CSI Wick Lab · 7 cm Jars
When a 7 cm Lavender candle burns well and smells weak, a bigger wick is usually the wrong fix. If you must know, let C2 prove itself blind, at a fixed distance, with heat signs as a veto.

Quick answers — read this first
My 7 cm Lavender candle has a good flame and a correct pool but weak hot throw. Should I increase the wick? Usually no. A pool that already reaches the glass at a sensible depth has put the whole wax surface to work. A bigger wick mainly adds heat to the flame, the pool depth and the glass; any throw it adds commonly comes with soot, carbon or a hot jar.

Is there a safe way to find out? One guarded trial: C1 against C2 at the same 8% load, three candles each, coded so nobody knows which is which, smelled at a fixed 2 m at 1 and 2 hours. Any stop condition on a C2 candle voids its throw result.

What are the stop conditions? Trimmed flame above about 5 cm, a carbon cap on the wick, visible soot or black smoke, or the flame leaning towards the glass. Watched, never touched.

What should I check first? Cure time, room size and airflow, nose fatigue, and whether the candle is weak cold as well as hot. All free. The trial costs ₹1,279.75 of materials; if you own the rest, the C2 pack is ₹94.40.
The short answer
The verdict: usually no. A correct pool plus a good flame is a well-wicked candle; weak throw is more often room, cure, nose or oil than wick.
The permitted experiment: C1 v C2, 3 candles each, identical 8% Lavender, blind-coded throw at 2 m at 1 h and 2 h, burns 2–3.
The guardrails: any C2 candle with a trimmed flame above about 5 cm, a carbon cap, soot or a flame near the glass loses the argument, however good it smells.
The pass: C2 preferred blind in at least 2 of 3 pairs, no stop condition, and a clean full life. Then it is a candidate for this jar, oil and load only.

The guarded wick-up trial: three gates, and most paths say keep C1 Our judgement, not a standard. Stop conditions are observations, never touch tests. Thresholds are commonly cited rules of thumb. Step 0 · rule out the free causes cure time · room size and airflow · nose fatigue cold v hot throw (a separate diagnosis) Step 1 · pour the pair, coded C1 × 3 and C2 × 3 · Lavender 8% · 150 g same wax, jar, pour, cure, room · codes on the base Gate A · any stop condition on a C2 candle, any burn? flame over ~5 cm trimmed · carbon cap soot · flame near the glass yes Void tripped candle struck out; two tripped: keep C1 no Gate B · blind coded throw at 2 m, at 1 h and 2 h: C2 preferred in at least 2 of 3 pairs? no No real gain keep C1; look at room, cure or load yes Gate C · full life to about 1 cm left, no stop condition? no Heat fails late keep C1; a hotter wick bought the throw yes C2 is a candidate for this jar, oil and load only In our judgement most weak-throw candles with a correct pool exit on the right. Gate B uses a helper who codes the candles; assessors never know which wick they are smelling. Glass is watched, never touched.
The guarded trial as a flowchart. A bigger wick has to clear three gates in order: no stop condition, a blind preference, and a clean full life. Every exit on the right means keep C1. The gates and the 2-of-3 rule are our judgement; flame height is a commonly cited rule of thumb, not CSI data.

Straight answer
My 7 cm Lavender candle has a good flame but weak hot throw. Should I increase wick size even though the melt pool already looks correct?
Usually no. Hot throw comes from fragrance evaporating off the heated melt pool, and yours already reaches the glass at a sensible depth with a good flame, so the whole surface is already working. A bigger wick in the same 7 cm jar mostly makes the flame taller, the pool deeper and the glass hotter; it may release fragrance a little faster, but the price is commonly soot, carbon on the wick and heat you cannot sell. So check the free causes first: cure time, room size and airflow, nose fatigue, and whether the candle is weak cold as well as hot. If you still want to know, run one guarded trial: three candles on your current wick (C1 in this example) and three on one rung up (C2), all at the same 8% Lavender, smelled blind, coded, at a fixed 2 m, at 1 and 2 hours. Any C2 candle with a trimmed flame above about 5 cm, a carbon cap, soot or a flame near the glass voids its result, however good it smells. Only a C2 that is preferred blind in at least 2 of 3 pairs, never trips a stop condition and passes the full life is a candidate.
One line: a correct pool has already done the wick's job; a bigger wick can only buy throw with heat, so it must prove the throw blind and the heat clean.
Before the trial, buy nothing. The four free checks below solve many weak-throw candles. If they don't, the only purchase for the trial is Eco C2, 10 wicks for ₹94.40, in stock on 29 September 2026.
Eco C2 10 — ₹94.40

Why the answer is usually no

The wick's job is to melt the surface. Yours already does. Throw is a different job.

Think about what the wick controls. It controls how much heat goes into the candle, and so how wide and deep the pool is and how big the flame runs. Once the pool reaches the glass at a sensible depth (about 0.5–1 cm is a common target), the surface area releasing fragrance is as large as this jar allows: about 31.17 cm² on a 6.3 cm inside, on our 0.35 cm wall assumption. A bigger wick cannot make that surface larger. It can only make the pool hotter and deeper, and the flame bigger.

A hotter pool may release fragrance somewhat faster, and makers do sometimes report a stronger room with a larger wick. The problem is what comes with it. Commonly: a taller flame, more carbon on the wick (mushrooming), soot on the glass and in the room, a deeper pool as the candle burns down, and a hotter jar in the final third. Some of that may even be what you are smelling: a hotter, sootier flame can change how a scent reads. That is why the trial below treats every heat sign as a veto.

What a bigger wick changes in a candle whose pool is already correct
Tendencies commonly reported by makers · not CSI data · the reason the answer is usually no
Changes Direction Good for throw? Cost
Pool width None: it already meets the glass No gain —
Pool depth and temperature Up Possibly a little Deeper pools late in the burn; more heat in the lower third
Flame height Up Not directly Soot, flicker, flame nearer the glass
Carbon on the wick Up No; a capped wick can smoke Mushrooming, debris in the pool
Burn time per candle Down No Fewer hours for the customer from the same 150 g

The more common reasons a well-burning candle smells weak are elsewhere: the room is large or ventilated, the candle was burned before it cured, the tester has been smelling it for an hour, or the oil or load is not giving what you expected in this wax. How a 7 cm surface limits a big room is the surface-area post; how to decide whether it is cold throw or hot throw that is weak is the cold-versus-hot diagnosis.

Argued against our own interest: the easiest thing for us to sell you is a pack of bigger wicks. For a candle with a correct pool and a good flame, it is, in our judgement, the purchase least likely to fix weak throw and most likely to create a heat problem you then have to test out again. Try the free checks first; many weak-throw questions end there.

Four free checks before any trial

Every one of these can make a good candle smell weak, and none of them is sold by the pack.
1
CureSoy commonly needs a cure before hot throw is judged. The Lavender page states no cure time in the text we captured; the 25 of 102 CSI oil pages that do say 48–72 hours for soy, and many makers test at day 3, 7 and 14. If you judged it at day 2, judge it again at day 7 and 14 before touching the wick.
2
RoomA 7 cm candle has a small pool. Test in a closed room of known size, with fans and AC off: a worked example is a 10 m² bedroom with a 3 m ceiling, 30 m³. Ceiling fans and AC can both spread and dilute scent, and draughts make a flame flicker. If it fills a bedroom but not a living room, the candle may be fine.
3
NosePerceived strength drops with continuous exposure. The person who poured the candle and sat with it for an hour is the worst judge. Step out for fresh air and come back, or use someone who walks in fresh.
4
Cold versus hotIf the unlit candle is also faint, the wick is not the first suspect: look at oil, load and cure. If it is strong cold and weak hot, that is its own diagnosis, in the cold-strong, hot-weak post. A strong cold throw does not predict a strong hot throw.

Also confirm the pool really is correct. Measure its depth at 3 hours near the wall; confirm it meets the glass all round by burn 2 or 3; and note the trimmed flame height. If the pool is actually shallow or leaves a ring, you have an under-melt, not a throw problem, and the order of operations changes: see the catch-up rule. If the pool is deep and fast, your wick may already be on the large side, and bigger is the wrong way.

Load is a lever too, but it is a different post
Lavender at 8% sits mid-range on its page's 6–10%. Going to 10% adds 3 g of oil a candle (₹16.20 at the 100 g price), and more oil does not raise throw in step with load; at the top it can make a flame smaller. Whether to change the scent input before the heat input is argued in the 10 cm load-first post; the principle carries to 7 cm.

The stop conditions that void a throw gain

A wick that smells stronger and burns worse has not won. It has changed the question.

Write the stop conditions down before you light anything, so a pleasing smell cannot argue you out of them later. In this trial they apply to every C2 candle, every burn, through the full life. If any one trips, that candle's throw scores are struck out. If two of the three C2 candles trip, C2 is out.

Stop conditions · observed at 1 h, 2 h and end of session
Our judgement built on commonly cited rules of thumb · all by eye and ruler; the glass is never touched
Stop condition How to observe it Why it voids a throw gain
Trimmed flame above about 5 cm Ruler held behind the jar at eye level, photo from the side Many makers use about 2.5–5 cm as a practical range; above it, heat and soot rise
Carbon cap (mushroom) at the end of a session Photo of the wick tip before you snuff it Commonly linked to over-wicking; caps can drop debris and smoke
Soot on the glass or black smoke Look into the jar from above; check the inside wall with a torch A dirtier burn is not a better product
Flame leaning towards or near the glass Watch from above; note distance flame-to-wall Flames near glass are a common cause of jar stress
Pool deeper than about 1 cm at 3 h (early burns) Skewer at the wall, marked Deep early pools usually get deeper lower down

If you want a number for glass temperature, it needs a non-contact thermometer; CSI does not list one, so say so in your notes rather than guessing by hand. The black matte jar in this worked example makes soot on the wall harder to see; check from above with a torch. Heat questions where the throw is already strong are the hot-glass step-down post, and how a stronger smell can mask a poor burn is the over-wick masking checklist.

Mistake: accepting a C2 candle because "it smells amazing, and the flame is only a bit big". What happens: "only a bit big" in burn 2 is often "too big" in the lower third, and customers do not trim as carefully as you do. Fix: stop conditions are binary. Tripped is tripped.

Blind, coded, fixed distance: the throw protocol

If you know which candle has the bigger wick, you will smell the bigger wick.

This is the smallest protocol that gives a fair answer to one question: does C2 smell stronger than C1 in this jar at this load? A fuller method for objective hot-throw testing is the objective hot-throw post; here is the version sized for a six-candle trial.

1
Code the candlesA helper writes a random three-digit code on each base and keeps the key sealed. You and your assessors see only codes.
2
Pair themThe helper makes three C1-and-C2 pairs and decides which of each pair burns first. You never learn the order.
3
One candle, one closed room, one sessionBurn one coded candle at a time in the same closed room (or two matched rooms, swapping each session). Fans and AC off, door shut. Air the room fully between sessions.
4
Fixed distance, fixed timesMark a spot 2 m from the candle. Assessors walk in from fresh air at 1 hour and at 2 hours, stand on the mark for about 30 seconds, and score on a simple scale you fix in advance (for example 0 none, 1 faint, 2 clear, 3 strong). The scale is yours; it is not a measurement.
5
Compare within pairsFor each pair, which code scored higher? Use burns 2 and 3 (after cure), not burn 1. Two assessors are better than one; three are better still.
6
Only then unseal the keyStrike out any C2 session that tripped a stop condition, then count: C2 preferred in at least 2 of 3 pairs is a preference. Anything less is noise.
Why 2 m and not "the room"
A fixed mark stops the assessor walking towards the candle until they smell it. 2 m is our worked-example distance; use whatever suits your room, but keep it the same for every session. Fatigue is real: the fresh walk-in matters more than the exact distance.

Running the six-candle trial

One variable: the wick. Everything else is the same candle, poured on the same day.

Pour all six from one melt: Lavender at 8% of total weight (12 g of oil + 138 g of wax per 150 g candle), CSI 464 from one bag, jars from one batch, same pour temperature, same stir, same cure. Three candles on C1 (your current wick, the control) and three on C2. Cure all six the same number of days; we would wait about a week and score burns 2 and 3.

Per candle: ₹211.52 on C1, ₹215.06 on C2 (₹64.80 of Lavender, the wax, ₹70.80 of jar, the wick). From nothing, ₹1,967.80; if you own everything but C2, ₹94.40. Costs are worked examples and exclude labour, freight, packaging and GST. The real cost is time: burns 1–3 on six candles are 18 sessions of about three hours, one candle per room at a time, before full life begins.

Burn every candle in still air, trim to about 5–6 mm before each burn, and log at 1 hour, 2 hours and the end of each session: pool width and depth, trimmed flame height against a ruler, carbon on the wick, soot, flame-to-glass distance, and the throw score from the coded assessment. At about 2.5 hours by the rough one-hour-per-2.5 cm rule, a 3-hour session is long enough for the pool to settle.

After the trial: what each result means

Many trials end with the smaller wick and a better answer about the room.
Trial outcomes · our judgement, labelled
Read after burns 2–3, then after full life for any C2 still in the running
What happened Decision Where to look next
C2 trips a stop condition in 2 or 3 candles Keep C1 The throw gain, if any, was bought with heat. Room, cure, load
No stop conditions; blind preference for C2 in 0 or 1 of 3 pairs Keep C1 No real gain. The candle is room-limited or oil-limited (surface-area post)
No stop conditions; C2 preferred in 2 or 3 pairs C2 goes to full life Watch the lower third; stop conditions still apply to about 1 cm left
C2 passes full life cleanly C2 is a candidate For this jar, Lavender and 8% only; re-test any other oil
C1 candles show a ring or shallow pool you had missed Not a throw question An under-melt; bracket for pool first (the catch-up rule)

If C2 wins, it wins narrowly: in this jar, with this oil, at this load. It is not "the 7 cm wick". If you sell the same jar in heavier oils, those need their own brackets; if you sell it in lighter oils, C2 may be too much for them. The bracket-closure rule for production is the adjacent-sizes post.

Mistake: ending the trial at burn 3 because C2 "clearly won". Why it fails: a bigger wick that wins at the top is the kind of wick more likely to run hot near the base, where heat commonly builds. Fix: Gate C is not optional. Take the winning C2 candles to about 1 cm left, with every stop condition still in force, and the calendar in the full-life post.

What to buy, and what to skip

Four items for the trial, chosen on page statements, price and stock on 29 September 2026. CSI publishes no wick-performance or throw data, so nothing is ranked on results. Oil candle counts are per 150 g candle at 12 g (8%) and 15 g (10%).

1
fragrance oil · herbal/aromatic · the oil in the question
Lavender Fragrance Oil
The page states "Recommended fragrance load 6-10% for candles" and describes "fresh lavender top notes, herbal green mid notes, and soft musk base". 8% is mid-range and inside CSI 464's "up to 10%". The text we captured states no cure time or wick advice. Every size is in stock on 29 September 2026; the 50 g and 100 g are both ₹5.40 a gram, so the 100 g covers six trial candles (72 g) and leaves 28 g. Honest note: one of the Lavender reviews on this page, a 4-star one, praises its hot throw; reviews are general, not a test of your candle, but they are a reason to look at your room, cure and nose before your wick.

wick · the trial rung, not the answer
Eco Candle Wicks — Thick (C2)
The one rung up from C1 in CSI's range; the page states no size or jar range in the text we captured. Buy the 10-pack for a trial, never a production pack: C2 has to clear three gates before it earns your candles, and in our judgement most weak-throw candles with a correct pool do not clear them. Argued against our own interest: C2 costs ₹3.54 more per candle than C1, and if the trial says keep C1 you will have bought 7 spare C2 wicks you may never use. The C1 10-pack is out of stock on 29 September 2026; C1 20-pack is in stock.

jar · CSI's 7 cm listing for the worked example
Black Matte Glass Jar
The page states "fill weight of 200 ml", "Height 8 cm width 7 cm" and "Its durability allows it to withstand high heat", with no temperature figure. We read 7 cm as the outside and pour a labelled 150 g worked-example fill; 200 ml to the brim is roughly 172 g–180 g of wax by the common 0.86–0.9 rule of thumb, so confirm with a weighed test pour. With no heat figure on the page, pour CSI 464 at the low end of its range and pre-warm clean jars (our judgement). Limitation for this test: black matte glass hides soot on the wall and the pool edge from the side, so every Gate A check is made from above; for a pure test, the Clear Glass Jar with Golden Lid (150 gram) shows more. Buy black if black is what you will sell.

Candle Wick Trimmer
Gate A reads trimmed flame height, so every coded candle starts every burn at the same length. The page says "Trim your wick to 1/4 inch before every burn" (about 6 mm). Argued against our own interest: at ₹588.82 it is the dearest of CSI's trimmers; sharp scissors and a ruler work, and the cheaper Candle Wick Cutter is ₹177.00.

What not to buy: Cotton Braided Wicks (₹120.00 for 10) for more throw in a 7 cm jar: its page describes it for candles over 8 cm, two rungs above C1. A C2 production pack before all three gates: the price per wick is the same as the 10-pack. Lavender 1 kg (₹5,221.00) to "push" throw: it is only ₹0.18 a gram cheaper than the 100 g, and more oil is not a wick answer. A second oil "to compare" during the trial: that is a second variable.

The CSI principle
Never buy throw with heat.
A correct pool means the wick is doing its job. If a bigger wick smells stronger, it must prove it blind and burn clean to the bottom; otherwise the answer is in the room, the cure or the oil.
"If you know which candle has the bigger wick, you will smell the bigger wick."

Why trust this guide

CandleMakingSuppliesIndia sells the wicks, oil, jars and wax named here, and does not sell finished candles. This page still tells you that a bigger wick is usually the wrong purchase for weak throw, that a clear jar is a better test jar than the black one in our example, and that you should sell on your current wick until any trial finishes.

Every price was verified on CSI's live store on 29 September 2026, and 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. Load, temperature, jar and trimmer wording is quoted from the product pages; where a page is silent in the text we captured, we say so.

The gates, the 2-of-3 rule, the 2 m mark, the scoring scale, the 0.35 cm wall and the 150 g fill are our judgement or worked examples; flame height, pool depth and melt-pool times are commonly cited rules of thumb; what a bigger wick does is a tendency; CSI publishes no wick-performance or throw data.

Frequently asked questions

Will a bigger wick make my candle smell stronger?
Sometimes a little, because the pool runs hotter, but if the pool already reaches the glass it usually costs more heat, soot and carbon than it gains. Check cure, room and nose first, then test a bigger wick blind with stop conditions.
Why is my candle hot throw weak when the melt pool is full?
Common causes are a short cure, a large or ventilated room, nose fatigue, or the oil and load in that wax. A small 7 cm pool also has a limited surface. The wick is rarely the first suspect when the pool is correct.
How do I test candle hot throw fairly?
Code the candles so assessors don't know which is which, burn one at a time in the same closed room, walk in from fresh air, and score at a fixed distance at 1 and 2 hours after the candle has cured.
How tall should a candle flame be?
Many makers use about 2.5–5 cm as a practical range for a trimmed flame. Above that, soot and heat commonly rise. Trim to about 5–6 mm before each burn.
What fragrance load should I use for lavender in soy wax?
The Lavender page states 6–10% for candles, and CSI 464 states up to 10%. Many makers test 6%, 8% and 10%; the maximum is not automatically the strongest.
How long should I cure a lavender soy candle before testing throw?
The Lavender page states no cure time in the text we captured. CSI oil pages that do state one say 48–72 hours for soy; many makers score at day 3, 7 and 14.

Non-price figures: load is a percentage of total candle weight (150 g at 8% = 12 g oil + 138 g wax). The 150 g fill is a worked example; the Black Matte page states "fill weight of 200 ml" and "Height 8 cm width 7 cm" with no heat figure; the 0.86–0.9 ml-to-grams factor is a rule of thumb; the 0.35 cm wall is an assumption; pool area = π r² on the inside radius. Ceilings as the pages state (CSI 464 up to 10%; Lavender 6–10%): formulation limits, not regulatory ones. Flame height (about 2.5–5 cm), pool depth (about 0.5–1 cm) and melt-pool time (about an hour per 2.5 cm) are commonly cited rules of thumb. The gates, the 2-of-3 rule, the 2 m mark, the scoring scale and the 10 m² room are editorial judgement and worked examples. Costs exclude labour, freight, packaging and GST. Diwali 8 November 2026 is a calendar fact.
