CSI Diagnostics · Acceptance Gates
Burn to about 1 cm left, through four gates on the way down, on three candles plus one kept back. Any safety failure at any gate decides it, however good the first burns looked.
4 gates
first full pool, halfway, final third and the stop at about 1 cm · CSI live pricing, September 2026
Quick answers — read this first
How far down should I burn a test candle? All the way to the common-practice stop, about 1 cm of wax left. The combination is not acceptable until candles have passed four gates on the way down: the first full pool, halfway, the start of the final third, and the stop. The first half of the jar tells you least about safety.What do I record at each gate? Gate 1: time to a full pool, depth, flame, soot. Gate 2: depth and flame against gate 1, carbon, soot, a glass reading, any hard wax at the glass. Gate 3: whether the flame stays clear of the glass, wick centring, soot and whether the glass reading keeps climbing. Gate 4: every final-third burn passed, the glass inspected, and no early drowning.
How many candles per combination? In our judgement, three burned through every gate to the stop, at least one of them on long burns (up to about four hours), plus one retained unburned. Two is enough while you are still developing; three is the minimum we would sell on.
What does it cost? Worked example, Ylang Ylang in CSI 464, 150 g jar, C2: ₹1,012.63 of materials for one approval set of four candles, ₹506.31 for a development pair, excluding labour, freight, packaging and GST.
The short answer
How far: to about 1 cm left (common practice), through four gates. Nothing above the final third can approve a combination on its own.
Pass rule: any safety fail at any gate (flame touching glass, wick drifting to the wall, lasting soot, a glass reading that keeps climbing, a crack) fails the combination, however good the throw.
How many: three candles to the stop, one on long burns, plus one retained. A performance miss on one candle: pour two more. Two misses: fail.
The cost: ₹1,012.63 per combination in materials (worked example), excluding labour, freight, packaging and GST.

Straight answer
How far down should I burn a test candle before deciding the wax, wick and jar combination is commercially acceptable?
To the end of its safe life: about 1 cm of wax left, the stop many makers use (common practice). Burning less than that approves the part of the candle that was least likely to fail. The flame, the pool and the glass all change as the level falls, and the faults that matter most for a commercial candle, a flame reaching the glass, a wick drifting to the wall, soot, a jar that keeps getting hotter, belong to the final third. So judge the candle at four gates: the first full pool on burn 1, halfway, the start of the final third, and the stop. Record the same things at each, so each gate can be compared with the one before. Any safety failure at any gate fails the combination, whatever the throw was like. And judge more than one candle: in our judgement, three burned all the way to the stop, at least one of them on long burns of up to about four hours, plus one kept unburned as a reference. A combination is the wax, wick, jar, oil and load together; change any one and the gates start again.
One line: burn to about 1 cm through four gates, on three candles plus one retained, and let any safety failure on the way down decide.
One approval set, worked example: four 150 g jars from a pack of ten (₹944.00), four Eco C2 wicks from a pack of ten (₹94.40), and 48 g of oil. Jars and wicks are in stock on 26 September 2026.

Why the top half can't approve a combination
The first pool tells you whether the wick is big enough. The final third is where you find out whether it is too big.
Early burns answer one question well: can this wick melt this jar to the glass? They say little about the other side of the balance. As the level falls, the glass above the pool warms, the pool can deepen, the flame can grow, and the flame sits lower in a narrower column of air. None of that has happened at gate 1. A candle can pass its first three burns beautifully and fail at gate 3, and that is exactly the failure that turns into complaints, returns and, in the worst case, a cracked jar. The commercial case, in terms of liability and returns, is why final-third testing matters; the mechanism is the late-flame hub.
There is also a floor. Burning below about 1 cm puts the flame close to the glass floor, which is why many makers stop there and print it on the care card. Testing below the stop tests a use you are telling customers not to make, and a candle that goes out in its tab zone below the stop is behaving as designed (the tab-zone check).
A combination is five things
Wax, wick, jar, oil and load. A new oil in an approved jar and wick is a new combination, because oils change how a wick burns (tendency). A new batch of the same jar is not a new combination, but measure a few jars from it: mass-produced glass varies between batches, and a thicker base or narrower neck changes the gates.Marking the jar: where each gate sits
Gates are heights, not burn numbers. Mark them before the first light.
Measure the wax column once the candle has set: the height of the wax surface above the inside floor. (Outside height of an empty jar minus its inside depth gives the base thickness; measure the wax surface on the outside of a clear jar and subtract it.) Then mark the outside of the jar with a fine marker or a strip of tape:
Gate marks · worked example
For a wax column of 60 mm above the inside floor (worked example; use your own) · heights in mm above the inside floor
| Gate | Where | Worked example | When you reach it |
|---|---|---|---|
| 1 · First full pool | The first burn | 60 mm (the full candle) | Burn 1 |
| 2 · Halfway | Half the wax column | 30 mm | The first burn that ends at or below the mark |
| 3 · Final third | A third of the wax column | 20 mm | Every burn from here to the stop is a gate-3 burn |
| 4 · Stop | About 1 cm (common practice) | 10 mm | End of the test; don't burn below it |
For scale: the 150 g jar's page lists a height of 8 cm, which is outside height with no fill line stated; your wax column will be shorter. In a shallow jar the gates sit close together, and gate 3 may arrive within a few burns of gate 2. That is not a reason to skip gate 2; it is a reason to log every burn.
The four gates: what to record, what passes
Record the same things at every gate, so each gate is a comparison, not a snapshot.
1
Gate 1 · first full pool (burn 1)Record minutes until the pool touches the glass all round, pool depth at the end (a skewer at the wall), flame height against a ruler behind the jar, flicker, soot, carbon, and whether the wick is centred. Commonly cited rules of thumb: a full pool within about 3–4 hours and about 0.5–1 cm deep. Passes if the pool reaches the glass inside the burn and the flame is calm. A first burn that stops short sets a memory ring; on one candle that is a performance miss (two more candles, per the set rule below), and if it repeats the fix is a wick bracket, not a longer first burn.
2
Gate 2 · halfwaySame records, plus a glass reading at one marked spot with a non-contact thermometer at the end of the burn (CSI does not list one; never judge by touch), and any hard wax left at the glass. Passes if depth and flame are close to gate 1, no wall of wax is forming, no soot band, and carbon clears with normal trimming.
3
Gate 3 · every burn in the final thirdSame records every burn, and watch the flame's distance from the glass and the wick's position. Passes if the flame never touches or leans onto the glass, the wick stays near the centre, there is no lasting soot, and the glass reading at the same point in the burn is not rising burn after burn. The safety criteria in full, and what fails a wick however good the throw, are the hot-jar post.
4
Gate 4 · the stop, about 1 cmPut the candle out at the mark. Once cool, inspect the glass (base and walls) for cracks or crazing, note the wick stub and any debris, and record whether the flame drowned before reaching the mark. Passes if every gate-3 burn passed, the glass is sound, and the wick did not die well above its tab.
5
Throughout · the conditions lineFor every burn: date, burn length, room, draught, trim length (the trimmer page suggests "Trim your wick to 1/4 inch before every burn"), and who logged it. Burn within sight, never unattended. Without this line, a failure cannot be told apart from a draught.
Gate log · one line per burn
Copy this into your batch sheet · a dash means "not needed at this gate"
| Record | Gate 1 | Gate 2 | Gate 3 (every burn) | Gate 4 |
|---|---|---|---|---|
| Wax height above the inside floor, before and after | Yes | Yes | Yes | Yes |
| Minutes to a full pool | Yes | Yes | Yes | — |
| Pool depth at the end (skewer) | Yes | Yes | Yes | — |
| Flame height, flicker, lean | Yes | Yes | Yes, plus distance to the glass | — |
| Carbon on the wick, soot on the glass | Yes | Yes | Yes | Wick stub and debris |
| Glass reading, same spot, same point in the burn | Optional | Yes | Yes | — |
| Wick position (centred, drifting, leaning) | Yes | Yes | Yes | — |
| Glass inspection (cracks, crazing) | — | — | — | Yes |
| Throw score on entering the room (0–3), optional | Yes | Yes | Optional | — |
Throw appears in the log but not in the pass rules. That is deliberate: this page decides whether a combination is safe and burns properly to the end. Whether it smells strong enough is a separate question with its own tests, in the cold-strong, hot-faint hub; a combination that throws beautifully and fails gate 3 is still a fail, and one that passes every gate but throws weakly goes back to the formulation, not to a bigger wick.
Mistake: treating gate 3 as one burn. What it misses: the final third is several burns, and heat builds as it goes; the last burn before the stop is often the hardest. Fix: every burn below the gate-3 mark is judged against the gate-3 criteria, and one failure is enough.
How many candles per combination
One candle that passes could be a good pour. Three that pass is a combination.
CSI publishes no required number. What follows is our judgement, built on one idea: a combination must pass on candles you did not choose because they looked good.
Candles per combination · judgement
Worked example: Ylang Ylang in CSI 464, 150 g jar, C2 · 150 g at 8% of total weight · CSI live pricing, 26 September 2026
| Stage | Candles | What they do | Oil and wax | Materials |
|---|---|---|---|---|
| Development pair | 2, both to the stop | Duplicates for a wick bracket or a first look | 24 g + 276 g | ₹506.31 |
| Approval set | 3 to the stop + 1 retained | Two on your usual burns, one on long burns up to about 4 h; one kept unburned | 48 g + 552 g | ₹1,012.63 (₹253.16 per candle) |
| A five-scent range, one jar and wick | 20 | One approval set per scent | — | ₹5,063.14 (Ylang Ylang's price used for all five, illustrative) |
The long-burn candle is there because a combination that passes only on short burns has passed half a test (the two-hour versus longer-burn post explains why). The retained candle is there for later: when a future batch behaves differently, an unburned candle from the approved batch is the reference that tells you whether anything changed (the same-formula, weaker-batch hub). Cost figures are materials only and exclude labour, freight, packaging and GST; starting from nothing, one set's cash outlay is ₹1,876.20.
For the approval set: 12 g of oil and 138 g of wax per 150 g candle at 8% of total weight (8% of total is 8.70% of wax weight), inside Ylang Ylang's "Up to 10% for soy wax" and CSI 464's "up to 10%" even if read on wax weight (9.09% of total). Pour at 80–85°C in the 150 g jar (CSI 464 states 80–90°C; the jar page "Safe for hot pour up to 85°C"). Ylang Ylang's page gives "Cure Time: 48–72 hours for soy wax"; many makers start at day 7 (common practice).
Deciding on the set · judgement
Safety gates are pass/fail; performance gates allow one retest
| What happened across the three burned candles | Verdict | Next |
|---|---|---|
| All three pass all four gates | Accept the combination | Write the spec; keep the retained candle |
| Any safety fail (flame on glass, wick at the wall, lasting soot, climbing glass reading, crack), on any candle | Fail | Change one thing (usually the wick) and run a new set |
| One performance miss (a thin memory ring, a slow pool) on one candle | Undecided | Pour two more; accept only if both pass |
| Two or more performance misses | Fail | Back to the bracket |
When a gate fails: what it points to
The gate where it failed is the first clue to why.
Gate failure → likely cause → where it is diagnosed
Most common first within each gate (judgement)
| Gate | Failure | Likely cause | Where it goes |
|---|---|---|---|
| 1 | Pool short of the glass | Wick too small for this jar and oil | A wick bracket (2726) |
| 1 | Tall flame, soot on burn 1 | Wick too large, or load near the ceiling | Step down; check load |
| 2 | Pool much deeper than gate 1 | Over-wicked for the lower section | The depth chart |
| 2 | Wall of wax forming | Memory from a short early burn | Burn-length twins |
| 3 | Flame growing, touching or leaning on the glass | Heat building low in the jar; wick too large there | Final-third criteria; narrowing jars |
| 3 | Wax used faster each burn | Heat accumulating | The weigh-per-burn log |
| 4 | Drowned well above the tab | Pool, debris, clogging or jar shape | The tab-zone check |
| 4 | Crack or crazing in the glass | Thermal stress, flame contact, a flaw | The cracked-jar forensics |
A fuller list of what only shows up late, and which test in this cluster catches each fault, is the late-life failure catalogue. If you are approving many scents at once, don't run a full set for every candidate from day one: the tiered 20-fragrance plan screens first and saves the full burn-down for survivors, without skipping it.
What not to buy: a bigger bottle of the oil before the combination passes (Ylang Ylang's 1 kg is ₹5,310.00; one set needs 48 g); a new jar because gate 3 failed, before trying a smaller wick in the same jar; a probe or pen thermometer to read glass: CSI's Pen Thermometer (₹354.00) is described for "the temperature of your candle wax", and CSI does not list a non-contact one. Twenty jars for one combination: four is enough to decide; more candles on a failing combination only make the failure more expensive.
When the right purchase is nothing: if you already have three unburned candles from the batch you want to approve and one to retain, the set costs nothing new. Mark them, burn them to the stop and log every gate.
Jar, wick, oil and wax for an approval set
Four items for one worked-example combination. Chosen on page statements, price per unit and stock on 26 September 2026; CSI has no measured burn data, so nothing is ranked on performance. The oil table shows every size, 150 g candles at 12 g, and 48 g approval sets.
1
jar · the worked-example vessel
Clear Glass Jar with Golden Lid (150 gram)
Every gate is judged in a specific jar, and a combination approved in one jar is not approved in another. The page describes "Premium thick-walled clear glass", a "150g fill capacity", "Height 8cm, outer diameter 7cm", a base of approximately 6.5 cm and "Safe for hot pour up to 85°C". Clear glass lets you see the tab, the pool wall and any wick drift at gate 3 without disturbing the candle. It states no internal diameter, and glass varies between batches, so measure a few jars from each batch you buy. Argued against our own interest: if you sell in a different jar, test in that jar; buying this one for a trial proves little about yours.
| Size | Price | Per unit | What it covers |
|---|---|---|---|
| Pack of 10 | ₹944.00 | ₹94.40 | one approval set of four, six spare for a second combination |
| Pack of 20 | ₹1,888.00 | ₹94.40 | the same per jar; five combinations at four jars each |
One approval set: ₹377.60. Buy 10 — ₹944.00
2
wick · the worked-example wick and its step down
Eco Candle Wicks — Thick (C2) and Thin (C1)
The approval set carries the wick that won your bracket; the worked example uses C2. The page describes wicks from "natural fibers like cotton and paper" that "pair perfectly with soy wax", and names no jar diameter for either size; the 200 ml Salsa jar pages say "Pairs well with C2 Eco Wicks", a starting rung only. Every pack is in stock on 26 September 2026, and the price per wick is the same at every pack size (₹9.44 for C2, ₹5.90 for C1). Argued against our own interest: a set that fails gate 3 needs a step down and a new set, not more of the same wick; buy packs of ten until a combination has passed gate 4.
| Size | Price | Per unit | What it covers |
|---|---|---|---|
| Thick (C2) / 10 | ₹94.40 | ₹9.44 | one approval set, six spare |
| Thick (C2) / 20 | ₹188.80 | ₹9.44 | the same per wick; five sets |
| Thick (C2) / 100 | ₹944.00 | ₹9.44 | the same per wick; production only |
| Thin (C1) / 10 | ₹59.00 | ₹5.90 | the step down if a set fails in the final third |
One set: ₹37.76 in wicks. Buy C2 — ₹94.40
3
fragrance oil · white floral · the worked-example oil
Ylang Ylang Flower Fragrance Oil
The oil is part of the combination: change it and the gates start again, because oils can change how a wick burns. The page states "Recommended Fragrance Load: Up to 10% for soy wax Up to 6% for paraffin wax", "Cure Time: 48–72 hours for soy wax", and "Wick Recommendations: Cotton or wooden wicks are ideal for even burns and maximizing scent throw. Test wick size to suit container dimensions." That last sentence is this page in miniature. It describes the oil as "Sweet, rich, and floral with creamy undertones", "Fragrance Strength: Moderate to strong" and "Vanillin Content: 0% (No discoloration risk)" (the page's wording; test anyway). Every size is in stock on 26 September 2026; the 50 g covers one approval set with 2 g spare. Argued against our own interest: the 1 kg is ₹118.00 cheaper than two 500 g packs and ₹5.31 a gram against ₹6.61 at 50 g, but a set needs 48 g; a candle's 12 g costs ₹79.30 at the 50 g price and ₹63.72 at the 1 kg price. Buy volume only after the combination has passed.
| Size | Price | Per gram | 150 g candles at 8% | Approval sets (48 g each) |
|---|---|---|---|---|
| 15 g | ₹106.20 | ₹7.08 | 1 | none (15 g of the 48 g) |
| 50 g | ₹330.40 | ₹6.61 | 4 | 1 (+2 g) |
| 100 g | ₹590.00 | ₹5.90 | 8 | 2 (+4 g) |
| 500 g | ₹2,714.00 | ₹5.43 | 41 | 10 (+20 g) |
| 1 kg | ₹5,310.00 | ₹5.31 | 83 | 20 (+40 g) |
One set: 48 g = ₹317.18. Buy 50 g — ₹330.40

wax · container soy · the worked-example wax
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", and claims "excellent glass adhesion" and "Low frosting, minimal blooming"; wet spots and frosting are cosmetic, not gate failures. Price is flat at ₹0.51 per gram from 1 kg to 10 kg. Argued against our own interest: if your candles are poured in another wax, the approval must be in that wax; a combination is only as transferable as its least-shared ingredient.
| Size | Price | Per unit | What it covers |
|---|---|---|---|
| 500 g | ₹260.00 | ₹0.52 per g | not enough for one set (552 g) |
| 1 kg | ₹507.40 | ₹0.51 per g | one set, 448 g left |
| 5 kg | ₹2,537.00 | ₹0.51 per g | the same per gram; several combinations |
| 10 kg | ₹5,074.00 | ₹0.51 per g | the same per gram; production |
One set: 552 g = ₹280.08. Buy 1 kg — ₹507.40

The CSI principle
A combination is approved at the stop line, not at the first pool.
Four gates on the way down, three candles through all of them, one kept back. Any safety failure anywhere decides it.
"The top of the jar tells you whether the wick is big enough. The bottom tells you whether it is safe."

Why trust this guide
CandleMakingSuppliesIndia sells the jars, wicks, wax and oil named here, and does not sell finished candles. This page still tells you that four jars are enough to decide a combination, that our pen thermometer is not a glass thermometer, that one approval set needs 48 g of oil, not a 1 kg bottle, and that existing candles from your batch make the set free.
Every price and per-unit figure was verified on CSI's live store on 26 September 2026; every size in the pick tables is in stock on that date, and the tables are built to flag any that is not. Load, cure, temperature and jar wording is quoted from the product pages; where a page is silent in the text we captured (internal diameters, fill lines, wick diameter ranges), we say so.
The gates, the candle counts and the decision rules are editorial judgement; the melt-pool times and depths are commonly cited rules of thumb; the 1 cm stop and four-hour burn are common practice; the 60 mm column is a worked example; CSI publishes no burn measurements or approval standard.

Frequently asked questions
How far down should you burn a test candle?
To about 1 cm of wax left, the stop many makers use. Judge it at four points on the way: the first full pool, halfway, every burn in the final third, and the stop. In our judgement, the final third is where most safety failures appear.
How many candles should I burn test before selling?
In our judgement, three per combination burned to the stop, at least one of them on long burns of up to about four hours, plus one kept unburned as a reference. Two is fine for development; any safety failure on any candle fails the combination.
What should I record during a candle burn test?
Every burn: date, burn length, room and draught, trim length, time to a full pool, pool depth, flame height, flicker, soot, carbon, wick position and a glass reading from a non-contact thermometer. At the stop, inspect the glass for cracks.
Do I need to burn test every fragrance in the same jar?
Yes, before you sell it: oils can change how the same wick burns, so each scent is its own combination. You can screen many scents quickly first and give the full burn to the survivors, but not skip it.
When is a candle burn test a fail?
Any flame touching the glass, a wick drifting to the wall, lasting soot, a glass reading that keeps rising burn after burn, or a crack is a fail, whatever the throw. A slow pool or a thin memory ring on one candle calls for two more candles before deciding.
Why stop burning a candle with 1 cm of wax left?
Below that, the flame sits close to the glass floor and heat on the base builds. Many makers stop at about 1 cm and print it on the care card. Testing below it tests a use you advise against.
Before you approve a combination
Mark four gates, burn three candles to the stop, keep one back.
Log the same things at every gate, fail the combination on any safety failure, and pour two more on a single performance miss. One worked-example set is ₹1,012.63 in materials. Send us your gate log on WhatsApp.

Editorial standards & sources
About this guide: part of CSI's cluster on candles that burn correctly at first and then go wrong (3241–3260). This page owns the acceptance gates at depth (first full pool, halfway, final third, stop at about 1 cm), what to record at each, and how many candles to test per combination, with costs and decision rules. The late-life failure catalogue is 3260; screening 20 scents is 3259.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 — Gardenia Fragrance Oil, Lavender Fragrance Oil, White Matte Glass Jar, Woody Oud Fragrance Oil, [1 Year Warranty] Mini Electric Wax/Soap Melter (1 litre capacity).

Non-price figures: load is a percentage of total candle weight (150 g at 8% = 12 g oil + 138 g wax). Ceilings and temperatures are as stated on the product pages (Ylang Ylang up to 10% for soy wax, cure 48–72 hours for soy; CSI 464 up to 10%, pour 80–90°C; 150 g jar hot pour up to 85°C, height 8 cm) and are formulation limits, not regulatory limits. The 60 mm wax column and gate heights are a worked example. Melt-pool times and depths are commonly cited rules of thumb; the 1 cm stop and four-hour burn are common practice. Gates, candle counts and decision rules are editorial judgement. Costs exclude labour, freight, packaging and GST. Diwali 8 November 2026 is a calendar fact.
