Change control · Significance checklist
Six yes-or-no questions sort any jar, dye, additive or process change into four tiers: record only, confirm, partial revalidation, or revised formulation. The dividing line is simple — if the change alters the wick you need, it has made a new candle.
4 tiers
test kits ₹2,254.00 · ₹2,360.20 · ₹4,427.40 for 200 g candles · CSI live pricing, September 2026
Quick answers — read this first
When is a change a revised formulation? When it needs a different wick, load or wax to pass, or when two things changed at once. Everything else is tested and released as the same product.Which changes need no burn test? Only those the flame never meets: labels, boxes, lids, decoration outside the pool. Record them.
Is a small jar change significant? Usually tier 2. A 7.6 → 7.9 cm internal diameter is about 3.9% wider but 8.05% more melt-pool area. Test the approved wick against a control.
What do the tests cost? Tier 1 ₹2,254.00, tier 2 ₹2,360.20, tier 3 ₹4,427.40 in CSI materials. See the kits.
The short answer
Answer: Tier 0 record · Tier 1 confirm (same type, same amount) · Tier 2 partial (pool, geometry, end of life or process) · Tier 3 revised formulation (new wick, load or wax, or 2+ changes).
Checklist: Q1 pool · Q2 jar space · Q3 wick holding and end of life · Q4 process · Q5 the wax itself · Q6 needs a new wick, load or wax to pass.
Rule: Start at the tier Q1–Q5 give; a failure or a new wick moves it up. Nothing moves down. Two changes at once = tier 3 — see the two-changes post.
In this guide
The four tiers, from changes the flame never meets to changes that alter the wick you need. Each band names the kind of change, examples from this cluster and the priced CSI test kit for 200 g candles. Changes only move up: a failure, or a pass that needs a new wick, load or wax, lifts the change to the next tier. Candle counts are labelled working practice.

Straight answer
Which changes to jars, dyes, additives or production methods are significant enough that I should treat the candle as a revised formulation?
Treat the candle as a revised formulation when the change needs a different wick, fragrance load or wax to pass — or when two or more things changed at once. Below that line, a change is tested and released as the same product, at a level set by how close it gets to the flame. Tier 0: nothing the flame meets — labels, lids, decoration outside the pool — record it. Tier 1, confirm: same type and amount of something already in the pool, such as a dye brand at a matched shade and dose — three changed candles against three controls. Tier 2, partial revalidation: anything that changes what the pool carries (more dye, mica, an additive), the space the flame burns in (internal diameter, height, taper, base, glass), what holds the wick (tab, adhesive) or how the batch is made (mixer, 20 kg batches) — test the approved wick through full life. Geometry is bigger than it looks: 7.6 → 7.9 cm is 8.05% more melt-pool area. If a tier-2 test fails, or passes only with a new wick, load or wax, the candle becomes tier 3: a new version with its own specification and retained samples. CSI test kits for 200 g candles cost ₹2,254.00, ₹2,360.20 and ₹4,427.40.
One line: if a change alters the wick you need, it has made a new candle — everything else is a tested, recorded change to the same one.
Whatever tier your change lands in, the test candles are the same ingredients. A tier-1 confirmation (6 candles) costs ₹2,254.00, a tier-2 partial revalidation (7 candles to full life) ₹2,360.20, and a tier-3 wick bracket (14 candles) ₹4,427.40 — all in Luxury Soy Wax Chunks with Cinnamon Vanilla at 8% in White Matte jars, at CSI's listed prices.

What "revised formulation" should mean in a small candle business
Every change is a change. Only some of them make a different candle.
A revised formulation is not a label for any change you made. It is a decision: this candle is now a new version, with a new specification, new retained samples and a full test record of its own, and the old test file no longer describes it. You want that decision to be rare enough that it means something and firm enough that nobody can quietly skip it. Treat every dye top-up as a new formulation and the word stops meaning anything; treat nothing as one and your approvals describe candles you no longer make.
So this page gives you four tiers and a short checklist that sorts any jar, dye, additive or process change into one of them. The tiers use the vocabulary the whole series uses — KEEP, CONFIRM, REPEAT, NEW — and each has a priced CSI test kit. The checklist is built on one idea: a change matters in proportion to how close it gets to the flame and to the wick decision. Changes the flame never meets need a record, not a test. Changes that alter what the wick burns, or the space it burns in, need proof. Changes that alter which wick you need make a new candle.
The CSI principle
If a change alters the wick you need, it has made a new candle.
That is the line between partial revalidation and a revised formulation. Everything below it can be tested and released as the same product; everything above it is a new version with its own record.
The six-question checklist
Answer each question yes or no for the one change you are making. The highest tier any "yes" points to is the tier of the change. If you are making two changes at once, score them separately — and then read the two-changes post, because two changes together always sit at the top tier until they are separated.
One change at a time · the highest tier any "yes" reaches wins
Significance checklist for jar, dye, additive and process changes
| # | Question | If yes, at least | Examples from this cluster |
|---|---|---|---|
| 1 | Does anything new or different reach the melt pool? | Tier 1 — Tier 2 if it does not dissolve, or the amount rises | dye brand (T1) · more dye, mica in the pool (T2) |
| 2 | Does the space the flame burns in change — internal diameter, height, taper, base, glass? | Tier 2 | 7.6 → 7.9 cm · taller jar · frosted glass · taper |
| 3 | Does anything that holds or ends the wick change — tab, adhesive, base? | Tier 2 (full life) | adhesive · thicker base |
| 4 | Does the way the batch is made change — mixing, batch size, hold time? | Tier 2 (process) | mixer · 20 kg batches |
| 5 | Does the wax itself change — blend, additive, crystallisation? | Tier 2, and plan for Tier 3 | hardness additive · anti-frosting |
| 6 | Does the change need a different wick, load or wax to pass? | Tier 3 — revised formulation | Any of the above, once the wick moves |
| — | All six are no: the change is outside the pool, the jar interior and the process | Tier 0 — record it | Label, box, lid, mica on the tin exterior |
Question 6 is the only one you cannot answer before testing, which is why the tiers escalate. You start at the tier questions 1–5 give you, run that tier's test, and if the approved wick fails — or only passes after a change of wick, load or wax — the candle moves to tier 3. It never moves the other way: a tier-2 change that happens to pass easily is still recorded as a tier-2 change.
The change that got scored by its size. "It's only a 3 mm wider jar" and "it's only a little more black" are the two most common reasons a change skips testing. Size is not the test; closeness to the flame is. A 3 mm change in internal diameter is a geometry change the wick was sized for, and a little more dye is more non-wax material in every burn. Score the change on the checklist, not on how small it feels.
Putting numbers on a jar change
A few millimetres of diameter is a much bigger change in the surface the flame has to melt.
Jar changes are the one place in this cluster where arithmetic helps you judge significance before any candle is poured. The melt pool is a circle, so its area is π × d² ÷ 4 and it grows with the square of the internal diameter. The example in the 7.6 to 7.9 cm post is a 0.3 cm change in diameter, about 3.9% — but the surface area rises from 45.36 cm² to 49.02 cm², which is 8.05%. The table runs the same sum for other replacements. Dimensions here are illustrative; CSI publishes no internal diameters for its jars, so measure your own old and new jars.
Melt-pool area = π × d² ÷ 4 · base jar 7.6 cm internal diameter (illustrative)
How much bigger the surface gets
| New internal diameter | Diameter change | Old area | New area | Area change |
|---|---|---|---|---|
| 7.7 cm | 1.3% | 45.36 cm² | 46.57 cm² | 2.65% |
| 7.8 cm | 2.6% | 45.36 cm² | 47.78 cm² | 5.33% |
| 7.9 cm | 3.9% | 45.36 cm² | 49.02 cm² | 8.05% |
| 8.0 cm | 5.3% | 45.36 cm² | 50.27 cm² | 10.80% |
| 8.2 cm | 7.9% | 45.36 cm² | 52.81 cm² | 16.41% |
What area change is too much for your wick? CSI publishes no wick-to-diameter chart, and there is no honest universal number. The practical rule is to write your own threshold down before you need it — a figure you are prepared to defend — and to treat any change in internal diameter as at least a tier-2 test of the approved wick. The table is there so that everyone in the business is judging the same number: the area the flame has to melt, not the diameter printed on a supplier's listing.
What each tier keeps and repeats
KEEP · CONFIRM · REPEAT · NEW by tier
The retest matrix, tier by tier
| Earlier result | Tier 0 | Tier 1 · confirm | Tier 2 · partial | Tier 3 · revised formulation |
|---|---|---|---|---|
| Fragrance load and scent approval | KEEP | KEEP | KEEP, CONFIRM throw | REPEAT if wax or wick changed |
| Wick size | KEEP | KEEP | KEEP — tested, not changed | NEW — wick bracket |
| Early burns (3 cycles) | KEEP | CONFIRM 3 vs 3 | REPEAT 3 vs 3 | REPEAT across the bracket |
| Full-life burn | KEEP | CONFIRM one candle | REPEAT every test candle | REPEAT on the chosen wick |
| Appearance and colour | KEEP | CONFIRM | CONFIRM or NEW | REPEAT |
| Storage and stability | KEEP | CONFIRM if colour | CONFIRM | REPEAT |
| Specification and version | Record | Record | Record + retained sample | New version, new spec, new samples |
Tier 3 is not a punishment, it is a version number
Calling a candle a revised formulation does not mean it failed. It means the candle on the shelf is now Rose Heart v2, not v1, and its approval belongs to v2. Give it a version, keep v1's retained samples, and write down what changed. The specification post and the formula-record post show the fields; the change-control form gives the one-page record.The priced kit for each tier
All three kits use 200 g candles — 16 g of Cinnamon Vanilla and 184 g of Luxury Soy Wax Chunks at 8% — in White Matte Glass Jars, with a 5% pour-loss allowance (a working assumption). Candle counts are labelled working practice. Wax and oil are CSI live pricing pulled 24 September 2026; jars and wicks are Blog 760's verified figures, with wick packs rechecked on 25 September 2026.

The tier-3 wick bracket uses three different listed CSI wicks purely as three options to compare — Eco Thin C1, Eco Thick C2 and Cotton Braided. CSI publishes no sizing chart and no equivalence between them; in your own bracket, use your approved wick and its nearest alternatives. The money difference between the tiers is modest. The real difference is time: a tier-2 or tier-3 test is measured in full candle lives, which is why sorting a change correctly on day one matters more than the kit price.

Running a change through the checklist
1
Write the change in one sentence"Jar internal diameter 7.6 → 7.9 cm, same supplier, same fill." If you cannot write it in one sentence, it is probably two changes — split it.
2
Answer the six questionsTake the highest tier any "yes" reaches. For a jar, work out the area change as well; for a dye or additive, record the amount in grams.
3
Pour the tier's kit against a controlThe control is the approved candle, made with the old material or a retained sample. Change one variable only. Follow the wax maker's instructions for temperatures.
4
Score against the controlMelt pool, flame, mushrooming, soot, jar-side reading, consumption, throw, and the lines specific to the change. CSI publishes no numeric flame-height or jar-temperature limit, so every safety line passes on "no worse than the control".
5
Escalate if neededA failure, or a pass that needs a new wick, load or wax, moves the change up a tier. Run that tier's test; do not patch the lower one.
6
Release and record at the final tierTier 0–2: record the change and the result. Tier 3: new version number, new specification, new retained samples, old version's samples kept.
Score every tier the same way · C = approved control · X = changed candle
Universal scoring sheet
| Line | How | Pass if |
|---|---|---|
| Melt-pool diameter and depth at 3 h | Ruler, skewer | X within the spread of C |
| Time to full melt pool | Minutes from lighting | X no slower than C |
| Flame height, mushrooming, soot | Card scale, 0–3, white card | X no worse than C |
| Jar-side reading at 3 h | Same thermometer, same spot | X no hotter than C |
| Consumption, g/h | Weight loss ÷ hours | X within the spread of C |
| Throw, fixed room (1–5) | Same judge | X within one point of C |
| End of life: tunnelling, wax left, tab | Final burns, weigh | X within the spread of C (tier 2–3) |
| Change-specific line | From the sibling post | As that post defines |
The acceptance line on every safety row is the same across the series: no worse than the approved control, within your jar supplier's guidance and the candle fire-safety standard you work to — ASTM F2417 is a commonly cited US example, and we quote no numbers from it. A better throw never buys a hotter jar or a bigger flame, at any tier. The hotter-jar post explains why.
Three changes, scored
Worked examples from this cluster
How the checklist sorts real changes
| Change | Questions answered yes | Starting tier | What would move it up |
|---|---|---|---|
| Liquid red dye, new brand, matched shade at the same dose | 1 (dissolved dye, same amount) | Tier 1 | Shade only matches at a higher dose → Tier 2 |
| Jar internal diameter 7.6 → 7.9 cm (+8.05% area) | 2 | Tier 2 | Approved wick tunnels or overheats → new wick → Tier 3 |
| 2 kg → 20 kg batches in a larger melter | 4 | Tier 2 | Last-pour candles need a higher load to match → Tier 3 (and a process fix first) |
| Hardness additive at 5% of the wax (illustrative) | 1, 5 | Tier 2 | Only the next wick passes → Tier 3 |
| Shimmer moved from the wax to the tin lid | none | Tier 0 | Nothing — the pool never meets it |
Argued against our own interest, plainly. The cheapest tier is the one you never enter. Several changes on this page can be avoided rather than validated: keep the jar you have by ordering further ahead, put decoration outside the pool, stay with a dye that has passed, fix a frosting complaint with a label line rather than an additive. We sell the materials for every kit on this page, and we would still rather you ran a tier-0 change than a tier-3 one. Test what you must change; do not change what you can keep.

This checklist closes the jar, dye, additive and process cluster. The next part of the series turns it into a system: the 20-SKU post decides which SKUs get the full test and which a confirmation, and the change-control system post puts supplier changes, substitutions, retesting, approval and release into one routine for a small candle business.
Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. We sell the materials in every kit on this page, and we still recommend avoiding a change wherever you can keep what you have. The tiers exist to make testing proportionate, not to sell test candles.
Wax and oil prices come from live CSI listings pulled on 24 September 2026; jar and wick prices are Blog 760's figures verified on 10 September 2026, with wick packs rechecked on 25 September 2026. Melt-pool areas (π × d² ÷ 4), kit quantities, pack rounding and totals are arithmetic, shown in full; jar diameters are illustrative because CSI publishes none.
The tiers, questions, candle counts, burn cycles and 5% loss allowance are working practices for small candle businesses, not a standard. CSI publishes no wick-to-diameter chart and no numeric flame-height or jar-temperature limit; judge every line against your approved control and the fire-safety standard you work to.

Frequently asked questions
What counts as a reformulation in candle making?
A useful working definition: any change that needs a different wick, fragrance load or wax to pass testing, or two or more simultaneous changes. That candle is a new version with its own specification and test record.
Do I need to retest if I change candle jars?
Almost always, at least tier 2. Any change to internal diameter, height, taper, base or glass changes the space the flame burns in. Compare the area change and test the approved wick through full life.
Does changing candle dye count as a new formula?
A like-for-like dye at a matched shade and dose is a tier-1 confirmation. More dye, a pigment such as mica in the pool, or a change that needs a new wick moves it up — see the darker-dose post.
Is a process change like a new mixer a formulation change?
Not in itself — it is a tier-2 process change tested against the old process. It becomes a formulation change only if you alter the recipe to make the new process pass, which you should avoid.
How much bigger can a jar be before I need a new wick?
There is no published universal threshold, and CSI publishes no wick-to-diameter chart. Work out the melt-pool area change, set your own written threshold, and test the approved wick for any change.
Should I give a revised candle a new version number?
Yes. A version number keeps the old approval with the old candle and the new approval with the new one. The formula-record post shows the fields to record.
Proportionate testing
Score the change, test at its tier, and let a failure — never a feeling — move it up.

Melt-pool area = π × d² ÷ 4; jar diameters are illustrative — CSI publishes no internal diameters or wick-to-diameter chart. The 200 g White Matte fill is not published — confirm by a weighed pour. Wick equivalence between Eco Thin C1, Thick C2 and Cotton Braided is not published. The tiers and checklist are a working method. Test conventions on this page — at least 3 candles per variant, one variable changed at a time, burn cycles of about 3–4 hours with full cool-down, cure checkpoints of 48 hours, 7 days and 14 days, a full-life burn to the end of usable wax — are labelled working practices you may change, not standards. The 5% pour-loss allowance is a working assumption. CSI publishes no numeric flame-height or jar-temperature limit. Acceptance on every safety line is "no worse than the approved control" and within your jar supplier's guidance and the recognised candle fire-safety standard you work to (ASTM F2417 is a commonly cited US example). Prices and availability change — the linked product pages are always authoritative.
