CSI Wick Diagnosis · Double Wick
Two large flames and a hot jar tempt you to pull one wick out. Usually the better first move is to fix the spacing and shrink both, because one wick in a wide jar either tunnels or burns tall in the middle. Here is the four-arm test that settles it.

an Eco C1 20-pack plus a Cotton Braided 10-pack: the smaller pair and a fair single-wick arm · CSI live pricing, October 2026
Quick answers — read this first
My double-wick candle has two large flames and gets too hot. Should I make both wicks smaller instead of removing one? Usually, yes. Two smaller flames still spread the heat across the pool; one flame alone has to melt the whole width from the centre, so it commonly tunnels or has to burn tall to keep up. Rule out the free causes first (trim, draught, spacing), then test a smaller pair beside your current pair and one single-wick arm, three candles each, to the end.

What do I check first? Trim both wicks to 5–6 mm, burn four hours in still air, and measure the spacing: wicks set close together commonly share one very hot centre; wicks close to the glass heat the walls. If the flames settle and the heat drops, it was trim, air or placement.

What is "both smaller" at CSI? Cotton Braided pair → C2 pair → C1 pair. There is nothing tabbed between C1 and C2, so from a C2 pair the only smaller pair is two C1s.

What does it cost? From a C2 pair: a C1 20-pack (₹118.00) for three C1-pair candles, plus a Cotton Braided 10-pack (₹120.00) for a fair single-wick arm, ₹238.00 together.
The short answer
The diagnosis: two large flames and a hot jar mean the pair is supplying more fuel than the jar can carry, or something is feeding it: long wicks, a draught, or wicks placed too close together or to the glass.
Reduce both first: a smaller pair keeps two heat zones and full-width melting with less total fuel. Removing one wick concentrates everything in the centre and commonly tunnels.
Check spacing: in a 9.3 cm-inside jar, a starting point (judgement) is each wick about halfway between centre and wall: 4.65 cm apart, 2.325 cm from the glass. Measure yours; our Steel Wick Holder states no spacing.
The test: 12 candles of 400 g at 8%: current pair, smaller pair, one Cotton Braided centred, one C2 centred, three each, 4-hour sessions, to the end, judged by third.

Straight answer
My double-wick candle has two large flames and excessive heat. Should I reduce both wick sizes rather than remove one wick immediately?
In most wide jars, yes: reduce both first, and test removing one only as a fair comparison. Heat follows fuel. Two large flames are burning a lot of wax every hour, and that heat goes into the pool, the glass and the air above. A smaller pair cuts the total fuel while keeping two heat zones spread across the jar, so the pool can still reach the walls. One wick changes the geometry, not just the size. A single flame in the centre of a 9.3 cm-inside jar has to melt 67.93 cm² on its own; a modest wick commonly tunnels, and a wick big enough to keep up commonly runs tall and concentrates the heat in the middle. Rule out the free causes first: trim both wicks to 5–6 mm, burn in still air, and measure where the wicks sit, because wicks too close together share one hot centre and wicks close to the glass heat the walls, whatever their size. Then test: your current pair, the next smaller CSI pair (C2 pair → C1 pair; there is nothing tabbed in between), one Cotton Braided centred and one C2 centred, three candles each, 4-hour sessions, to the end, judging top, middle and bottom separately. Two tall flames and a hot jar are a reason to stop the burn first.
One line: trim, still the air and measure the spacing (free); then test a C1 pair against your C2 pair and two single-wick arms, three candles each, to the end. The wicks cost ₹238.00.
The "reduce both" test, priced: Eco C1 20-pack (₹118.00) for the smaller pair, Cotton Braided 10-pack (₹120.00) for the single-wick arm, and a 40-sticker sheet (₹100.00) to fix the spacing. In stock on 7 October 2026; the C1 10-pack is not.

Why two smaller flames usually beat one

The question isn't one wick or two. It is how much fuel, and where the heat lands.

Your symptom, restated: a double-wick candle, both flames large, and the candle running hotter than you are comfortable with: the glass, the pool, the air above it. You haven't said when it starts, so check whether it is hot from the first burn (this post) or fine at first and hot only lower in the jar, which is late-burn heat and belongs to the double-wick-overheats-later post (6975).

Think of the jar as a pool that needs melting to the edge and a glass wall that needs to stay within your limit. Two wicks each melt a zone around themselves; in the worked-example jar each serves about 33.96 cm² of the 67.93 cm² pool. When the pair is too strong, both zones are too hot, the pool goes deep, and the flames grow on the extra fuel. The fix that keeps the geometry is a smaller pair: less fuel per wick, the same two zones. One wick must melt the whole 67.93 cm² from the centre. A wick that is comfortable alone in a 7 cm jar commonly leaves a ring of wax here; a wick big enough to reach the glass commonly does it with a tall flame and a very hot centre. Removing a wick doesn't cool the candle so much as move the heat.

That is the logic behind "reduce both first", and it is a tendency, not a law: some jars do burn well on one strong wick, which is why the test below includes a fair single-wick arm rather than dismissing it. The choice between one larger wick and two smaller ones for a new jar is a design question with its own post, one larger wick or two smaller; here the pair already exists and is too strong.

Safety first, plainly: two large flames and a hot jar are a safety problem before a quality problem. Stop the burn, let the candle set, trim both wicks and remove any carbon before relighting. Never judge glass heat by touch; use your own non-contact thermometer at the same marked points each time (CSI lists none; our Pen Thermometer is for wax), and set your own written limit before testing. The "Safe for hot-pour up to 85°C" line on some of our jar pages is a pour limit, not a burn rating. Flames leaning towards each other or towards the glass mean stop. No wick change makes a candle "safe", and nobody should promise you one.

Before you change wicks: the causes, ranked

A pair has twice the chances of a long wick and twice the reach of a draught.

The ranking is our judgement for two large flames with excessive heat, ordered so the free checks come first.

Cause ranking · double wick, two large flames, too much heat
Ranked by likelihood and cost to test (judgement) · signs are common observations, not CSI burn data · ₹ from CSI live pricing, 7 October 2026
Cause What you'd see Discriminating test Fix Cost
1. Long wicks or mushrooms (burning: trimming) Both flames tall from lighting; carbon caps; smoke when caps glow Set candle, both trimmed to 5–6 mm, still air, 4 h Trim both before every burn Nothing
2. Draught (burning: room) Flames leaning one way, one side melting faster, soot streaks Same candle, fans and AC off, away from vents Placement; care-card line Nothing
3. Wicks too close together (making: placement) Flames leaning in, one very hot central pool, rim cooler Measure spacing; compare a re-spaced candle Move them outwards to your chosen spacing ₹100.00 (stickers)
4. Wicks too close to the glass (making: placement) Hot spots on the wall beside each wick; fast edge melt Measure wick-to-wall; glass reading by each wick Move them inwards ₹100.00
5. Both wicks oversized (making: wick size) Full pool fast, pool deeper than about 1–1.5 cm (rule of thumb), fast wax loss, heat even with good spacing Current pair beside the next smaller pair, three candles each Reduce both: C2 pair → C1 pair ₹118.00 (C1 20)
6. Heavy oil or high load (making: formula) Bigger, sootier flames in one scent on the same pair Same pair and jar, a lighter oil or unscented control Per-fragrance wick, or load tested within both ceilings Your own oil
7. Long sessions (burning: duration) Fine at 2–3 h, hot by 5–6 h Log at 1/2/3/4 h; stop at 4 A maximum session on the label, tested to Nothing

Causes 3 and 4 are why this post insists on measuring before buying: a pair that is merely too close together can look exactly like a pair that is too big. The deep version of spacing-versus-size is in 42xx: wicks too close, one hot centre and wicks too close to the glass. Cause 7 matters more for multi-wick candles; whether they should carry a shorter maximum session is 6977's question.

The spacing check: measure before you blame the size

Two millimetres of guesswork in the holder can look like a whole wick size in the jar.

Measure your jar's inside diameter at the fill line, then the centre-to-centre distance between the wicks (s). For two wicks on a diameter, each wick's distance to the wall is r − s/2, where r is the inside radius. That is geometry, not a burn prediction. In the worked example, a 10 cm outer jar with an assumed 0.35 cm wall is 9.3 cm inside, r = 4.650 cm. A common starting point (our judgement, a place to start testing, not a rule) puts each wick about halfway between the centre and the wall, so s ≈ r.

Spacing in the worked-example jar · 9.3 cm inside
Geometry from the formulas above · what you'd see is a common tendency, not CSI data · measure your own jar
Wicks set Spacing s Each wick to the glass Commonly seen
Too close 3.0 cm 3.15 cm One shared hot centre; flames leaning in; rim melts last
Starting point (s ≈ r) 4.65 cm 2.325 cm Two zones that meet in the middle; even melt
Too wide 6.5 cm 1.40 cm Flames near the walls; hot glass beside each wick; a cooler strip between

Tools, honestly: our Steel Wick Holder page says it "fits single, double, or triple wick setups" and fits jars "up to 9 cm wide", but it states no hole spacing, and the worked-example jar is wider than that. Our Wick Centering Device has one 4 mm hole, so it holds a single centred wick. For a pair in a 10 cm jar, mark the two positions on a card template cut to the rim, fix the tabs with wick stickers at those marks, and hold the wicks upright while the wax sets. If your pair turns out to be far off the starting point, re-space first and re-test before changing wick size: one variable at a time. The full spacing method for a 9 cm jar is how far apart two wicks should sit.

A curved jar changes the answer as it burns
If your jar is curved or tapered, the inside diameter changes with height, and so do r and the wick-to-wall distance. Measure at the top, middle and bottom of the fill. A jar that narrows towards the base brings the wicks relatively closer to the glass late in the burn: one reason heat can climb lower down (container shape and late heat in double-wick candles).

The four-arm test: pair, smaller pair, two singles

Four arms answer the title's question directly: smaller pair, or one wick?

The worked example, labelled: the reader's 10 cm jar (9.3 cm inside), a 400 g fill at 8% = 32 g fragrance + 368 g wax (load as a percentage of total weight; weigh your own fill), Luxury Soy Wax CSI 464 (page: "Fragrance Load Up to 10%", "Pour Temperature 80°C – 90°C"), current pair C2 + C2 at the starting spacing. If your pair is Cotton Braided, shift every arm up one rung.

1
Fix the spacing, then pour twelve identical candlesSame wax lot, oil lot, fill and pour temperature, poured the same day. Pairs at the same measured spacing on every candle; singles dead centre. Label A1–3 (C2 + C2, the control), B1–3 (C1 + C1), C1–3 (one Cotton Braided), D1–3 (one C2).
2
Cure togetherApple Cinnamon's page, for example, says "cure 48-72 hours" for soy; many makers also test at day 7. All twelve the same age.
3
Burn 4-hour sessions in still airCandles well apart so they don't heat each other. A 9.3 cm pool needs about 3.7 hours by the one-hour-per-2.5 cm rule of thumb, so four hours is a valid session. Trim every wick to 5–6 mm first.
4
Log at 1, 2, 3 and 4 hEach flame's height, pool depth at the centre and beside each wick, pool width, mushroom, a soot card, glass readings at marked points (beside each wick and between them), and grams lost per session.
5
Gate 1, after the top thirdDrop any arm that smokes continuously, exceeds your glass limit, or still leaves a wax ring at the wall by the end of burn three. In the illustration, arm D (one C2) stops here.
6
Gate 2, at the floorBurn the survivors to about 1 cm of wax left (a common rule of thumb), judging middle and bottom thirds separately. Approve with the rule below.
Reading the four arms · illustrative worked example
Consumption figures are illustrative, not CSI data · 340 g burned before the floor is a worked example · your log decides
Arm Wicks g/h (illustrative) 4-hour sessions to the floor What the illustration shows
A (control) C2 + C2 10.0 9 Fast, deep pool; glass over your limit by mid-jar: fails
B C1 + C1 7.6 (24% less fuel) 12 Full width from burn two; cooler glass: the candidate
C 1 Cotton Braided 7.0 13 Reaches the glass only with a tall flame; hot centre: borderline
D 1 C2 4.8 stopped at gate 1 A wax ring at the wall after three burns: tunnels
The approval rule (ours, labelled)
An arm passes when all three candles, in the top, middle and bottom thirds, at 4-hour sessions in still air: reach the glass by the end of the session from burn two; keep every flame inside your band (2.5–5 cm is a common starting point) with no visible smoke; keep the pool within your depth limit (about 1–1.5 cm is a common rule of thumb); keep every glass reading under the limit you wrote before burn one, measured, never felt; and finish with about 1 cm of wax left. One fail in any candle fails the arm. This is an in-house protocol, not an industry standard. If B and C both pass, prefer the one with the cooler glass and steadier flames; for most wide jars that is the pair.
Don't do this: don't pull one wick out of a finished candle and call it a test: the remaining wick is off-centre and the result means nothing. Don't change size and spacing at once. Don't test only the smaller pair without the current pair beside it. Don't approve on the top third: a pair that is fine early can still overheat low in the jar (double-wick candles that get dangerously hot near the bottom). And don't print "trim both wicks every hour" to rescue a pair that is simply too strong.

The CSI pair ladder, buy list and production

Our wick range is short. For pairs, that means one smaller pair below C2, and none below C1.

CSI's sized, tabbed wicks are three rungs, C1 → C2 → Cotton Braided, so the pair ladder is Cotton Braided pair → C2 pair → C1 pair. There is no tabbed wick between those rungs, nothing smaller than C1, and one wooden width. If a C2 pair is too hot and a C1 pair won't reach the glass, the step you need is one we don't sell: try the spacing, the load or a single-wick arm, or ask us on WhatsApp and we will tell you plainly.

Argued against our own interest: if your wax and oil are already on the shelf, the whole test is ₹338.00. CSI 464 is flat per kilo from 1 kg, so the 5 kg (₹2,537.00) saves nothing over five 1 kg packs (₹2,537.00), and for a 4,416 g need four 1 kg packs plus a 500 g (₹2,289.60) is the cheaper buy. Apple Cinnamon is flat at ₹4.74 a gram from 50 g, so four 100 g bottles (₹1,897.44) cost less than the 500 g (₹2,371.80) for a 384 g need; its page states "6-10% for soy wax candles". And a C1 pair is ₹7.08 a candle cheaper than a C2 pair: a side effect, never the reason.

The step to production quantity

Once a pair passes on three full-life candles, production wicks = candles × wicks per candle × (1 + a defect allowance). Worked example, labelled: 80 double-wick candles a month with a 3% allowance is 165 C1 wicks; 100 + 50 + 20 = 170 cost ₹1,003.00 and leave 5. The same month needs 29.44 kg of wax at 368 g a candle. Record the approved spacing on the batch sheet alongside the wick: in a pair, spacing is part of the specification, and a change of holder is a change of formula (what to revalidate after moving to two wicks). CSI publishes no lead times; confirm yours on WhatsApp before setting a reorder point.

Diwali is 8 November 2026, 32 days from 7 October 2026. The four-arm test takes up to about 16 days (a 3-day cure and up to 13 daily sessions), so pour this week if a festive double-wick batch depends on it.

Eco Candle Wicks — Thin (C1) and Thick (C2)
The core of "reduce both": from a C2 pair, the next pair down is two C1s. In the text we captured, the page states no length, width or jar-diameter range for either, so the pair that passes your full-life test is the right one, not a chart. C1 costs ₹5.90 and C2 ₹9.44 a wick at every pack, so a C1 pair is ₹11.80 a candle against ₹18.88 for C2. Argued against our own interest: the C1 20-pack (₹118.00) covers three C1-pair candles with 14 spare; nothing bigger is cheaper per wick. The C1 10-pack is out of stock on 7 October 2026.

Cotton Braided Wicks Ready Made
"Remove one wick" deserves a fair test, and leaving one C2 alone in a wide jar isn't fair: it is the weakest single option. Cotton Braided is CSI's strongest tabbed single wick, and its page says it is "engineered for large-diameter candles exceeding 8 cm" (a 9.3 cm inside diameter qualifies on the page's wording), with "Height of the wick is 10.16 cm" and a claim of "optimal flame height, preventing tunneling". ₹12.00 a wick at every pack. Limitation: one big flame puts all the heat in the centre of the jar; if it reaches the glass only by running tall, it has swapped two hot flames for one.

Steel Wick Holder (Set of 5)
The page says "3-hole layout fits single, double, or triple wick setups" and "Fits most jar diameters (up to 9 cm wide)", and tells you to "insert the wick(s) in the slots". It states no hole spacing, so measure the distance between the outer holes before you trust it for a pair. Argued against our own interest: for the 10 cm worked-example jar this holder is outside the fit the page states, so don't buy it for that jar; use stickers and a card template you mark yourself. For jars up to 9 cm it can hold a pair, at whatever spacing its holes happen to give: measure, then decide whether that spacing is the one you want to test.

Skip for now: the Steel Wick Holder for any jar wider than the 9 cm its page states; 500- or 1,000-wick packs before a pair passes the bottom third; a third wick "to spread the heat" (more wicks add fuel: three-wick candles are 6918); and a new oil while the pair is unresolved. If your jar is the 12 cm kind that may need three, the large three-wick redesign is the next read.

The CSI principle
In a wide jar, heat is a fuel problem and a placement problem. Fix the placement for free, then shrink both wicks before you take one away.
For two large flames and a hot jar: trim, still air, measure the spacing; then a C1 pair against your C2 pair and two single-wick arms, three candles each, to the end. The wicks cost ₹238.00.
"Taking a wick away doesn't cool a candle. It moves the heat to the middle."

Why trust this guide

CandleMakingSuppliesIndia sells the wicks, wax, stickers, holders and jars named here, not finished candles. This page still tells you to fix spacing before buying wicks, not to buy our Steel Wick Holder for a jar wider than its page states, that our bigger wick packs cost no less per wick, and that there is no tabbed wick between C1 and C2.

Every CSI price was checked on the live store on 7 October 2026, with stock checked per pack: the Eco C1 10-pack and the 100-sticker sheet are out of stock and are not used; every other item priced here is in stock on that date. Page wording is quoted and attributed, including the Steel Wick Holder's "up to 9 cm wide", the Apothecary jar's "Safe for hot-pour up to 85°C", the Cotton Braided page's "exceeding 8 cm" and the Eco page's claims.

The 5–6 mm trim, the 2.5–5 cm flame band, the 1–1.5 cm pool depth, the 1 cm wax floor and the hour-per-2.5 cm guide are common rules of thumb. The 0.35 cm wall, the starting spacing, the 400 g fill, the consumption figures, the session counts, 80 candles a month and the 3% allowance are labelled examples or our judgement.

Frequently asked questions

Why is my double wick candle so hot?
Usually both wicks are too strong for the jar, too long, too close together or too close to the glass, or a draught is feeding them. Trim, burn in still air and measure the spacing before changing wick size.
Should I remove one wick from a double-wick candle?
Not as a first fix. One centred wick has to melt the whole width alone, so it commonly tunnels or burns tall. Test a smaller pair first, with a strong single wick as a comparison arm.
How far apart should two candle wicks be?
A common starting point is each wick about halfway between the centre and the wall, so the spacing is about the inside radius. That is a place to start testing, not a rule: measure the jar inside and check heat by each wick.
What is smaller than a C2 pair at CSI?
A C1 pair. There is no tabbed wick between C1 and C2. The C1 20-pack is ₹118.00 (₹5.90 a wick) and covers three double-wick test candles; the 10-pack is out of stock on 7 October 2026.
How do I check if my candle jar is too hot?
Never by touch. Use your own non-contact thermometer at the same marked points each session, against a limit you set before testing. CSI does not sell one.
Can I use a steel wick holder for a 10 cm jar?
CSI's Steel Wick Holder page says it fits jars up to 9 cm wide and states no hole spacing. For a 10 cm jar, mark positions on a card template and fix the tabs with wick stickers.
Double wick · two large flames · too much heat
Fix the trim, air and spacing first; then shrink both wicks before you remove one, three candles per arm, to the end.
From a C2 pair the wicks for the four-arm test cost ₹238.00. If a C2 pair runs hot and a C1 pair won't reach the glass, tell us on WhatsApp, and we will say plainly what we stock between them, and what we don't.

Editorial standards & sources
About this guide: part of CSI's cluster "Flame Is Too Large" (6901–6920) in the series on large flames, soot, smoke, mushrooming and wick purchase. It covers a double-wick candle with two large flames and too much heat: why a smaller pair usually beats one wick, a cause-ranking table, a spacing check with geometry, a four-arm test with two gates and an in-house approval rule, and a CSI buy list and production step.

Non-price figures: "double-wick", "two large flames" and "excessive heat" are the reader's description (title). The 10 cm jar, 0.35 cm wall (9.3 cm inside, 67.93 cm²), the 400 g fill at 8% (32 g oil + 368 g wax, total-weight basis), the starting spacing s ≈ r and the 3 cm / 6.5 cm comparisons are labelled worked examples; wick-to-wall = r − s/2 is geometry, not a burn prediction. Wax and oil ceilings as their pages state them (CSI 464 up to 10%; Apple Cinnamon 6–10% for soy): formulation limits, not regulatory ones. The 5–6 mm trim, the 2.5–5 cm flame band, the 1–1.5 cm pool depth, the 1 cm wax floor and about one hour per 2.5 cm of diameter (9.3 cm ≈ 3.7 h) are common rules of thumb. The 10.0 / 7.6 / 7.0 / 4.8 g/h figures, 340 g burned, the session counts, 80 candles a month and the 3% allowance are labelled examples; the diagram is illustrative. Costs are materials only and exclude labour, freight, packaging and GST. Diwali 8 November 2026 is a calendar fact.
