart, settling into warm woody notes, amber, and musk"; "candles (6-10%)"; "Strong throw" | Heavier, resinous or woody oils often need a wick adjustment and are often linked to more carbon than light herbals | Oud caps at 8% as well as at 10% |
| The load: 10% vs 8% | Woody Oud 6–10%; CSI 464 "up to 10%"; Lavender 6–10% | A higher load can make a flame smaller or sootier; more oil does not raise throw in proportion | Lavender caps at 10% too, and oud stops capping at 8% |
| The two together | — | A heavier oil at the top of its range can do what neither does alone | Only Oud 10% caps |
| Neither (the wick) | Eco wick page: no size or jar range stated | A wick at the top of its useful size caps whenever the candle is pushed | Everything caps, even Lavender 10%, and your Lavender 8% was borderline |
Lavender is the right control because its page describes the opposite structure: "fresh lavender top notes, herbal green mid notes, and soft musk base". Light herbal oils often wick more easily (tendency). That is also why Lavender at 10% is the most informative new candle in the set: if even Lavender caps at 10%, load is doing the damage regardless of oil.
The three-cell design, cell by cell
Fix everything that is not the oil or the load: the wick (the C2 your Lavender burns cleanly on, in the worked example), wax bag, jar batch, 150 g fill, pour temperature, cure, room and session. CSI 464's page states "Pour Temperature 80°C – 90°C"; your own 7.5 cm jar's heat wording is whatever its seller states, so pour at the low end and pre-warm clean jars (our judgement). Then pour three pairs:
| Cell | Oil per candle | Wax per candle | Candles | What it isolates |
|---|---|---|---|---|
| Woody Oud 8% (new) | 12 g | 138 g | 2 | Does oud cap at Lavender's load? Contrast 1 with Oud 10% gives the load effect inside oud |
| Woody Oud 10% (repeat) | 15 g | 135 g | 2 | Confirms your observation in a fresh, controlled pour; the anchor for contrasts 1 and 2 |
| Lavender 10% (new) | 15 g | 135 g | 2 | Does load alone cap a light oil? Contrast 2 with Oud 10% gives the oil effect at equal load |
| Lavender 8% (optional control) | 12 g | 138 g | 0 or 2 | Only if your history candle came from a different wax bag, jar batch or season: 24 g of Lavender and ₹288.52 more |
| Total (three cells) | 54 g oud + 30 g Lavender | 816 g | 6 | 6 C2 wicks; your own 7.5 cm jars |
Pouring, curing and burning
Why two per cell, not three? Because this design is a sorting test, not an approval: its job is to decide which single change to make next, and the follow-up test is where you pour three per cell. Two candles protect you from one bad pour; a split pair (one caps, one does not) earns a third candle of that cell before you read the pattern.
Reading six candles: five patterns, five different fixes
| Oud 8% | Oud 10% | Lavender 10% | What it points to | The one change it earns |
|---|---|---|---|---|
| clean | caps | clean | 1 · Load in this oil. Oud handles 8% on this wick; the extra 3 g tips it over | Run oud at 8% (or test 9%) on the same wick, then full life. No new wick |
| caps | caps | clean | 2 · The oil. Oud caps at any load; load alone does not cap Lavender | Give oud its own bracket at your chosen load: current vs one rung down (C2 → C1), 3 candles each |
| clean | caps | caps | 3 · Load in any oil. 10% is too much for this wick in this jar | Make 8% your line load, or re-bracket at 10% for the whole range |
| caps | caps | caps | 4 · The wick. Near the top of its useful size even for Lavender | Bracket one rung down for all oils; check trim and session length first |
| clean | clean | clean | 5 · A one-off. The original oud candle had another difference | Find it: trim, draught, session length, pour; repeat Oud 10% on 3 candles |
Patterns 1 and 3 are the good news: nobody needs a new wick. Pattern 2 is the one the question assumed, and it may well be the answer, but now you know it. Pattern 4 says your Lavender candle was not as comfortable as it looked; its "perfect" burn was near the edge, and the full-pool-in-45-minutes post has the over-wick checks. Pattern 5 happens more often than people expect, because "same wick" rarely meant "same everything".
What the split costs, and what guessing costs
The three-cell split uses 54 g of Woody Oud, 30 g of Lavender, 816 g of CSI 464 and six C2 wicks. The obvious alternative is to guess "it's the oil" and run a wick bracket for oud at 10%: C1 against C2, three candles each, 90 g of oud.
| Line | Three-cell split (this page) | Guess-the-oil wick bracket |
|---|---|---|
| Candles | 6 (three cells × 2) | 6 (two wicks × 3) |
| Woody Oud | 54 g at ₹4.53/g = ₹244.68 | 90 g at the same price |
| Lavender | 30 g at ₹5.40/g = ₹162.00 | none |
| CSI 464 | 816 g = ₹414.04 | 810 g |
| Wicks | six C2 = ₹56.64 | three C1 + three C2 |
| Materials consumed | ₹877.36 | ₹864.82 |
| What it answers | Oil, load, or both, and whether the wick is involved at all | Which of two wicks suits oud at 10%, assuming 10% is right |
The two routes cost about the same. Only one of them can tell you that the cheapest fix was to use less oil. From nothing, the split's cash outlay is ₹1,324.92 (Woody Oud 100 g, Lavender 50 g, CSI 464 1 kg and a C2 10-pack), your jars aside; with wax and wicks on the shelf it is the two oils.
What pattern 1 is worth
If the answer is "load in oud", dropping from 10% to 8% saves 3 g of Woody Oud a candle: ₹13.59 at the 1 kg price (₹67.97 down to ₹54.37 of oil per 150 g candle), or ₹1,359.36 on 100 candles, and needs no new wick. That is a real saving, but do not let it choose the answer for you: if oud at 8% loses the character you sell, the fix is the pattern-2 bracket at 10%, not a weaker candle. Woody Oud is priced at ₹4.53 a gram at 100 g, 500 g and 1 kg alike, so the saving does not depend on buying in bulk.
After the split: the one change each pattern earns
Pattern 1 (load in oud): pour three candles of Oud 8% on the same wick and take them through the full life to about 1 cm left, watching the lower third, where carbon and heat commonly build. If you want to test 9%, it satisfies both readings of the wax ceiling: 9% of total weight is 9.89% of wax weight, under 10% either way, whereas 10% of total is 11.11% of wax weight and 10% of wax is only 9.09% of total. The wax page does not say which basis its "up to 10%" uses.
Pattern 2 (the oil): oud gets its own bracket at the load you choose: current C2 against one rung down, C1, three candles each, full life. CSI's C1 is buyable in packs of 20 and up (₹5.90 a wick; the 10-pack is out of stock on 29 September 2026). There is no sized, tabbed wick between C1 and C2 at CSI; if oud lands between them, we would rather say so. Whether oud should then share a wick group with your other heavy oils is the fragrance-family grouping post.
Pattern 3 (load in any oil): this is a range decision, not an oud decision. Make 8% your house load for the jar, or re-bracket at 10% if the whole line must run at 10%. Pattern 4 (the wick): check trimming and session length, then bracket one rung down for every oil. Pattern 5 (a one-off): repeat Oud 10% on three candles after finding the difference.
Oud in a larger jar is a different opening question (one large wick or two small from day one), and that is the 9 cm oud opening round; the attribution method for sandalwood at 7 cm, which adds an unscented candle, is the three-candle triad.

CandleMakingSuppliesIndia sells the oils, wicks and wax named here, and does not sell finished candles. This page still says that two of five outcomes need no new wick, that the cheapest fix may be less of our oil, and that CSI has no data to say one oud burns cleaner than another.
Every price was verified on CSI's live store on 29 September 2026. Stock was checked per size: the Eco C1 10-pack is out of stock on that date and is flagged; every other size shown is in stock. Oil notes, load ranges, cure wording and wax figures are quoted from the product pages; where a page is silent in the text we captured, we say so.
The three-cell design, the "both of a pair" rule and the pattern readings are our judgement; the carbon-cap and load tendencies are commonly reported, not CSI data; CSI publishes no wick-performance data.

Non-price figures: load is a percentage of total candle weight (150 g at 8% = 12 g oil + 138 g wax; at 10% = 15 g + 135 g). The 150 g fill, the C2 house wick and the 0.35 cm wall are worked-example assumptions. Ceilings as the pages state (Woody Oud and Lavender 6–10%, CSI 464 up to 10%, pour 80–90°C): formulation limits, not regulatory ones; the CSI 464 page does not state the basis of its 10%. Carbon-cap and load effects are commonly reported tendencies. The cell design, the pair rule and the pattern readings are editorial judgement. Costs exclude labour, freight, packaging, jars and GST.
