CSI Wick Lab · 7 cm Jars
A two-hour test measures the top of a candle. Pour the lowest third of your fill into the same jar and the flame starts where your candle overheated: a screen that can fail a wick in a session, never approve one.
50 g
shortcut pour that screens the bottom third of a 150 g candle · CSI live pricing, September 2026
Quick answers — read this first
Why does my 7 cm candle pass a two-hour test but overheat near the bottom? Because a two-hour test burns the top of the candle only (about 13 g, 9% of a 150 g candle, in our worked example). Near the bottom the flame has several centimetres of warm glass above it, a deeper pool and, in CSI's 150 g jars, a narrower base. A wick that is right for the top can be too big for the bottom.Can I test the bottom without burning a whole candle? You can screen it. Pour a bottom-zone shortcut candle: only the lowest third of the fill (50 g of a 150 g candle) in the same jar, on the same wick. Its first session puts the flame where your candle overheated.
What does the screen tell me? If the shortcut on your current wick overheats and one rung down does not, that smaller wick earns a full-life test. If both overheat, look at the jar, load or oil before the wick. A shortcut that passes never approves a wick.
What does it cost? Four shortcuts (two on C2, two on C1) at 8%: 16 g of oil, 184 g of wax, four jars and four wicks, ₹627.56 of materials.
The short answer
Why early looked right: two hours covers the top 9% of the candle, with little glass above the flame and cold wax below. The bottom zone is a different candle.
The screen: 50 g shortcut pours of the same jar, wax, oil and load: two on your wick, two one rung down. One or two sessions each, to about 1 cm left.
The rule (our judgement): shortcuts reproduce the overheat on your wick and not one rung down → full life on the smaller wick. Both overheat → jar, load or oil first. Neither → the screen can't see your problem; go straight to full life.
The honest limit: a shortcut can fail a wick quickly; only a full life can pass one.
In this guide
The same 150 g jar three times, at true scale. Left: session 1 of a full candle, the only part a two-hour test ever sees. Middle: that candle near the bottom, where it overheated, with about 52 mm of glass above a smaller pool. Right: a 50 g shortcut pour in the same jar, which starts life in that zone. Jar outer figures are the listing's; body height, base and wall are our assumptions; flames and pools are a worked example.

Straight answer
My 7 cm candle passes a two-hour test but overheats near the bottom. Why would a wick appear correct early in the burn and oversized later?
Because early and late are different candles in the same jar. In the first two hours the flame sits near the rim with almost no glass above it and a full jar of cold wax below to soak up heat; that is the only part of the candle a two-hour test measures. Near the bottom the flame sits deep inside the jar with several centimetres of glass above it that have been warming session after session, the pool commonly runs deeper, more wick is exposed, and CSI's 150 g jars narrow from a 7 cm rim to about a 6.5 cm base, so the same flame heats a smaller surface. A wick sized for the top can be oversized for the bottom: a tendency, and a common one. You do not have to burn a dozen hours to see it again. Pour bottom-zone shortcut candles: 50 g, the lowest third of your fill, in the same jar with the same wick, wax, oil and load. Their first session puts the flame straight into the zone that failed. Pour two on your current wick and two one rung down. If yours overheat and the smaller wick's do not, the smaller wick has earned a full-life test. If both overheat, look at the jar's taper, the load and the oil before the wick. A shortcut can fail a wick in an afternoon; it can never approve one.
One line: the two-hour test measured the top; a 50 g shortcut pour screens the bottom in a session; full life still decides.
For the four-candle screen: four Orange 150 g jars, 16 g of Fallen Leaves, 184 g of wax, two C2 and two C1 wicks, and a centering device pack: ₹627.56 of materials. Already have jars, wax and oil? Buy only the C1 20-pack (₹118.00).

Why the two-hour test looked right
Two hours is a fair test of the top of a candle, and silent about everything below it.
A two-hour test is not a bad test. It shows whether the wick lights cleanly, whether the pool starts spreading, whether the flame is steady and whether the first burn tunnels. Your candle passed all of that, and those are real passes. What it cannot show is the candle's future, for a simple reason: it burns so little of it. At a worked-example rate of 6.5 g an hour, two hours consumes about 13 g of a 150 g candle, the top 9%. The lowest third of the same candle (its last 50 g) is only reached after about 15.4 hours of burning, 4 sessions of 4 hours. A two-hour test has no information about that zone at all.
At the top, three things flatter the wick. The flame stands almost level with the rim, so there is little glass around it to hold heat. The whole candle below it is solid and cool, drawing heat away from the pool. And each test session starts from cold. None of those is true near the bottom.
Mistake: treating "passed two hours" as "passed". What happens: the wick is approved on the gentlest tenth of its life, and the first customer to burn a candle down finds the rest. Fix: call a two-hour test what it is, a start-up check, and plan the bottom from day one. The longer-burn version of this argument (two-hour versus long-cycle twins) is the passed-two-hours-failed-later post; this page gives you a faster screen for the part that failed.
What is different in the bottom third
Same wick, same wax, same oil. Different glass above, less wax below, and in this jar, less surface.
These are the changes candle makers commonly report as a container candle burns down. Each is a tendency, and together they explain why a wick can look correct early and oversized late:
Top zone vs bottom zone · a 150 g candle in CSI's 7 cm jar
Geometry declared; heights on a straight-sided approximation (0.88 × water, a rule-of-thumb midpoint); burn effects are tendencies, not CSI data
| Factor | Top of the candle | Bottom third | Commonly reported effect |
|---|---|---|---|
| Glass above the pool | About 7 mm on our assumed 72 mm body | About 4–5 cm | Warm glass holds heat around the flame; flames often grow |
| Wax below the pool | About 5.9 cm of solid wax | Under about 2.0 cm, warmed by earlier sessions | Less cold wax to absorb heat; pools often deepen |
| Pool surface (0.35 cm wall assumed) | 31.17 cm² at 6.3 cm inside | Toward 26.42 cm² at 5.8 cm, 15% less | The same flame heats a smaller surface |
| Wick | Fresh, trimmed, mostly buried | Near the tab, more exposed, carbon history | Carbon caps and taller flames are commonly reported |
| Base glass and tab | Far below | Close under the flame | The zone where test burns are stopped with about 1 cm left |
The taper deserves one more line. CSI's 150 g jar listings (the orange and clear versions alike) give a rim of about 7 cm and a base of about 6.5 cm. That half-centimetre is invisible on the shelf and about 15% of pool area by the base. If the taper is the main culprit, choosing the wick for the narrow part is its own decision, covered in the narrowing-jar retest; the shortcut screen below helps you see whether that is where your problem lives.
Measure your jar at three heights
Rim, middle and about 1 cm above the base, inside to inside. The listing figures are outer and approximate. If your base is noticeably narrower than your rim, write both down: every later decision uses them. How to measure is in the cluster hub.The bottom-zone shortcut candle
Pour only the part that failed. The flame starts where your candle ended.
A bottom-zone shortcut candle is a shallow pour of the lowest third of your fill weight into the same jar, on the same wick, in the same wax and oil at the same load. For a 150 g candle that is 50 g: 4 g of oil and 46 g of wax at 8% of total weight, about 2.0 cm deep on our approximation. When you light it, the flame is immediately at the height where your full candle overheated, with the same jar walls around it. What took a full candle about 15.4 hours to reach, the shortcut reaches in its first minute.
1
Same everything except depthSame jar listing and batch, same wick type from the same pack, same wax bag, same oil at the same load, same pour temperature. The only change is 50 g instead of 150 g.
2
Weigh the pourTare each jar with its wick in. Pour exactly 50 g. The shallow layer is easy to over- or under-fill by eye.
3
Centre and hold the wickA pre-tabbed wick stands tall in 2 cm of wax and leans while it sets. Hold each one with a centering device or two sticks until the wax is firm.
4
Cure like the real candleSame cure as your full candles, same shelf. Fallen Leaves' page gives 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 wait about a week.
5
Trim, then burn to the stopTrim to about 5–6 mm. Burn in still air until about 1 cm of wax is left, which on our approximation is about 25 g; weigh to find it. At a worked-example 7 g an hour, the 25 g above that stop is one session of about 3.6 hours, or two shorter ones.
6
Log what failed in the full candleTrimmed flame height at 1 h and at the end, pool depth near the wall, carbon on the wick, soot on the glass, and whether the flame leans toward a wall. Watch the glass; never touch it.
A shortcut saves wax and oil as well as time. Four shortcut candles are 200 g of candle against 600 g for four full ones; oil and wax for the four shortcuts cost ₹337.76 less, though the jars cost the same (₹596.88 against ₹934.64 for oil, wax and jars). The real saving is days: the bottom zone in a session instead of a week of evenings.
The four-candle screen and how to read it
Two cells, two candles each. One question: does the smaller wick deserve a full life?
Pour four shortcuts on the same day: two on the wick that overheated (C2 in our worked example) and two on one rung down (C1). The first pair checks that the shortcut reproduces your problem; the second asks whether the smaller wick avoids it. Decide your lines before you light: many makers use about 2.5–5 cm as a practical flame range and about 0.5–1 cm as a pool-depth target (commonly cited rules of thumb, not CSI data).
Bill of materials · four-candle shortcut screen · worked example
Fallen Leaves at 8% · CSI 464 · Orange Glass Jar with Golden Lid (150 gram) · Eco C2 and C1 · CSI live pricing, 29 September 2026
| Cell | Candles | Oil | Wax | Wicks |
|---|---|---|---|---|
| Current wick (C2), 50 g shortcut | 2 | 8 g | 92 g | 2 × C2 |
| One rung down (C1), 50 g shortcut | 2 | 8 g | 92 g | 2 × C1 (20-pack; the 10-pack is out of stock) |
| Screen | 4 jars | 16 g | 184 g | 4 wicks |
Materials consumed: ₹627.56, of which four jars are most (₹428.00); without jars it is ₹199.56. A C2 shortcut candle costs ₹158.66 against ₹243.10 for a full 150 g one. These are worked examples and exclude labour, freight, packaging and GST.
Reading the screen (our judgement, labelled)
"Overheats" = on both shortcuts of a cell: trimmed flame past your line, or pool past about 1 cm, or soot, carbon cap or a flame leaning to the glass
| C2 shortcuts | C1 shortcuts | What it points to | Next step |
|---|---|---|---|
| Overheat | Stay inside your lines | The smaller wick handles the bottom zone | Full life on C1, three candles, watching the top for tunnelling (the full-life calendar) |
| Overheat | Overheat | Wick size alone may not be the lever | Check the taper (narrowing-jar retest), the load and the oil; don't run a full life on C1 yet |
| Stay inside | Stay inside | The shortcut can't reproduce your problem: your failure needs the heat history of a full candle | Skip screens for this jar; go straight to full-life candles on C2 and C1 |
| One of two overheats | — | Noise: centring, trim or a draught | Pour two more of that cell |
If C1 passes the screen and then tunnels at the top in the full candle, your answer sits between C1 and C2, and CSI has no sized, tabbed wick in between. Say so in your notes, ask us, and weigh the options in the narrowing-jar post. Whether C1 and C2 are enough to call a bracket closed is the adjacent-sizes post.
Argued against our own interest: if your screen comes back "both overheat", the fix is probably not a purchase from us. It may be a lower load, a straighter jar, a different oil or a shorter recommended session. We would rather you found that out with four 50 g candles than with a pack of wicks you didn't need.
What a shortcut can't tell you
A screen is a quick "no". It is never a "yes".
The shortcut copies the geometry of the bottom zone: the glass above the flame, the jar's narrower base, the tab close underneath. It does not copy the history. A full candle arrives at its last third after hours of earlier burning: the glass has been heated and cooled several times, the wick has been trimmed and has carried carbon, top notes have been burning off for sessions, and the remaining wax has been through repeated melting. Any of those can make the real bottom behave a little hotter or a little differently from a fresh shallow pour. That is why the rule is lopsided:
What each shortcut result is worth
Our judgement, stated plainly
| Result | What it proves | What it doesn't |
|---|---|---|
| Shortcut overheats | Strong evidence the wick is too big for the bottom zone: even without the history, it runs past your line | How much smaller the right wick is |
| Shortcut stays inside your lines | That the wick is worth a full-life test | That the full candle's bottom will pass; the history may still push it over |
| Shortcut on your current wick doesn't reproduce your full candle's overheat | That your problem depends on history, not geometry alone | Anything about a smaller wick; go to full life |
Mistake: approving a wick for production because its shortcut burned beautifully. Why it fails: the top two-thirds were never burned, so neither tunnelling at the top nor accumulated heat at the bottom has been tested. Fix: shortcuts decide which wick goes to full life, not which wick goes to market. The full-life test is a calendar of about two weeks.
Safety is the same as for any late-life burn. Shortcut candles sit close to the glass base from the first minute: burn within sight, in still air, and stop with about 1 cm left. Judge the glass by what you can see (flame distance to the wall, soot, a lean) or with a non-contact thermometer, which CSI does not list. Never touch the glass to judge heat, and never extend the jar page's "Safe for hot-pour up to 85°C" into a burn rating: it describes pouring.
What to buy, and what to skip
Five items for the screen and the full-life candles that may follow, chosen on page statements, price and stock on 29 September 2026. CSI publishes no wick-performance data, so nothing here is ranked on burn results. Oil candle counts use 4 g per 50 g shortcut and 12 g per 150 g candle at 8%.

jar · the 7 cm, 150 g listing in the worked example
Orange Glass Jar with Golden Lid (150 gram)
The page states "Height (with lid): Approx. 8 cm", "Diameter (outer rim): Approx. 7 cm", "Base diameter: Approx. 6.5 cm", "Fill capacity: ~150 gm" and "Safe for hot-pour up to 85°C", which is a pour limit, not a burn rating. The narrower base is the point: the bottom-zone pool is about 15% smaller than the rim pool on our assumed wall. The handle still carries old "deliveries starting 5th Dec" text although the listing is in stock on 29 September 2026; confirm dispatch on WhatsApp. Argued against our own interest: coloured glass hides the wax line from the side; if your product jar is not orange, screen in the jar you sell. The Clear 150 g jar lists the same rim and base and costs ₹94.40 a jar, ₹12.60 less.
| Pack | Price | Per unit | What it covers here |

tool · shallow pours need a steady wick
Wick Centering Device (Pack of 5)
A 50 g pour is about 2.0 cm of wax: the pre-tabbed wick stands mostly out of it and leans while the wax sets. A wick that sets 2–3 mm off-centre sends the bottom-zone flame toward one wall, which is the very thing you are screening for. The page describes a wooden bar, "Length 4.4" (11,4 cm)", one "Hole Dia 0,15" (4mm)", for openings "less than 4"". Five in a pack hold all four shortcut wicks at once. Argued against our own interest: two ice-cream sticks and a clip do the same job.
| Pack | Price | Per unit | What it covers here |
|---|---|---|---|
| Pack of 5 | ₹118.00 | ₹23.60 | holds all four shortcut wicks at once while the shallow pours set |
₹23.60 a holder, reusable. Buy 5 — ₹118.00

wick · the rung under suspicion and the rung below
Eco Candle Wicks — Thick (C2) and Thin (C1)
In the worked example the candle overheats low down on C2, so the screen compares C2 with one rung down, C1. The page states no size or jar range in the text we captured. Stock on 29 September 2026: the C1 10-pack is out of stock; the 20-pack and every C2 pack are in. Honest limit: no sized, tabbed wick sits between C1 and C2. If C2 overheats at the bottom and C1 tunnels at the top, CSI has nothing in between; see the narrowing-jar retest linked above before you look elsewhere.
| Pack | Price | Per unit | What it covers here |
|---|---|---|---|
| Thick (C2) / 10 | ₹94.40 | ₹9.44 | the wick that overheats in the worked example: 2 shortcuts, 8 spare |
| Thin (C1) / 10 | ₹59.00 — Out of stock | ₹5.90 | Out of stock on 29 September 2026 |
| Thin (C1) / 20 | ₹118.00 | ₹5.90 | 2 shortcuts, then 3 full-life candles if C1 screens well; 15 spare |
Screen wicks: 2 × C2 + 2 × C1 = ₹30.68. Buy C1 20 — ₹118.00

fragrance oil · fruity spicy · the worked example's oil
Fallen Leaves
The page lists "Top Notes: Crisp Apple, Bergamot, Spicy Cinnamon", "Middle Notes: Dried Leaves, Rose, Jasmine", "Base Notes: Amber, Musk, Vanilla" and states "Recommended fragrance load is 6-10% for candles"; 8% is mid-range and inside CSI 464's 10%. It lists vanilla among its base notes but gives no vanillin figure or cure time in the text we captured. Every size is in stock on 29 September 2026. Argued against our own interest: the 50 g and 100 g are both ₹4.72 a gram; the screen alone uses 16 g, so the 50 g is enough unless you go on to full life (52 g in all), when the 100 g covers both.
| Size | Price | Per gram | 50 g shortcuts at 8% | 150 g candles at 8% |
|---|---|---|---|---|
| 15 g | ₹94.40 | ₹6.29 | 3 | 1 |

wax · the soy in the worked example
Luxury Soy Wax CSI 464 (Flakes Form) For Container Candles
The page states "Fragrance Load Up to 10%" and "Pour Temperature 80°C – 90°C"; with the jar's "Safe for hot-pour up to 85°C", pour at 80–85°C. A shallow 50 g pour cools faster than a full one, so pour all four shortcuts together and let them set undisturbed. Use the wax your product uses: wick results do not transfer between waxes. Limitation: the 500 g bag covers the screen but not the full-life candles after it.
| Pack | Price | Per unit | What it covers here |
|---|---|---|---|
| 500 g | ₹260.00 | ₹0.52 per g | the screen (184 g) but not the full-life candles after it |
| 1 kg | ₹507.40 | ₹0.51 per g | screen + full life (598 g), 402 g left |
| 10 kg | ₹5,074.00 | ₹0.51 per g | production; flat per gram from 1 kg |
Screen wax: 184 g = ₹93.36. Buy 1 kg — ₹507.40
What not to buy: Cotton Braided Wicks for this jar: its page describes it for candles "exceeding 8 cm", and a candle that overheats at the bottom needs less heat, not more. The Steel Wick Holder (₹250.00 for 5) for single-wick shortcuts: the ₹118.00 centering device does the job. A 20-pack of jars for a screen: the same price per jar. Fallen Leaves 500 g before the wick is settled: cheaper per gram (₹4.25), but a screen and a full life use 52 g.
Diwali is 8 November 2026, 40 days from 29 September 2026. A shortcut screen poured this week and cured about a week gives you its answer by mid-October; the full-life candles for the winner need about two weeks after that.

The CSI principle
Screen the bottom early; approve it only at the bottom.
A two-hour pass describes the top of a candle. A 50 g shortcut pour shows the bottom zone in a session and can fail a wick fast. Only a full life, burned to about 1 cm left, can pass one.
"Your two-hour test was right about the first two hours. The bottom of the jar never got a vote."

Why trust this guide
CandleMakingSuppliesIndia sells the jars, wicks, oil, wax and centering devices named here, and does not sell finished candles. This page still points out that ice-cream sticks centre a wick as well as our device, that the clear version of the jar is cheaper, and that a "both overheat" screen usually means the fix is not something we sell.
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 flagged wherever it appears; every other size shown is in stock. Jar dimensions and heat wording, load ranges and notes are quoted from the product pages; where a page is silent in the text we captured, we say so.
The shortcut method, its decision rule and the lopsided "fail fast, never pass" reading are our judgement. Body height, base thickness and wall are assumptions; heights use a straight-sided approximation with a rule-of-thumb wax factor; burn rates, flames and pools are a worked example; flame and depth ranges are commonly cited rules of thumb.

Frequently asked questions
Why does my candle burn fine at first and overheat at the bottom?
Near the bottom the flame has warm glass above it, a deeper pool and less cold wax below, and many jars narrow toward the base. A wick sized for the top can be too big for the bottom. A two-hour test only burns the top of the candle.
Is a two-hour burn test enough for a candle wick?
It is a start-up check, not an approval. In a 150 g candle two hours burns roughly the top tenth. Screen the bottom with a shallow shortcut pour if you like, then burn full candles to about 1 cm left before approving a wick.
What is a bottom-zone shortcut candle?
A shallow pour of the lowest third of your fill weight (50 g of a 150 g candle) in the same jar, on the same wick, wax, oil and load. Its first session puts the flame where your full candle's last sessions would be, so bottom-zone overheating shows up in hours.
Can a shallow test candle replace a full burn test?
No. It copies the bottom zone's geometry but not the heat and carbon history of a candle burned down over many sessions, and it never tests the top. If it overheats, that is strong evidence; if it passes, run full candles.
Should I choose the wick for the narrowest part of the jar?
Only if the top still passes with it. In a jar that narrows toward the base, a smaller wick can fix the bottom but tunnel at the top. Screen the bottom with shortcut pours, then run full candles on the candidate wick.
Why does my candle flame get bigger when the wax is low?
Commonly because the glass above the pool warms and holds heat, the pool gets deeper and more wick is exposed. If the flame goes past about 5 cm, soots or leans toward the glass low down, the wick is likely too big for that zone.
Before you change the wick for the whole candle
Screen the bottom with four 50 g shortcut pours: ₹627.56 in materials.
Two shortcuts on your current wick, two one rung down, same jar, wax, oil and load. Burn to about 1 cm left and log flame, pool depth and soot. If only the smaller wick stays inside your lines, give it a full-life test. Send us your results on WhatsApp.

About this guide: part of CSI's cluster on 6–7 cm jars with a single wick (4201–4220). It owns bottom-zone shortcut candles (shallow pours of the lowest third of the fill weight in the same jar) as a screen for late-burn overheating, the four-candle screen and its reading, why a two-hour test looks right early, and the limits of a shortcut.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 — Autumn, Bamboo Wick Holder, Black Matte Glass Jar, Luxury Soy Wax CSI 464 (Flakes Form) For Container Candles, White Matte Glass Jar, White Matte Votive Jar 70 gram.

Non-price figures: load is a percentage of total candle weight (150 g at 8% = 12 g oil + 138 g wax; the 50 g shortcut = 4 g + 46 g). Jar figures (with-lid height about 8 cm, outer rim about 7 cm, base about 6.5 cm, "Safe for hot-pour up to 85°C") are page wording; the 72 mm body, 6 mm base and 0.35 cm wall are assumptions. Wax heights use a straight-sided approximation at the mean inside diameter and 0.88 times the water weight (a rule-of-thumb midpoint). Burn rates, flame heights and pool depths are a worked example. Flame range (about 2.5–5 cm), pool depth (about 0.5–1 cm), the stop at about 1 cm and the hour-per-2.5 cm rule are commonly cited rules of thumb or practice. The screen's decision rule is editorial judgement. Costs exclude labour, freight, packaging and GST. Diwali 8 November 2026 is a calendar fact.
