CSI Wick Diagnosis · Acceptable Flame
Almost any wick looks good in the first ten minutes, and a big one looks better than a correct one. Here are the seven criteria that separate a dramatic flame from one you can sell, the photo grid that proves it, and the side-by-side test that settles it.
7 criteria
height, growth, stability, smoke, mushroom, pool depth and glass, on three candles in every third · CSI live pricing, October 2026
Quick answers — read this first
How do I tell an impressive flame from a commercially acceptable one? Watch it for four hours, not four minutes, in still air after a 5–6 mm trim. An acceptable flame stays inside your height band (2.5–5 cm is a common rule of thumb), grows no more than about 1 cm from hour one to hour four, holds a steady teardrop, gives no visible smoke, carries only a small carbon tip, keeps the pool no deeper than about 1–1.5 cm and keeps the glass under a limit you set. An impressive flame usually fails on growth, flicker, smoke or depth.

Isn't a big, lively flame a sign of strong throw? Not reliably. It is a sign of a lot of fuel being drawn up the wick. Some of that becomes scent, some becomes heat and soot. Throw is a separate test.

What do I do if my "beautiful" candle fails? Make one candle per wick with the same formula and compare them side by side: the current rung against one CSI rung down (Cotton Braided → C2 → C1, or a C1 pair). Three candles each, burned to the end, judged in the top, middle and bottom thirds against criteria written down before burn 1.

What does that cost? From C2, the Eco C1 20-pack (₹118.00) covers the comparison including a C1-pair contingency. From Cotton Braided, add a C2 10-pack: ₹212.40. CSI has no half-sizes between these wicks. Buy nothing for production until all three candles of one rung pass.
The short answer
The difference: impressive is how a flame looks in the first few minutes. Acceptable is how it behaves at hour four, in the bottom third, in an ordinary room, on every candle you sell.
The seven criteria: height inside your band; growth of no more than about 1 cm from hour one to four; a steady flame in still air; no visible smoke; a mushroom no wider than your limit; pool depth no more than about 1–1.5 cm; glass under your own written limit. Rules of thumb and in-house limits, not industry standards.
The proof: a photo grid from a fixed camera position at hours 1, 2, 3 and 4, with a ruler and a white soot card, for three candles per wick, every third of the jar.
If it fails: test one CSI rung down beside the current wick, three 200 g candles each, 4-hour sessions to about 1 cm from the bottom. Approve only when every candle passes every criterion in every third.

The grid is a worked example with illustrative values; your own limits, written down before the first burn, decide. Note that A passes the glass check: in the top third the glass often reads fine, which is why the full jar has to be tested.

Straight answer
How do I distinguish a visually impressive candle flame from a commercially acceptable and controlled flame?
By time, conditions and consistency, not by looks. Almost any wick looks good in the first ten minutes, and a big wick looks better than a correct one: taller, brighter, livelier, with a pool that races to the glass. That is the impressive flame. A commercially acceptable flame is one that, after a 5–6 mm trim and in still air, stays inside your height band (2.5–5 cm is a common rule of thumb), grows no more than about 1 cm between hour one and hour four, burns as a steady teardrop without dancing or sputtering, gives no visible smoke, carries a carbon tip no wider than your limit, keeps the pool no deeper than about 1–1.5 cm and keeps the glass under a limit you set with your own non-contact thermometer. It must do that on three candles, in the top, middle and bottom thirds of the jar. If your favourite flame fails, test it against one CSI rung down with the same formula. The plainer flame is very often the one you can sell.
One line: judge the flame at hour four and at the bottom of the jar, against seven written criteria, on three candles; "impressive" usually means one rung too strong.

What an impressive flame is actually showing you

A flame is a fuel gauge. A big one is telling you how much fuel it is pulling, not how well it is burning it.

A candle flame burns vapour. The wick draws liquid wax and fragrance up by capillary action, the heat vaporises it, and the vapour burns where it meets oxygen. A larger or more absorbent wick draws more fuel, so the flame is taller, brighter and hotter, the pool spreads faster, and for a while the room smells stronger. All of that reads as "impressive". The cost shows up later: a deeper pool that feeds the wick even harder, more carbon collecting on the tip, flicker as the flame outgrows the air around it, and the point where the flame draws more fuel than it can burn cleanly, which you see as smoke and black marks.

Impressive flames persuade for three reasons: people judge in the first half hour, while the wick is fresh; movement and a fast pool read as quality; and a hotter pool lifts throw early, so the oversized candle often wins a quick sniff test. Whether that throw is worth the soot and heat is a separate question, and the masking question has its own post; this cluster's large flame, weak throw covers the opposite case.

A controlled flame looks plainer: a steady teardrop that rises a little as the pool forms, then holds. The pool reaches the glass on the second burn and stays shallow, and the tip stays small. Nothing about it stops a scroll; almost everything about it is what a stranger's home needs.

Safety first, plainly: a tall, smoking or leaning flame, a flame close to the glass, or a flame low in the jar near the base is a safety problem before it is a quality problem. Stop that burn, let the candle set, trim, and relight only to test. Never judge glass heat by touch. Use your own non-contact thermometer at the same marked points every time; CSI lists no non-contact thermometer, and our Pen Thermometer is for wax. The "Safe for hot pour up to 85°C" wording on our 150 g jar pages is a pour limit, not a burn rating. No wick, wax or criterion makes a candle "safe" or "soot-free", and you should not claim either on a label.

The seven criteria for a controlled flame

Write the limits down before the first match. Limits chosen after the burn always fit the candle you liked.

None of these is an industry standard, and CSI publishes no flame, soot or glass-temperature data for any wick or oil. They are the criteria most makers converge on, written as an in-house protocol. The starting limits are rules of thumb or our judgement; you set your own and keep them.

Seven criteria · impressive versus controlled
Measured after a 5–6 mm trim, in still air, at hours 1, 2, 3 and 4 · starting limits are labelled rules of thumb or in-house examples, not standards
Criterion How to measure An impressive flame often shows A controlled flame shows Starting limit (yours to set)
1. Height Ruler behind the candle, not touching; photo level with the flame Above 5 cm by hour three or four Inside the band at every check 2.5–5 cm (common rule of thumb)
2. Growth Hour-four height minus hour-one height Climbs all session Settles in the first hour, then holds No more than about 1 cm
3. Stability Watch 30 seconds in still air, then a 10-second video Dancing, leaning, sputtering, tip splitting A steady teardrop that recovers within seconds if disturbed No repeated sputter or lean in still air
4. Smoke Watch the tip; white card held briefly above the flame Visible puffs or a thin trail; grey card No visible smoke; card no darker than your approved reference None visible during burning
5. Mushroom Photo of the tip beside a ruler at hour four, before trimming A carbon ball wider than the wick A small glowing tip Your width, e.g. about 3 mm
6. Pool depth Bamboo skewer midway between wick and glass; wet length Deep and still deepening Reaches the glass, stays shallow About 1–1.5 cm at hour four (rule of thumb)
7. Glass Your own non-contact thermometer, same marked points, hour four, every third Rising sharply lower in the jar Under your limit in all three thirds Your own written figure; flame never near the wall

Two notes on reading the table. Height alone is a weak test. A 4 cm flame that holds steady can be fine, and a 3 cm flame that grew from 2 cm and is smoking is not; the cluster hub, flame fine at hour one, 3 cm and smoking by hour three, is built on exactly that point. Criteria interact. Growth, depth and mushroom usually move together on an oversized wick. Smoke with a normal pool points elsewhere: a long wick, a draught or the oil. If you need to turn these readings into a diagnosis, the six-measurement diagnosis sheet gives the scoring rule; this page is about where the pass line sits.

An eighth rule sits over the seven: consistency. A flame is acceptable only if it meets every criterion on three candles, in each third of the jar. One beautiful candle and two smoky ones is a failed wick, not an average pass. Change the wax, oil, load, dye or jar and the flame you approved is a different flame.

Why dramatic flames fail in customers' homes

Your test bench is the kindest place that candle will ever burn.

On the bench you trim, keep the fan off and stop after a sensible session. At home the candle burns under a ceiling fan through a long evening, is relit untrimmed the next day, and keeps going into the bottom third. A flame that is already at the top of its band on the bench has no margin for any of that. That is why the ranking below separates how a candle is burned from how it was made: you can write care instructions for the first group, but only reformulation fixes the second.

Cause ranking · why an impressive flame turns into a complaint
Ranked by how often each turns a lively bench flame into a problem at home (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. Wick too strong for the jar (making: wick size) Full pool very early, pool deepening past about 1–1.5 cm, flame climbing with depth, fast wax loss Your candle beside one rung down, same formula, both trimmed, still air; log at 1/2/3/4 h Step down one CSI rung; three candles each, full life ₹118.00 (C1 20-pack, from C2)
2. Long burns (burning: session length) Fine at two hours, growing and smoking at four or five Extend one session to four hours; does it pass at hour four? Test at the longest session you expect; care label as a complement, not a cure Nothing
3. No trimming (burning: wick length) Tall, flickering flame and a carbon cap from the first minute of a relight Relight one candle at about 10 mm untrimmed: does it settle within the hour? A wick that tolerates a missed trim; trimming instructions on the label A cutter from ₹177.00
4. Fans, AC, open windows (burning: the room) Flicker, lean, one-sided pool, soot streaks on one side Same candle, fan on versus fan off Burn-location advice; a wick with margin so a draught doesn't push it over Nothing
5. The lower third (burning and making: heat build-up) Fine for the first burns, taller and hotter lower down Burn to about 1 cm from the bottom and compare thirds Choose the wick on the bottom third, not the top Test time, not money
6. Heavy oil, high load or dark dye (making: formula) Bigger mushroom and more smoke in one scent or colour than another on the same wick Same wick and jar: your oil against a lighter oil, or dyed against undyed A per-fragrance or per-colour wick, or a lower load within both ceilings e.g. Citrus Lemon 2 × 50 g ₹340.00

Causes 2, 3 and 4 are customer behaviour, and they are real: many Indian homes burn candles under a ceiling fan or near an AC vent, and few people trim. A wick that is fine only when trimmed and burned in still air for two hours is not commercially controlled; it is controlled by you. The test for that margin is in the untrimmed-wick tolerance post, and airflow has a no-cost check in the flicker-or-airflow post. Cause 5 is why criterion 7 and the bottom third matter so much; the late-jar mechanism is the late-burn heat hub, and black marks that appear only near the end are the soot hub.

Cause 6 is a tendency, not CSI data. Vanilla-rich, resinous and dark gourmand oils commonly build more carbon than light citrus or herbal oils, and higher loads can move a wick either way (fine with lavender, huge with vanilla). No CSI oil page gives soot or flame data in the text we captured. If you want a light-oil control, Citrus Lemon's page states "candles (6-10%)" and 16 g costs ₹48.00 at the 100 g price.

Don't sell the photo. If the candle in your product photo has a tall, lively flame, you are setting the customer's expectation at the exact point where the wick is least controlled. Photograph the flame you approved, at the height it holds at hour two. Don't hide a strong wick behind instructions either. "Trim to 5 mm before every burn and never burn longer than two hours" on a label is a sign the wick has no margin. Care instructions complement a controlled wick; they do not create one.

The photo comparison grid

If you can't put two photos side by side and see the difference, your camera position is wrong, not your eyes.

"Slightly taller" and "a bit of smoke" drift between burns; photos taken the same way don't. The grid (one row per candle, one column per check time) makes criteria 1 to 5 comparable across candles and weeks, and it is your evidence when a stockist asks how you approved the candle.

How to shoot it so the photos mean something
Fix the camera: phone on a stand or a stack of books at flame height, the same distance every time (mark the spot with tape). Fix the background: a plain dark card behind the flame for height, so the outline is clear; a plain white card for soot. Ruler: stood behind the candle, not touching it, centimetres facing the camera. Lighting: room lights as they were for the first session; don't switch on a bright lamp for one photo. Video: 10 seconds at hour four shows flicker better than any still. Name every file with candle, wick, burn number and hour, so the grid builds itself.

The soot card, honestly. Holding a white card briefly above the flame (a few seconds, high enough not to scorch it, never touching the flame) shows soot you can't see in the air. It is a comparison tool, not a measurement: compare cards taken at the same height, and keep the card from the wick you approved as your reference.

Keep a reference candle. When a wick passes, keep one unburned candle and its grid. If a later batch looks "more impressive" than the reference, something changed: start with the batch-comparison post.

The side-by-side test and the approval rule

One candle per wick shows a difference. Three per wick shows whether you can rely on it.

If your current candle fails the criteria, the test is a comparison: the impressive candle against the same formula one CSI rung down, made on the same day. It uses the series' default test candle, labelled: 200 g at 8% = 16 g fragrance + 184 g wax (load as a percentage of total weight), in your jar. Keep your own fill if it differs and scale the grams.

1
Write the seven limits and the approval rule firstCopy the criteria table, put your own figure in every row, and sign and date it. If you approve on "it looked fine", the impressive candle will win every time.
2
Make the candles identical except for the wickSame wax, oil lot, load, fill and pour temperature (your wax page's figure: Premium Coconut Soy Wax CSI 468 states "Pour Temperature 58°C – 60°C" and "Fragrance Load Up to 13%"), poured the same day, every wick centred. Core test: your current wick and one rung down, three each, 6 candles. If you start on C2, pour three C1-pair candles as a contingency in case single C1 tunnels: 9 in all.
3
Cure them together and burn them togetherCitrus Lemon's page, for example, says to cure soy candles 48–72 hours before burn testing; many makers also test at day 7 and 14. Burn all candles in the same still room, spaced well apart so the flames don't heat each other, with the room temperature written down.
4
Run 4-hour sessions and shoot the gridTrim to 5–6 mm, light, and record each criterion at hours 1, 2, 3 and 4 with the photos. Weigh before and after. Let each candle cool and set fully before the next session. Stop any session where the flame smokes continuously or approaches the glass, and record it as a fail.
5
Burn to the end and judge each third separatelyMark the jar into thirds and stop at about 1 cm of wax left (a common rule of thumb). Worked example: at 6.8 g an hour, the 180 g above the floor takes about 26.5 hours, roughly 7 four-hour sessions. Most failures of impressive wicks appear in the lower third, so don't stop early.
6
Apply the rule, then chooseA wick passes only if all three candles meet all seven limits in all three thirds. If both rungs pass, choose the one with the steadier flame and the shallower pool that still reaches the glass from burn two. If none passes, move to a pair or to the formula, and ask us on WhatsApp if you need a step CSI doesn't list.
The approval rule (ours, labelled)
A wick is approved for a formula when three candles each meet all seven written limits at every check in the top, middle and bottom thirds, in 4-hour sessions in still air after a 5–6 mm trim. One smoking session, one hot-glass reading or one flame outside the band fails that wick for that formula. No averaging, no "mostly fine". This is an in-house protocol, not an industry standard, and it applies only to the wax, oil, load, dye and jar you tested.

Worked example (illustrative, not CSI data). Two candles, same formula. Candle A on the current wick: 3.2 cm at hour one, 5.6 cm at hour four (+2.4 cm), sputtering, a 5 mm cap, a 1.9 cm pool, 9.0 g an hour. Candle B one rung down: 2.6 to 3.0 cm (+0.4 cm), steady, a 2 mm tip, a 1.0 cm pool, 6.8 g an hour. A fails six of seven criteria; B passes all seven in the top third, which earns it the rest of the jar, not approval. Notice the side effect: at those rates, the 180 g above the floor lasts about 20.0 hours in A and 26.5 in B, about 6.5 hours more. The controlled candle also burns longer, a claim the burn-hour post shows how to make honestly.

The CSI wick buy list and the step to production

Our wick range is short. That keeps the comparison simple, and it means we have to be honest about the gaps.

CSI's sized, tabbed wicks are three rungs: C1 → C2 → Cotton Braided. "One rung down" means Cotton Braided → C2, C2 → C1, or a C2 pair → a C1 pair. There is no sized, tabbed wick between C1 and C2 or between C2 and Cotton Braided, no smaller sized, tabbed wick than C1, and only one wooden-wick listing, with no widths (the wooden-wick post covers that case). The untabbed braided rolls and the Eco Candle Wicks Loose (page: "designed specifically for 2 inch diameters") are cut-to-length constructions, not half-sizes. If your impressive candle is one rung too strong and the next rung tunnels, we would rather say so: ask us on WhatsApp, test a pair, or make the adjustment on the fragrance side.

Argued against our own interest: you may not need new wicks. If your candle passes all seven criteria at hour four in still air and only fails under a fan, your fix is placement advice, and your spend is nothing. And because C1 (₹5.90), C2 (₹9.44) and Cotton Braided (₹12.00) cost the same per wick at every pack size, a bigger pack buys stock, not savings. Stepping C2 → C1 saves ₹3.54 a candle, which is a side effect, never the reason.

The step to production quantity

Once a rung passes, production wicks = candles × wicks per candle × (1 + a defect allowance). Worked example, labelled: 200 single-wick candles a month with a 3% allowance is 206 C1 wicks; buy 2 × 100 + 20 = 220 for ₹1,298.00 (14 left over). A 500-pack (₹2,950.00) costs the same ₹5.90 a wick and ties up ₹1,652.00 more cash. If C2 passes instead, 210 C2 wicks are ₹1,982.40. The same month needs about 36.80 kg of wax at 184 g a candle. Reorder point = daily use × your lead time + safety stock; CSI publishes no lead times, so ask on WhatsApp before you set yours. A later change of wick lot or supplier is a formula change: compare it against your reference candle (same pool, more mushrooming: is it equivalent?).

Don't buy 1,000 wicks for a flame that looked good on day one. The 1,000-packs are ₹5,900.00 (C1), ₹9,440.00 (C2) and ₹12,000.00 (Cotton Braided), with no per-wick saving on any of them. An impressive first evening is the least informative result you can get. Buy the 20-pack, pass three candles to the bottom, then buy by the month.
Diwali is 8 November 2026, 32 days from 7 October 2026. A full comparison (a 3-day cure, then about seven daily 4-hour sessions) takes about 10 days.

The two smallest rungs on CSI's ladder, and the most common "one rung down" when an impressive flame fails your criteria. In the text we captured, the page states no length, width or jar-diameter range, so neither is the right wick for your jar until three candles pass. The page also claims "minimal soot or smoke": read that as a description of a correctly sized, trimmed wick, not a promise about yours. C1 is ₹5.90 a wick and C2 ₹9.44 at every pack size. Argued against our own interest: the C1 20-pack (₹118.00) covers the whole C2 → C1 comparison including the pair contingency, and no bigger pack is cheaper per wick.

wick · pre-tabbed · the top rung
Cotton Braided Wicks Ready Made
CSI's largest sized, tabbed cotton wick. The page says it is "engineered for large-diameter candles exceeding 8 cm" and claims "optimal flame height, preventing tunneling"; it also states "Height of the wick is 10.16 cm". If a jar of 8 cm or less wears this wick and the flame looks spectacular, the page's own positioning already suggests C2 as your first comparison. It is ₹12.00 a wick at every pack. Limitation: there is no tabbed size between it and C2. If C2 tunnels and this one dances and smokes, the realistic options are a C1 or C2 pair, or a change on the fragrance side, not a half-size we do not sell.

tool · makes criterion 5 measurable · trimming
Candle Wick Cutter | Candle Wick Trimmer
Every criterion assumes the same starting trim, about 5–6 mm. Without it you are comparing wick lengths, not wicks. CSI lists two Candle Wick Cutters (3 cm and 5.5 cm blades) and a Candle Wick Trimmer whose page says "Trim your wick to 1/4 inch before every burn" and "Perfect Length: Ensures optimal flame height" (the page's claim; trimming sets the starting point, it does not size a wick). Argued against our own interest: scissors that reach the wick will do for a home test. Buy a cutter when you need the same cut on nine candles in a row.

accessory · removes a false fail · centring
Wick Centering Device (Pack of 5)
An off-centre wick leans, heats one wall and flickers, and it will fail criterion 3 for reasons that have nothing to do with wick size. These bars have one 4 mm hole ("Hole Dia 0,15" (4mm)") and fit openings the page gives as "less than 4"" (about 10 cm), so they hold a single wick. For the C1-pair contingency you need a holder with two slots; the Steel Wick Holder (Set of 5, ₹250.00) states a "3-hole layout" but no spacing, so measure before relying on it. Limitation: a centring bar holds the wick while the wax sets. It cannot fix a wick that was bent or a tab that was glued off-centre.

wax · for the test candles · the page claims low soot
Premium Coconut Soy Wax CSI 468 (Flakes Form)
If you are building a range and want one wax for all your test candles, this page states "Fragrance Load Up to 13%", "Pour Temperature 58°C – 60°C" and "Clean, stable burn with low soot output". Attribute that last line to the page: a wax claim cannot make an oversized wick controlled, and an impressive flame in a "low soot" wax is still an impressive flame. Your 200 g candle at 8% is 16 g oil + 184 g wax, well inside the page's ceiling. Argued against our own interest: if your candles are already made in another wax, test in that wax. Switching wax and wick together means you will never know which one changed the flame.
Pack Price Stock For this test
500 g ₹325.00 In stock top-up with the 1 kg for 6 candles
1 kg ₹650.00 In stock 2 x 1 kg for all 9 candles
5 kg ₹3,185.00 In stock production, after approval
10 kg ₹6,370.00 In stock production, after approval
1 kg + 500 g = ₹975.00 covers the six core candles. Buy 1 kg — ₹650.00

Skip for now: any 500- or 1,000-pack before approval; a new wax or oil "to calm the flame" while the wick is unresolved (one variable at a time); the 5.5 cm cutter and the trimmer if the ₹177.00 cutter reaches your wick; and a non-contact thermometer from us, because we don't list one: use your own.

The CSI principle
Sell the flame you can repeat, not the flame you can photograph.
Seven criteria, written first; three candles per wick; every third of the jar. From C2 the comparison costs ₹118.00 in wicks.
"The candle that looks best in the first ten minutes is often the one that fails at hour four."

Why trust this guide

CandleMakingSuppliesIndia sells the wicks, wax and tools named here, not finished candles. This page still tells you a plainer flame is often the better product, that you may need no new wicks at all, that our bigger wick packs cost no less per wick, and that our range has no half-sizes and one wooden width.

Every CSI price was checked on the live store on 7 October 2026, with stock checked per pack: the Eco C1 10-pack is out of stock and is not used, and every other item priced here is in stock on that date. Page wording is quoted and attributed, including the Eco wick page's "minimal soot or smoke" and the CSI 468 page's "low soot output".

The height band (2.5–5 cm), pool depth (about 1–1.5 cm), 1 cm wax floor and trim length are common rules of thumb. The seven limits, the approval rule, the worked-example values and the production figures are labelled judgement or examples. Fragrance effects are tendencies, not CSI test data. For bulk pricing, GST invoicing, and MSDS and IFRA documentation on request, message us on WhatsApp at +91 7397976926.

Frequently asked questions

What does a good candle flame look like?
A steady teardrop, inside your height band (about 2.5–5 cm is a common rule of thumb), that settles in the first hour and then grows little, with no visible smoke, a small glowing tip and a pool that reaches the glass without getting deep. It should look the same at hour four and near the bottom of the jar.
Is a bigger candle flame better for scent throw?
Not reliably. It can lift throw early, but it brings soot, a deep pool and hot glass. Test throw separately, at a flame that passes your criteria.
Why does my candle flame dance and flicker?
Usually a draught (fan, AC, open window), a long or mushroomed wick, or a wick too strong for the jar. Trim to 5–6 mm and burn in still air; if it still dances after the first hour, compare it with one wick size smaller.
How tall should a candle flame be in a jar candle?
Many makers use about 2.5–5 cm as a practical range (a rule of thumb, not a standard). Growth and steadiness matter more than one reading: a flame that climbs by more than about 1 cm over four hours, or smokes, needs attention.
How do I test a candle wick before selling?
Write your limits first, then burn at least three candles per wick in 4-hour sessions, trimmed to 5–6 mm, in still air, to about 1 cm from the bottom, judging the top, middle and bottom thirds separately. Every candle must pass every limit.
What wick is one size smaller than C2?
At CSI, Eco Candle Wicks Thin (C1); the 20-pack is ₹118.00 (₹5.90 a wick) and the 10-pack is out of stock on 7 October 2026. There is no sized, tabbed wick between C1 and C2; for a finer step, ask us on WhatsApp.
Impressive or controlled?
Write seven limits, shoot the grid, and compare your candle with one CSI rung down on three candles to the end.
From C2 the wicks cost ₹118.00; from Cotton Braided, ₹212.40. If neither rung gives you a controlled flame in your jar, 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 sets the criteria that separate a visually impressive flame from a commercially acceptable one, with a cause ranking for why dramatic flames fail at home, a photo comparison grid, a side-by-side test with an in-house approval rule, a CSI wick buy list and a production step.

Customer reviews: The six reviews at the top of this page are genuine, published Judge.me reviews left by CSI customers on the product pages named on each card — Citrus Lemon Fragrance Oil, Clear Glass Jar with Golden Lid (150 gram), Eco Candle Wicks, Luxury Soy Wax Chunks for Jar / Container Candles, Premium Coconut Soy Wax CSI 468 (Flakes Form) For Container Candles.

Non-price figures: the 200 g test candle at 8% (16 g oil + 184 g wax, load as a percentage of total weight) is the series default, labelled. Wax ceiling as the page states (CSI 468 up to 13%), a formulation limit, not a regulatory one. Trim length 5–6 mm (one trimmer page says 1/4 inch); height band 2.5–5 cm, pool depth about 1–1.5 cm, growth of about 1 cm, the 1 cm wax floor (about 20 g in the worked example) and about one hour per 2.5 cm of diameter (7 cm ≈ 2.8 h) are common rules of thumb or judgement. Diagram and worked-example values (heights, depths, 9.0 and 6.8 g/h) are illustrative. The seven limits and the approval rule are an in-house protocol, not a standard. Costs are materials only and exclude labour, freight, packaging and GST. Diwali 8 November 2026 is a calendar fact.
