CSI Wick Lab · 12 cm Jars
Three wicks placed by eye in a 12 cm jar are usually a few millimetres out, and the glass notices before you do. Draw one circle, step three marks with a compass, and check six distances before the wax sets.
30.00 mm
starting circumradius in a jar 12.0 cm inside: marks 51.96 mm apart, 30.00 mm from the glass · CSI live pricing, September 2026
Quick answers — read this first
How do I position three wicks evenly in a 12 cm jar? Draw a paper template from the jar's measured inside: a circle for the wall, a second circle at half the inside radius, and three marks 120° apart on it. For a jar 12.0 cm inside that is a 30.00 mm circle with marks 51.96 mm apart, each 30.00 mm from the glass. Fix each tab on its mark with a sticker and hold the tops in a pierced card while the wax sets.

Why does even placement protect the glass? Because the glass near a wick heats with that wick's distance from it. Place one wick 5 mm too far out and its wall clearance drops from 30.00 to 25 mm, 16.7% less, so one side of the jar works harder than the others.

How do I know it worked? Measure six distances after the pour: three wick-to-wick and three wick-to-wall, each within ±2 mm of target (our tolerance). Correct any wick while the wax is still liquid.

Does CSI sell a holder that does this? No. The Steel Wick Holder's holes sit in a line and it fits jars up to 9 cm; we list no 12 cm jar either. A card, a compass and wick stickers do the job.
The short answer
The template: inside wall circle, centre, a circle of ρ = r/2, three marks stepped with a compass set to ρ√3; 12.0 cm inside → ρ 30.00 mm, marks 51.96 mm apart, 30.00 mm to the wall.
The fixing: tabs pressed onto the marks through windows in a template disc, large stickers under each tab, wick tops held in a needle-pierced rim card at the same three points.
The re-check: six distances after pouring, each within ±2 mm; fix while liquid, re-pour if set.
The honest limits: no CSI holder sets three wicks in a triangle; no CSI jar is listed at 12 cm; ρ = r/2 is a starting point, not a final layout.

Three marks on a circle of half the inside radius, 120° apart; the small rings around each mark are the ±2 mm tolerance. The compass chord that steps the marks, 51.96 mm, is also the wick-to-wick distance you measure after pouring. The panel gives the 11.3 cm inside figures for a jar whose 12 cm is the outside.

Straight answer
I'm using a 12 cm jar with three wicks. How do I position them evenly enough to create a balanced melt pool without overheating the glass?
Use a template drawn from the jar's measured inside, not your eye. Measure the inside diameter at the height of the wax surface; if your 12 cm is the outside figure, an assumed 0.35 cm wall makes it 11.3 cm inside. On card, draw a circle of that diameter and mark its centre. Draw a second circle at half the inside radius (ρ = r/2, our labelled starting point): 30.00 mm for a jar 12.0 cm inside. Set a compass to ρ√3 (51.96 mm) and step three marks round the small circle; they land 120° apart, each 30.00 mm from the glass. Cut a small window at each mark, lay the disc in the empty jar and press each tab, on a sticker, onto its mark. Hold the three wick tops in a rim card pierced at the same three points. After pouring, while the wax is still liquid, measure the three wick-to-wick and three wick-to-wall distances and nudge any wick that is more than 2 mm out. Even clearance is what keeps one side of the glass from working harder than the others. Whether ρ = r/2 is the right circumradius for your candle, or whether the wicks are the right size, are separate tests; this one makes sure the layout you are testing is the layout you poured.
One line: measure the inside, draw a circle at half the radius, step three marks with a compass set to ρ√3, fix the tabs on them, and check six distances before the wax sets.
Placement costs card and stickers, not wicks: a sheet of 40 large stickers (₹249.00) covers thirteen three-wick candles; the needle (₹472.00) is optional. No new wick size is needed to place the ones you have.

Why "evenly" is a wall-clearance question

An uneven triangle doesn't just melt unevenly. It heats one side of the glass more than the others.

In a round jar with three identical wicks, each wick melts its own share of the pool and warms the glass nearest to it. If all three sit the same distance from the centre and 120° apart, every wick has the same wall clearance and the same neighbours, and the pool grows as three equal scallops that meet the glass together. Move one wick outwards and its scallop reaches the glass first, while the glass on that side receives a flame closer than the other two. Move one inwards and its sector lags, leaving wax on that side while the centre runs warmer. These are tendencies of how flames heat wax and glass, not measured CSI data, but they explain why an "about right" triangle often gives a lopsided pool.

The numbers are small, which is why the eye misses them. At ρ = 30.00 mm in a 12.0 cm jar, every wick is 30.00 mm from the glass. A 2 mm error outwards cuts that by 6.7%; a 5 mm error, easy to make by eye in a jar 12 cm across, cuts it by 16.7%, to 25 mm. The glass sees the difference long before you do. Judge it by flame-to-glass distance, any blackening and how the glass looks, never by touch; CSI lists no non-contact thermometer, and this post sets no glass-temperature limit.

Mistake: placing the first wick in the centre-ish and "balancing" the other two around it by eye. Why it fails: three judgements, each a few millimetres out, compound; the triangle ends up shifted towards one side and slightly twisted. Fix: all three positions come from one drawn circle and one compass setting, so their errors don't add.

The template for a 12 cm jar

Draw for the jar you measured, not the number on the listing.

CSI lists no jar at 12 cm by any stated diameter, so this is your jar and your measurement. The pool area at 12.0 cm inside is 113.10 cm², 66% more than the 9.3 cm inside of CSI's 10 cm Apothecary listing, and three wicks each serve 37.70 cm². If you need a wider jar, ask us; we would rather say "not listed" than guess. Measure the inside at the rim, at the expected wax surface and near the base: the template belongs at the base, where the tabs sit, but the wicks burn at the surface, so a jar that tapers needs a note of both. The external-diameter post covers why the outside figure misleads.

Template figures · whichever 12 cm you have
ρ = r/2 starting point · wick to wick ρ√3 · wick to wall r − ρ · declared in the calculations
Inside diameter Inside radius r Pool area Circumradius ρ Wick to wick Wick to wall
12.0 cm (12 cm measured inside) 60 mm 113.10 cm² 30.00 mm 51.96 mm 30.00 mm
11.3 cm (12 cm outside, 0.35 cm wall assumed) 56.5 mm 100.29 cm² 28.25 mm 48.93 mm 28.25 mm

The two rows look close, but drawing the 12.0 cm template in a jar that is really 11.3 cm inside puts every wick at 26.50 mm from the glass instead of 28.25 mm, 6% less clearance, before any placement error. That is why the first step is a ruler inside the jar. Why ρ = r/2 as the start: for three wicks in a triangle it gives the shortest distance from any wick to the farthest wall point (here 51.96 mm, the same as the wick-to-wick distance). It is a sensible first layout, and the place to start the circumradius ladder in the triangle-spacing post if the centre later runs hot.

Clear glass shortcut
For a clear jar with a flat base, draw the template on paper and slide it under the jar. Look straight down through the glass and set each tab over its mark. Thick bases bend the view slightly, so look from directly above each mark, not at an angle. For tinted, frosted or opaque jars, use the in-jar disc with windows.

Drawing the template in ten minutes

A compass, a ruler and one card. The compass does the accuracy for you.
1
Measure the insideSteel ruler across the base inside the jar, at two angles at right angles to each other. If they differ by more than a millimetre or two, the jar is not quite round: use the smaller figure and note it.
2
Cut the discA card disc 118 mm across for a 12.0 cm jar (inside diameter less about 2 mm, so it lies flat). Mark the centre where two diameters cross.
3
Draw the wick circleCompass set to ρ = r/2: 30.00 mm for 12.0 cm inside, 28.25 mm for 11.3 cm. Draw the circle from the centre.
4
Step the marksReset the compass to ρ√3, 51.96 mm (or 48.93 mm). From any point on the small circle, swing an arc to cut it; from that cut, swing again. Three cuts close back on the start: three marks 120° apart. If the third arc misses the start by more than 1 mm, re-measure the compass.
5
Cut the windowsAt each mark, cut a small square window a little larger than a wick tab, centred on the mark. The tab will sit in the window; the disc lifts out over the wicks.
6
Make the rim cardA second card, larger than the jar's outer rim, with the same centre, circle and marks transferred by laying the disc on top. Pierce each mark with a needle or awl. Write the jar's inside figure and ρ on both cards and keep them for the next batch.
Mistake: stepping the marks with a protractor and a pencil held loosely. Why it fails: a 2° error at a 30.00 mm radius moves a mark about a millimetre sideways, and three loose marks rarely close evenly. Fix: the compass chord: if three equal arcs close on the starting point, the marks are 120° apart by construction.

Fixing three tabs on three marks

The template is only as good as the sticker that keeps the tab where it was put.

Clean the jar base, warm the jar slightly if your workroom is cold (our judgement; adhesives grip better on a warm, dry surface), and lay the template disc flat inside. Put a sticker on each tab, peel the backing, and press the tab down through its window, centred on the mark. Press firmly for a few seconds each. Lift the disc out over the wicks. Now thread the wick tops through the rim card's three holes and rest the card on the rim, rotated until each wick stands vertical. The wick at 12 o'clock on the disc must be at 12 o'clock on the rim card: mark a matching tick on both cards and on the jar.

Why not CSI's holders? We would rather be plain. The Steel Wick Holder page says its "3-hole layout fits single, double, or triple wick setups" and fits "up to 9 cm wide": the holes are in a line, and it is shorter than your jar is wide. The Wick Centering Device has one hole and is described for openings "less than 4"". The Wick Setting Tool holds wicks along one magnetic bar, and its page tells you to "Gently nudge the wick to the center", a single-wick instruction. None sets a triangle; the rim card does.

Argued against our own interest: you don't need the needle, and you may not need the large stickers. A pencil point makes acceptable holes in a rim card, and our 10 mm stickers (₹100.00 for 40) hold C1 and C2 tabs. Buy the larger stickers if the small ones won't sit square in your windows, and the needle if you make three-wick candles often enough to want neat, repeatable holes.

Re-checking after the pour

Six measurements, taken while you can still do something about them.

Pour from one melt at the low end of CSI 464's stated 80–90°C range unless your jar maker states otherwise. Wicks drift as wax is poured and as it starts to cool, and a rim card hole that is a little loose lets a wick lean. So measure twice. First, while the wax is still liquid (a minute or two after pouring): with a steel ruler resting across the rim, check the three wick-to-wick distances at the surface; nudge any wick back using the rim card. Second, once the wax has set: measure all six distances at the surface, three wick-to-wick (51.96 mm target) and three wick-to-wall (30.00 mm target), and write them on the base label.

Reading the six post-pour distances
Targets for 12.0 cm inside: wick to wick 51.96 mm, wick to wall 30.00 mm · ±2 mm tolerance is our judgement, labelled
What you measure What it means What to do
All six distances within ±2 mm of target Even placement Keep it; this candle tests the layout, not your hand
One wick-to-wall short by 3–5 mm, its two wick-to-wick distances off by about the same One wick drifted outwards Nudge it back while the wax is liquid; if set, mark the candle "placement fail" and re-pour
All three wick-to-wall distances short by the same amount The template is too big for this jar (or the jar is narrower than measured) Redraw from the inside measured at the surface height
Wick-to-wick distances unequal, wick-to-wall roughly equal Marks not at 120° (the triangle is twisted, not shifted) Re-step the chord; check the template before the next pour
A wick leans: surface position differs from tab position by more than 2 mm Top not held, or the rim card hole is loose Smaller hole in the rim card; hold until the wax is opaque

A candle that fails the tolerance is still useful: burn it as a teaching candle and watch whether the drifted wick's side behaves as the geometry predicts. But don't let it into a comparison. The same rule applies to a two-wick candle in a 10 cm jar, where a level-and-position audit is the drowning-wick post; with three wicks there are simply more distances to check.

Does the template fix your pool? A four-candle check

If your three-wick candle melts unevenly, find out whether placement was the cause before you change anything else.

Pour four candles from one melt: two placed with the template and re-checked within ±2 mm, and two placed by eye the way you placed the candle that disappointed you. Everything else is identical: Citrus Lemon at 8% in CSI 464, an 800 g fill (64 g oil, 736 g wax) in four jars from one batch, 3 × C2 in each. Cure them together (the oil page says "Cure soy wax candles for 48-72 hours before burn testing"; about a week is common practice). Burn one at a time or well apart, in still air, within sight, for 4-hour sessions; the rough hour-per-2.5 cm rule suggests about 4.8 hours for 12.0 cm (4.5 for 11.3 cm), so burn 1 may not reach the glass, and you judge on burns 2 and 3. At the end of each session log, per wick: how far its scallop is from the glass, its flame height, how close its flame sits to the glass, and any soot on that side.

Reading the four-candle check · burns 2 and 3
Templated pair against by-eye pair · same oil, load, wax, wicks and jar batch · our judgement, labelled
What you see What it means Decision Purchase
Templated candles reach the glass evenly, by-eye candles don't Placement was your uneven pool Use the template on every candle; no new wicks Nothing beyond stickers
Both sets leave wax in the same place, which follows the room when you turn the jar Airflow, not placement Run the ceiling-fan test before changing anything Nothing
Both sets are even, but the glass looks hot or flames sit close to it Placement is fine; ρ or wick size is the question Test circumradius (the ρ ladder) or size next Nothing yet
Templated candles are even but run deep in the centre Even, but tight The ρ ladder: same wicks, wider triangle Nothing yet
Templated candles still uneven in one sector, and it follows one wick One wick or its setup Re-measure that wick; check trim and lean Nothing

If the room is the cause, the ceiling-fan post separates airflow from wick faults. If the glass is the concern once placement is even, the per-session trend chart in the cumulative-heat post shows whether heat is building burn over burn. And if placement is even but you are tempted to use one larger wick and two smaller ones to "balance" the pool, read the identical-or-mixed post first; in a round jar, symmetry usually argues identical. Every multi-wick candle still needs its full life to about 1 cm left before approval; the full-depth post explains how far down to test.

Argued against our own interest: if you have already measured your existing candle and its wicks are out by more than 2 mm, you don't need the by-eye control. Pour two templated candles only (128 g of oil, 1,472 g of wax, ₹1,958.20 from nothing) and compare them with your old notes. The control is for makers who aren't sure placement was the problem.

accessory · the tab stays on its mark
Large Candle Wick Stickers
Three tabs, each pressed onto a pencil mark through a window in the template; a sticker that shifts 2 mm moves a wick 6.7% closer to or further from the glass. The listing calls them "20mm Candle Wick Round Stickers", says "the 10mm diameter ensures a secure fit" and has "x 2mm" in the title, so check the size on arrival; a wider sticker is easier to centre under a tab inside a narrow window. Argued against our own interest: the 10 mm sheet of 40 is ₹149.00 cheaper and holds C1 and C2 tabs; buy the large ones if the small ones won't sit square through your template window.

Premium Candle Wicking Needle
The rim card holds the three wick tops at the same 120° marks while the wax sets. A needle pierces three small, clean holes, so each wick passes snugly and can't wander in a ragged slot. The listing promises "flawless wicking" and states nothing about jars or sizes in the text we captured; one reviewer uses it with a mould. Argued against our own interest: a sharp pencil or an awl makes acceptable holes, and the needle costs ₹223.00 more than the stickers that actually fix your tabs. It earns its place if you make many three-wick candles or also wick moulds.

A light citrus suits a placement check: the question is where the pool reaches, and a lighter oil adds less wick behaviour of its own (a tendency). The listing states "candles (6-10%)" and "Cure soy wax candles for 48-72 hours before burn testing - citrus fragrances benefit from full cure time"; notes: "zesty lemon and lime top notes, bright grapefruit and orange heart, and a tangy mandarin finish". Argued against our own interest: for four 800 g candles (256 g) three 100 g bottles (₹900.00) cost ₹520.00 less than the 500 g and leave 44 g; the 500 g is cheaper per gram (₹2.84 against ₹3.00).

The page states "Fragrance Load Up to 10%" and "Pour Temperature 80°C – 90°C". Your 12 cm jar is not a CSI listing, so no CSI page gives it a heat figure: follow your jar maker, pre-warm clean jars and pour at the low end of the range (our judgement).

The CSI principle
Place three wicks with geometry, then prove it with a ruler.
One measured circle, one compass setting, three marks; tabs fixed on them, tops held at the same points; six distances checked before the wax sets. Even clearance is what keeps the glass working evenly.
"Three wicks placed by eye are three guesses. Three wicks placed from one circle are one decision you can check."

This page still tells you that none of our holders sets a triangle, that we list no 12 cm jar, that a pencil can replace the needle, that our cheaper stickers may do, and that you may not need the control candles at all.

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 where it appears; every other size shown is in stock. Oil, wick, wax, sticker, needle and holder wording is quoted from the product pages; where a page is silent in the text we captured, we say so.

The template geometry is exact for the stated assumptions; the 0.35 cm wall, the ρ = r/2 start, the 800 g fill, the ±2 mm tolerance, the 2 mm disc allowance and the decision lines are our judgement or worked examples. The hour-per-2.5 cm rule and the 0.86–0.9 wax factor are commonly cited rules of thumb, not CSI data; CSI publishes no wick-performance data.

Frequently asked questions

How do I place three wicks evenly in a candle jar?
Draw a template: a circle for the jar's inside, a smaller circle at half the inside radius, and three marks stepped round it with a compass set to that radius times 1.73. Fix each wick tab on a mark with a sticker and hold the tops in a card pierced at the same points.
Where should three wicks go in a 12 cm candle?
As a starting point for testing, on a circle half the inside radius from the centre, 120° apart. In a jar 12.0 cm inside that is 30 mm from the centre, about 52 mm apart and 30 mm from the glass; measure your jar's inside first.
How do I mark 120 degrees without a protractor?
Set a compass to the circle's radius times 1.73 (the chord for 120°) and step it round the circle three times; the third arc should land back on the start. Or step the radius itself six times round and use every second mark.
Why does one side of my three-wick candle get hotter?
Often one wick is closer to the glass than the others, by a few millimetres you can't see. Measure each wick-to-wall distance at the surface. If they are even, check airflow by turning the jar between sessions. Judge glass by eye, never by touch.
Can I use a wick holder for three wicks in a wide jar?
Not one from CSI for a triangle: the Steel Wick Holder has three holes in a line and fits jars up to 9 cm. A card pierced at the three template marks holds the wick tops upright while the wax sets.
How accurate does three-wick placement need to be?
We work to ±2 mm on each wick-to-wick and wick-to-wall distance (our judgement). At 30 mm from the glass, a 5 mm error cuts one wick's clearance by about a sixth, enough to unbalance the pool and the glass.
Before you blame the wicks
Draw one circle, step three marks, and check six distances.
For a jar 12.0 cm inside: marks on a 30.00 mm circle, 51.96 mm apart, 30.00 mm from the glass, each within ±2 mm after the pour. If your pool is still uneven, a four-candle check (₹2,449.77 in materials in the worked example) tells you whether placement was the cause.

About this guide: part of CSI's cluster on 10–12 cm jars and multi-wick problems (4261–4280). It answers one question, how to position three wicks evenly in a 12 cm jar, with a paper placement template (120° marks at a labelled starting circumradius), a way to fix the tabs and hold the tops, a six-distance re-check after the pour and a costed four-candle check of whether placement was the cause of an uneven pool.

Non-price figures: load is a percentage of total candle weight (800 g at 8% = 64 g oil + 736 g wax; the standard 150 g candle at 8% = 12 g). The 12.0 cm and 11.3 cm inside readings (0.35 cm wall assumed for the outside reading), the ρ = r/2 start, the 800 g fill, the 118 mm disc and the ±2 mm tolerance are worked-example assumptions; distances are ρ√3, r − ρ and √(r² + ρ² − rρ). Wax depth for 800 g (7.9–8.2 cm) uses the 0.86–0.9 rule-of-thumb factor in a straight-sided jar. Ceilings are as the pages state (Citrus Lemon 6–10% for candles; CSI 464 up to 10%, pour 80–90°C): formulation limits, not regulatory ones. Decision lines are editorial judgement; the hour-per-2.5 cm rule is a commonly cited rule of thumb. Costs exclude labour, freight, packaging, jars and GST. Diwali 8 November 2026 is a calendar fact.
