CSI Wick Lab · Multi-Wick Candles · Full Life
A multi-wick candle that passes the first half and runs hot at the bottom needs its bottom levers moved, not its wicks shrunk. Tune wick size for the top, spacing for the middle, and the session cap, stop line and fill for the bottom, in one spec sheet.
3 zones
each tuned with its own lever, one spec sheet per SKU · CSI live pricing, September 2026
Quick answers — read this first
My multi-wick candle is perfect for the first half but very hot near the bottom. How do I fix it without ruining the top? Stop treating the wick as the only lever. Each depth has its own: wick size tunes the top third, spacing the middle third, and the session cap, stop line and fill height the bottom third. Fix the bottom with the bottom's levers first.

What is a life-cycle spec sheet? One page per multi-wick SKU that records, for each third of the candle by weight, which lever was tuned for it, the pass criteria and the evidence. It turns "the wick works" into "this candle works at every depth, burned the way the label says".

Why not just use smaller wicks? A smaller wick cools the bottom and also the top, where your candle currently passes; it commonly brings back a ring in burns 1–3. And if your SKU is already a pair of C1, CSI has no smaller sized, tabbed wick to step to.

What does a retest cost? Often nothing at first: re-burn the lower third of candles you have at a shorter session cap and a higher stop line. A new-pour round of four 500 g candles in CSI's Apothecary jar at 8% Japanese Cherry Blossom on C1 pairs is ₹2,630.42 in materials.
The short answer
The principle: a multi-wick candle is optimised zone by zone. Top third: wick size and count. Middle third: spacing. Bottom third: session cap, stop line and fill height.
The order when the bottom fails: confirm the failing session matched the label; then shorten the session cap; then raise the stop line; then move the wicks a little inward; change wick size last, and re-pass the top if you do.
The spec sheet: jar measurements, fill weight and depth, wax, oil and load, wick build and lot, measured spacing, cure, then three zone rows with lever, pass criteria and evidence, plus the label text.
The honest limit: CSI's smallest sized, tabbed wick is C1, so a pair of C1 has no size step down in our range; CSI lists no non-contact thermometer, and glass heat is never judged by touch.

Straight answer
My multi-wick candle performs perfectly for the first half but becomes extremely hot near the bottom. How can I optimise the wick system across the entire candle life?
Treat the candle as three zones and give each zone its own lever, written into one spec sheet for the SKU. The top third (roughly burns 1–3) is where wick size and count are chosen: the pool must reach the glass with flames in range. The middle third is where spacing shows itself: wicks too close commonly merge their heat, wicks too near the glass heat it as the wall above the pool grows. The bottom third is governed by how long each session runs, where the candle is told to stop, and how much wax sits above that stop line. Your candle passes the top and middle, so its wick size and spacing are probably right for those depths. Fix the bottom with the bottom's levers first: check the failing session was not longer than your label allows, retest the lower third at a shorter session cap, raise the stop line from about 1 cm to about 1.5 cm, and add fill to keep your burn hours if headspace allows. Move the wicks a little inward only if those fail, and change wick size last, because it changes every zone and must re-pass the top. If your SKU is already a pair of C1, CSI has no smaller sized, tabbed wick, so the bottom-zone levers are your main route.
One line: wick size for the top, spacing for the middle, session cap and stop line for the bottom: fix each zone with its own lever.
The first retest costs nothing: re-burn the lower third of candles you already have, at a shorter session and a higher stop line. When the label changes, CSI's Candle Care Stickers Roll is ₹413.00 for 500 (₹0.83 a candle); check the printed wording on the product images first.

Why the bottom of a multi-wick jar behaves differently

The wick is the same at the bottom. Everything around it is not.

As a container candle burns down, the glass above the pool grows taller, absorbs heat from the flames and holds warm air around them; the pool sits nearer the jar's base; and carbon can build on the wicks over many sessions. These are common late-burn tendencies, not CSI measurements, and they are stronger in a wide, multi-wick candle because two or three flames add their heat to the same walls. The result is the pattern in your question: a candle that passes burns 1–3 and the halfway point, then runs a deeper pool, taller flames and hotter glass in its last sessions.

The usual reaction is to step the wicks down. That cools the bottom, and it also cools the top, where your candle currently passes, so the first burns commonly come back with a ring. You trade a hot bottom for a tunnelled top. The two-zone trade-off table for that choice is the 9 cm two-zone scorecard, and the double-wick late bracket is the double-wick-hot-near-the-bottom post. This page takes a different route: it asks which lever governs which depth, so the bottom can be fixed without touching what already works.

The worked example is a two-wick candle in CSI's Apothecary jar: about 9.3 cm inside on our assumed 0.35 cm wall, a 67.93 cm² pool, a 500 g fill at 8% Japanese Cherry Blossom (40 g oil + 460 g wax) in Luxury Soy Wax CSI 464, and a pair of Eco C1 at the cluster's starting spacing (s = r = 4.65 cm). Every figure for your own SKU goes in your own sheet.

Mistake: approving a multi-wick SKU on burns 1–3 and the halfway check. Why it fails: the lower third is where heat commonly builds and where a customer's last sessions happen; on our worked example it is about 107 g of wax and 15.2 hours of burning before the stop line. Fix: no SKU is approved until a candle has burned to its stop line at its labelled session length, with the flames and glass watched, never touched. How far down to burn is the how-far-down post.

Three depths, three levers

Each lever reaches every depth a little. Each depth answers to one lever most.

Split the candle into thirds by weight: with a 500 g fill, about 167 g each. The boundaries are found by weighing between sessions, not by eye, which is why a scale belongs on the spec bench. For each third, one lever does most of the work. The pairing is our judgement, built on how the candle changes with depth; it is a way to decide what to move first, not a physical law.

Which lever governs which depth · our judgement
Worked-example SKU: Apothecary jar, 500 g at 8%, 2 × C1 at s = 4.65 cm · "also moves" = side effects to re-check
Zone Main lever Why this lever Also moves
Top third (burns 1–3) Wick size and count The surface is widest and coolest; reaching the glass is a question of total power Every zone: a size change re-tests the whole candle
Middle third Spacing (wick to wall, wick to wick) Walls above the pool start to heat; how close each flame sits to the glass and to its neighbour starts to matter The top's edge reach (moving wicks inward slows the edge)
Bottom third Session cap, stop line, fill height Heat accumulates within a session and near the base; how long each session runs and where burning ends set how much of that zone the candle meets Burn hours (stop line), label and net weight (fill)

Spacing in numbers. At s = r the two wicks sit 2.33 cm from the glass along the wick line and 5.20 cm from the wall points at right angles to it. Moving them 5 mm closer together puts them 2.58 cm from the glass along the line, a little further from the nearest wall, at the cost of a slower edge in burns 1–3. Geometry, not a burn prediction; the inward-ladder method is the wall-gap trade post.

The bottom levers in numbers. On the worked example, if the SKU loses about 7.0 g an hour (weigh yours) and about 60 g remains at a 1 cm stop line, the candle has about 440 g to burn, about 62.9 hours: 15.7 four-hour sessions or 21.0 three-hour sessions. A three-hour cap does not shorten the candle's life; it shortens each session, which is the part of the bottom zone where heat accumulates. Whether your build passes at that cap is what the retest finds out.

The life-cycle spec sheet, field by field

One page per SKU. If it is not on the sheet, it is not part of the approved candle.

The spec sheet is the record that a multi-wick candle works at every depth, burned the way its label says. Fill it once for the approved build and copy it to every production batch sheet. The fields below are a template; the values shown are the worked example's.

Life-cycle spec sheet · template with worked-example values
Measured values, not listing figures · update the sheet whenever any line changes, and retest the zone that line governs
Field Worked example Governs
Jar, batch, inside diameter at rim / middle / 1 cm above base Apothecary 500 gm, batch ___, ___ / ___ / ___ cm (measure; 9.3 cm assumed) All zones; a curved jar narrows or widens with depth
Fill weight and depth 500 g, about 8 cm deep (measure after pour) Bottom: hours above the stop line; label net weight
Wax, lot; oil, lot; load CSI 464, lot ___; Japanese Cherry Blossom, lot ___; 8% of total (40 g + 460 g) All zones; a change of any one means a retest

Top-third pass Pool at the glass by burn 2–3; flames about 2.5–5 cm; depth about 0.5–1 cm; photos ___ Wick size
Middle-third pass Flames steady and upright, no merging; depth not climbing session on session; halfway weight ___ g Spacing
Bottom-third pass At the labelled session cap: flames in range, upright, not near the glass; no heavy soot or carbon caps; depth recorded; burned to the stop line Session cap, stop line, fill
Measured burn rate and life 7.0 g an hour; about 62.9 h to a 1 cm stop line Label burn time
Label text Session cap ___ h; stop with ___ cm of wax left; burn within sight, away from draughts; trim before each burn Bottom (the customer's half of the spec)
Approved by, date, candles burned to the stop line ___, ___, ___ candles The sign-off

Two lines on that sheet are often missing in small workshops: measured spacing (wicks move during the pour; the target is not the result) and the label text. The session cap and stop line are as much a part of the candle as the wick: change them and the bottom zone has to be re-proven. Whether the glass gets hotter session by session as the candle goes down is tracked with the cumulative-heat trend chart, which feeds the bottom-third row.

Observing glass heat without touching it
CSI lists no non-contact thermometer. If you own one, record a reading at the same point and clock time each session; if not, record what you can see: flame-to-glass distance, a flame leaning towards the wall, soot on the glass, wax clinging high on one side. Never judge heat by touch. No particular glass temperature is "safe"; the 85°C on the Apothecary page is a pour limit, not a burn rating.

Fixing the bottom with the bottom's levers

Move the lever that governs the failing zone, and only that one, first.

Work down this list in order. Each step changes one thing, is judged on the bottom third only, and keeps what already passes at the top.

1
Was the failing session longer than your label?If the hot session ran five or six hours and your label says four, the candle may have passed as specified. Re-burn the lower third at the labelled cap before changing anything. Many "too hot at the bottom" results are long sessions.
2
Shorten the session capRe-burn the lower third of two candles from the same pour at a shorter cap (for example 3 h instead of 4 h). This does not shorten the candle's life; it limits how much heat builds in one session. If both pass, the fix is the label.
3
Raise the stop lineStop at about 1.5 cm instead of about 1 cm. On the worked example the extra 0.5 cm layer is 33.96 cm³; by the common 0.86–0.9 × water-weight rule of thumb that is about 29 g–31 g of wax, so take 30 g as the planning figure (weigh yours). Burn life falls from about 62.9 h to about 58.6 h, 4.3 hours fewer.
4
Use fill height to keep the hoursIf the stop line rises, adding about 30 g of fill (530 g) restores the burn hours, provided the headspace stays at the common 1–1.5 cm rule of thumb. On our example 30 g is about 0.48 cm more wax. Fill height does not cool the bottom; it buys back what the higher stop line costs.
5
Only then, spacingIf the bottom still fails, move the wicks about 5 mm closer together on a new pour and judge the middle and bottom zones. Expect a slower edge in burns 1–3 (each wick goes from 2.33 cm to 2.58 cm from the glass along the line), and re-check the top-third pass.
6
Last, wick sizeA size change re-tests every zone. On a pair of C1 there is no smaller sized, tabbed CSI wick; the options become a different count (a single Cotton Braided, described for candles "exceeding 8 cm") or another supplier's size, each a new bracket.
Argued against our own interest: steps 1–4 sell nothing but a roll of labels. Steps 5 and 6 need new pours and wicks. We would still rather you try the free steps first, and if your SKU is on a pair of C1, our range genuinely has no smaller sized, tabbed wick to offer.

Two cautions. First, a raised stop line and a session cap are promises your customer has to keep; write them plainly on the candle. Second, if every bottom lever fails, the jar may be the problem: some shapes trap heat near the base more than others, and that is the container-shape post's question. Final-third testing before approving a container is the final-third container post.

The retest rounds, costed

Re-burn before you re-pour. The bottom third of a candle you already have is the cheapest test you will run.

Round A, no new pour. Take two candles of the current build from the same pour. Burn them through the top two thirds on your normal schedule (or use candles already at the halfway weight), then burn the lower third at the shorter cap and stop at the higher line. Log every lower-third session: flame height and lean per wick, depth beside each wick, soot, carbon caps, flame-to-glass distance, weight before and after. If both pass, update the spec sheet's session cap and stop line, then the label. Cost: no new materials.

Round B, only if round A fails. A new pour of four candles: two at the current spacing (the control) and two with the wicks 5 mm closer together, both under the new cap and stop line, all burned to the stop line. One variable: spacing.

Costs exclude labour, freight, packaging and GST. Round B takes the candles' full life: at about 7.0 g an hour, roughly 58.6 hours each to a 1.5 cm stop line, so plan a few weeks of supervised sessions. A full-life calendar for planning is in the full-life calendar post; quicker screens of the bottom zone alone, labelled as screens, are the bottom-zone shortcut post.

How many complete burn tests a multi-wick SKU needs across a whole range of fragrances before production is the commercial test-count post; whether three wicks should all match is the identical-or-mixed post; and whether a stronger-smelling build is just burning more wax is the throw-per-gram post.

Buying for a multi-wick life-cycle spec

Five items, chosen on page statements, price and stock on 29 September 2026. The first is the one most bottom-zone fixes need; the others make the worked-example SKU and its retest. CSI publishes no wick-performance data and lists no non-contact thermometer.

Candle Care Stickers Roll
Two of the three bottom-zone levers are instructions: how long to burn at a time, and when to stop. They only work if they are on the candle. The page sells care stickers in rolls ("Size: 1 inch500 Stickers in a single roll"; "Size: 1.5 inch1000 Stickers in a single roll") and does not state the printed wording in the text we captured, so check the product images, or ask us on WhatsApp, before relying on a particular line; if it does not carry your session cap and stop line, print your own. Limitation: a label is a promise about how the candle will be used, not a fix; the candle must still pass its bottom zone at the session cap you print.

Eco Candle Wicks — Thin (C1)
The worked-example SKU runs a pair of C1. The page describes wicks of "natural fibers like cotton and paper" and states no size or jar range in the text we captured. The 100-pack (₹590.00, ₹5.90 each) is 50 two-wick candles: the production pack once the life-cycle spec is signed. Argued against our own interest: the per-wick price is the same in every pack, and if your SKU is already on C1, CSI has no smaller sized, tabbed wick to step down to, so the wick-size lever cannot fix your bottom zone with our range. The 10-pack is out of stock on 29 September 2026; a retest round needs the 20-pack.

Candle Making Weighing Scale
The spec sheet defines each zone by weight, not by eye: a 500 g fill has thirds of about 167 g, and the stop-line residue is weighed on the first full-life candle. The page describes a digital scale showing "grams or ounces" and states no capacity or resolution in the text we captured; check it holds your filled jar. Argued against our own interest: any kitchen scale that reads to 1 g and holds the jar does this job.

The CSI principle
Fix each depth with its own lever.
Wick size for the top, spacing for the middle, session cap, stop line and fill for the bottom. A multi-wick candle is approved when one spec sheet shows it passing at every depth, burned the way its label says.
"Smaller wicks fix the bottom by breaking the top. The label fixes the bottom and leaves the top alone."

Why trust this guide

CandleMakingSuppliesIndia sells the labels, wicks, jar, oil, wax and scale named here, and does not sell finished candles. This page still tells you that the first fixes cost nothing, that a kitchen scale will do, and that if your SKU is on a pair of C1 our range has no smaller sized, tabbed wick for you.

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 wherever it appears; every other size shown is in stock. Jar, oil, wax and label wording is quoted from the product pages; where a page is silent in the text we captured, we say so.

The zone-to-lever pairing, the spec-sheet template, the 0.35 cm wall, the 10 mm base, the 8 cm fill depth, the burn rate, stop-line residues and the retest rounds are our judgement or worked examples; late-burn heat is described as a common tendency; melt-pool depths, flame heights and headspace are commonly cited rules of thumb; CSI publishes no wick-performance data.

Why does my candle get hotter near the bottom of the jar?
Commonly because the glass above the pool absorbs and holds heat as the wax level falls, the pool sits closer to the base, and carbon builds on the wicks over many sessions. Multi-wick candles add their flames' heat to the same walls, so the effect is stronger.
Should I use smaller wicks if my candle overheats at the end?
Not first. Smaller wicks cool the bottom and the top, and the first burns commonly come back with a ring. Try the bottom-zone levers first: a shorter session cap, a higher stop line, then fill height; change wick size last and re-test the whole candle.
How much wax should be left when you stop burning a candle?
Many makers stop at about 1 cm of wax left; for a wide multi-wick candle that runs hot late, a higher stop line (about 1.5 cm) is a reasonable option to test. Put whatever you choose on the label.
How long should a multi-wick candle burn at one time?
There is no single figure; many labels say about 3–4 hours. Choose a session cap your candle passes in its lower third, test it at that cap, and print it on the candle.
What should a candle specification sheet include?
Measured jar dimensions, fill weight and depth, wax, oil and load with lot numbers, the wick build and lot, spacing measured after pouring, cure, pass criteria for the top, middle and bottom thirds, measured burn rate, the label text, and the sign-off.
Does adding more wax change how hot the bottom of the candle gets?
Not much: the bottom of the jar is where it is. More fill adds hours above the stop line, which is useful when you raise the stop line, as long as headspace stays at about 1–1.5 cm.
Before you change the wicks
Re-burn the lower third at a shorter session and a higher stop line, and write the result into a life-cycle spec.
Top third: wick size. Middle: spacing. Bottom: session cap, stop line, fill. Move the lever that governs the failing zone first, and approve only when a candle passes all three, burned the way its label says. Send us your spec sheet on WhatsApp.

About this guide: part of CSI's cluster on 10–12 cm jars and multi-wick problems (4261–4280). It covers why a multi-wick candle changes in its lower third, which lever governs which depth (wick size for the top, spacing for the middle, session cap, stop line and fill height for the bottom), a life-cycle spec sheet template, the order of fixes for a hot bottom, and costed retest rounds.

Non-price figures: load is a percentage of total candle weight (500 g at 8% = 40 g oil + 460 g wax; the standard 150 g candle at 8% = 12 g). The 500 g fill is a worked example within the Apothecary page's "~500 g - 700 g". The 0.35 cm wall, 10 mm base and 8 cm fill depth are assumptions; pool area = π r² on the inside radius; s = r is a labelled starting point. Ceilings are as the pages state (CSI 464 up to 10%, pour 80–90°C; Japanese Cherry Blossom 6–13% for candles, so 10% governs on CSI 464). The burn rate (7.0 g an hour), stop-line residues (60 g; 30 g more for 0.5 cm), burn-life hours and session counts are illustrative; the 0.86–0.9 wax-to-water ratio is a rule of thumb. Melt-pool depth (about 0.5–1 cm), flame height (about 2.5–5 cm) and headspace (about 1–1.5 cm) are commonly cited rules of thumb. Costs exclude labour, freight, packaging and GST. Diwali 8 November 2026 is a calendar fact.
