CSI Diagnostics · Same Formula, Weaker Batch
A formula is a recipe; a batch is what happened on the day. Before you blame the wax, oil or wicks, put last month's batch beside this month's on paper, then burn candles you kept from each at matched age.

Quick answers — read this first
Which raw material should I investigate first? None yet. In our judgement the commonest reasons a repeat batch throws less are the batch record and the calendar: the load actually weighed, the add and pour temperatures, and how many days old each batch was when you judged it. Check those first; they cost nothing.

Then in what order? Records and cure age, then your own oil stock (bottle age, headspace, storage), then the wick pack, then the wax bag, then the jar. That order is editorial judgement, not measured data. CSI publishes no lot or batch data; for the lot numbers on your orders, ask us on WhatsApp.

How do I test it? Put last month's batch and this month's side by side on paper (the diff sheet), then in the room: two retained candles from last month against two from this month, burned on separate evenings once this month's are as old as last month's were when you approved them.

What does that cost? Nothing new: the four candles already exist. In the worked example they carry ₹922.57 of materials (₹230.64 each), 10% of one 40-candle batch, excluding labour, freight, packaging and GST.
The short answer
The rule: a formula is a recipe; a batch is what happened on the day. Audit the batch record and the cure age before you blame a raw material.
The order: records and cure age → own oil stock → wick pack → wax bag → jar. Cheapest and, in our judgement, most common first.
The test: a diff sheet of the two batches, then a retained-candle side-by-side at matched age: two from last month, two from this month, separate evenings, same room, same nose.
The limit: CSI publishes no lot, batch or reformulation data. Your records and retained candles are the evidence; lot numbers for your orders are on request on WhatsApp.

Straight answer
I made the exact same candle formula as last month but this batch has weaker hot throw. Which raw material should I investigate first?
Start with the batch, not a raw material. First, the record and the calendar: was the oil weighed on the same basis, at the same add and pour temperatures, and were both batches judged at the same age? A repeat batch judged at day 5 against a memory of last month's at day 14 is the commonest false alarm in our judgement, and the fix is to wait. Second, your own oil stock: the same bottle can be older, emptier and warmer than it was. Then the wick pack, the wax bag and the jar, in that order, but only for rows your records show actually changed. Put the two batches side by side on paper, then burn two retained candles from each batch at matched age in the same room. CSI publishes no lot or batch data, so your records and retained candles are the evidence; ask us on WhatsApp for the lot numbers on your orders.
One line: audit the record and the cure age first, then oil stock, wick pack, wax bag and jar, and test only the rows that changed.
If the process row is "unknown": a Pen Thermometer (₹354.00) and a Weighing Scale (₹354.00) turn guesses into numbers on the next batch. Skip either if you own a working one. Both are in stock on 26 September 2026.

A formula is a recipe; a batch is an event

"Same formula" describes what you meant to do. The candle records what you did, and on which day you sniffed it.

A formula card says Sandalwood, 8%, CSI 464, C1, 150 g jar. A batch adds a dozen or more facts the card never mentions: which bag of wax and how far into it, which bottle of oil and how full, which pack of wicks, what the scale read, the temperature when the oil went in and when the pitcher was poured, how long it was stirred, how warm the room was, and how many days passed before anyone lit a candle. Any one of those can move hot throw. None of them appears on the card, so "same formula" is true and unhelpful at the same time.

That is why the question "which raw material?" usually comes one step too early. A raw material is a suspect only if your records show it changed between the batches. If both batches used the same bag, the same bottle and the same pack, the materials are shared and cannot explain a difference between them; what differed was the process or the calendar. If the records are thin, that is the first finding, and the process-fields post explains which fields would have caught it.

What CSI can and cannot tell you
CSI publishes no lot or batch release data, no oil composition and no reformulation notices, and nothing on this page implies that any CSI batch changed. What we can do is tell you the lot or batch numbers on your orders when you ask on WhatsApp, so your batch sheet can record them. Your retained candles and your records are the only evidence of what your two batches did.

For the formulation side of the same situation (a small test batch that beat a big production batch) see the 20 kg production batch investigation; for the first-level version, worked in a small test, different in bulk. This page is the diagnostic hub for a repeat of the same size that came out weaker.

Ranked suspects: pattern, cause, rule in or out

In our judgement, most "the oil changed" batches turn out to be younger, lighter or hotter than the one they are compared with.

The table ranks the causes behind a weaker repeat batch in the order we would suspect them, most common first. The ranking is editorial judgement; CSI has no failure statistics. Here the cheapest-to-check order and the most-likely order mostly coincide, because the two commonest suspects (record and cure) are also free to check. Where they part company, as with the jar (cheap to measure, rarely the cause of weaker throw in a repeat), we rank by likelihood and say so.

Differential table · same formula, weaker hot throw
Ranked most common first (judgement) · each row names the evidence that rules it in or out
# Pattern you see Likely cause Rules it in Rules it out
1 This month's batch judged within a few days of pouring; last month's approved later Cure age at test Batch B improves by the age at which A was approved B still weaker at matched age
2 More candles from the same batch weight, or a different person weighed the oil Load lower than planned (basis slip, tare, scale) Candle count, oil used and wax used don't reconcile Grams on the sheet reconcile with the bottle and the bag
3 No temperatures logged for B, or a different pot, melter or rush day Process: add or pour temperature, stir time B's figures differ from A's, or can't be found Both batches logged inside the wax page's range with the same stir
4 Same oil bottle, now half empty, weeks older, kept in a warm room Own oil stock aged in use A sealed sample kept from the first pour smells different from the bottle now The bottle still smells like the sealed sample
5 A new oil order went into batch B New order differs, or your old reference has aged Strip and candle checks against a retained sample Retained candles of A and B match at matched age
6 A new wick pack, and B's pools are smaller or shallower Wick lot Pool and flame differ in the side-by-side; physical checks differ Pools and flames match
7 A new wax bag, and B looks or feels different, or pools differently Wax lot Unscented old-bag against new-bag twins differ Twins match
8 A new jar delivery Jar dimensions changed the pool Internal diameter differs by measurement Same measurements, same pool
9 Both batches smell weaker than you remember Your nose, room or memory, not the candles A retained candle from A is also faint now A throws as it did when approved

Rows 1 to 3 need nothing but your batch sheet and a calendar. Rows 4 and 5 are the oil, split deliberately: your own stock ageing in use is handled by the own-stock audit, and a new order by the new-order gate, which uses the incoming-batch comparison as its method. Rows 6 to 8 are the materials the title asks about. Row 9 is why a retained candle matters: it is the only witness that does not rely on memory.

Mistake: comparing this month's candle with your memory of last month's. What tends to happen: memory keeps the best burn in the best room; the new candle is burned on a busy evening with the fan on. Fix: only a retained candle from last month, burned in the same room under the same rules, can say whether this month's batch is weaker. If you kept none, start keeping two from every batch today; the batch-sheet template gives them a code.

The basis slip, worked

Row 2 is the quiet one. Last month you weighed a 40-candle batch at 8% of total weight: 480 g of oil into 5,520 g of wax, 6,000 g in all. This month a helper read "8%" as oil added to wax and put 480 g into 6,000 g of wax. The batch is now 6,480 g at 7.41% of total weight, 0.59 percentage points under plan, with 11.1 g of oil in each candle instead of 12 g, and it fills 43 candles instead of 40. Each candle is short ₹4.47 of Sandalwood at the 500 g price. The candle count gave it away before anyone lit a wick. The conversion itself belongs to the load-basis hub.

The diff sheet: two batches, row by row

If your records can't say which bag, bottle and pack each batch used, that is the first thing to fix, whatever the candle is doing.

The diagram at the top is the diff sheet drawn as lanes. Here is how to build yours in about an hour from what you already have: batch sheets if you keep them, and if you don't, invoices, the labels on bags and bottles, dated photos on your phone and your order chats.

1
Two columns, one row per inputBatch A (the one you approved) and batch B (the weaker one). Rows: wax (product, bag, how far into it), oil (product, bottle, date opened, how full), wick (type, pack, date opened), jar (delivery), load and basis, grams of oil and wax, candle count, add temperature, pour temperature, stir time, room, maker, pour date, date judged, and cure age at the burn you judged.
2
Reconcile the gramsOil used plus wax used should equal the candle count times the candle weight, give or take the pot residue. In the worked example that is 480 g + 5,520 g = 6,000 g for 40 candles. If B made more candles from the same oil, the load fell. Checking the scale itself is part of the own-stock audit.
3
Mark where the stock changedA 10 kg bag of CSI 464 holds one 40-candle batch at 8% (5,520 g) with 4,480 g over, so batch B used the end of bag 1 and 1,040 g of bag 2. The 1 kg oil bottle had 520 g left after A and 40 g after B. The C1 wicks came from a new pack of 100. Each is a row that changed, in whole or in part.
4
Write "unknown" honestlyIf B's pour temperature wasn't logged, the row says unknown. An unknown row can't be cleared or blamed, and it goes near the top because the next batch can measure it. For CSI 464 the page states a pour temperature of 80°C–90°C; in the 150 g jar pour at 80–85°C, because the jar page's 85°C is the lower limit.
5
Put the cure ages side by sideDays from pour to the burn you judged. In the worked example A was judged at day 14 and B at day 5. Sandalwood's page states "a cure time of 48-72 hours" for soy; many makers judge hot throw at day 7 and 14 as common practice. Until B reaches the age at which A was approved, cure explains the difference as well as anything else.
6
Rank the changed rows by the suspect orderRecords and cure first, then own oil stock, wick pack, wax bag, jar. Test only rows that changed or are unknown; a row identical in both batches cannot explain a difference between them. Then ask us on WhatsApp for the lot numbers on the orders behind each changed row and write them on the sheet.

For the full batch record to keep from now on, see the repeatable mixing and curing protocol and, in this cluster, the traceable batch sheet. If the batches were different sizes, the sheet you need is the test-against-production version in the 1 kg to 10 kg post.

The retained-candle side-by-side

The candle you kept from last month is the only control you have that nobody can argue with.

When the diff sheet leaves more than one suspect, or none, burn the evidence. The control is last month's batch, in candles you kept unburned; the test is this month's. Everything else is held the same: room, burn length, trim, nose, scoring. The comparison needs no new materials, which is the point: you learn whether batch B really is weaker before you spend anything on finding out why.

The set and the schedule

A1 and A2: two unburned candles from last month's batch. B1 and B2: two unburned candles from this month's. Burn A1 and B1 on separate evenings in the same closed room once B has reached the age at which A was approved; in the worked example that is day 14, on 3 October 2026. Burn A2 and B2 a few days later as the duplicate. A is older than B throughout, so it is at least as cured: if B matches A, cure was the difference; if B is still weaker, cure alone does not explain it. Never burn two candles in the same room at once, because you cannot tell which one you smell.

One of each, if you kept only one from A no duplicate: treat the result as provisional ₹461.29
One 40-candle batch, for scale ₹9,225.71

All costs are material value and exclude labour, freight, packaging and GST. Burning four candles from stock is 10% of one batch's material value, and it decides whether the other 38 of batch B go on sale. If you kept no candle from A but still have last month's wax, oil and wicks, pour a reference pair from those leftovers (₹461.29 in materials) and compare it with B at matched age: weaker evidence, because the reference is newly poured, but better than memory.

The protocol

Same room, door shut, fan and AC off. Each burn runs until the pool reaches the jar edge or four hours pass; a commonly cited rule of thumb expects a full pool in about 3–4 hours, and a very rough one is an hour per 2.5 cm of width, about 2.8 hours for the 7 cm-wide jar. Log pool diameter at one, two and three hours, pool depth at the end (about 0.5–1 cm is a common target), flame height and any soot. Sniff on entering from outside at one hour, two hours and full pool, ideally a second person who doesn't know which candle is lit, and score 0 (nothing) to 3 (fills the room). Trim every wick the same way. Burn within sight.

Decision rule · retained-candle side-by-side
Read both pairs together; if the duplicates disagree, repeat before you act
What you see What it points to Next step Purchase
B matches A at matched age Cure age at test Approve B; record "judge at day 14" on the spec Nothing
B weaker; pools and flames match A's Load or oil: the scent in B is less, not released less Reconcile grams; own-stock audit (3220); new-order gate (3265) Nothing yet
B weaker; B's pools smaller, shallower or slower Wick pack or wax bag, whichever row changed Wick lot (3264); wax lot (3263); both changed: the swap-back 2×2 Nothing yet
B weaker; B's flame taller, sooty, or carbon on the wick Wick pack or oil, whichever row changed; combustion can mask scent 3264 or 3267 Nothing yet
B weaker; B's pools differ and the jar delivery changed Jar geometry Measure old and new jars (3268) Nothing yet
A is faint too Your room, nose or benchmark moved, not the batch Re-judge with a fresh nose in a smaller closed room Nothing

Every row ends in "nothing yet" or "nothing", and that is deliberate. The side-by-side tells you whether and where; the sibling posts tell you what. The only purchases this table ever routes to are a scale or thermometer for a maker without one, and whatever a sibling's test proves.

Mistake: burning A and B side by side in one room "to save time". What it does: the stronger candle masks the weaker, and you can't say which flame the scent came from. Fix: separate evenings, same room, same length, same scoring; if you must use one evening, two rooms of the same size with the doors shut, and swap rooms for the duplicate pair.

What not to buy while you investigate

A weaker batch makes people reorder. A new bag, bottle or pack can't testify about the old one.

We sell every material in this post, and we would still rather you bought nothing until the diff sheet and the side-by-side have spoken.

What not to buy yet: a fresh bottle of the same oil "in case the old one went off": it cannot tell you whether the old one changed, and it adds a third lot to a two-lot question. A new 10 kg bag of wax (₹5,074.00): the same problem, at a higher price. A stronger oil or a higher load: if cure or process caused the drop, extra oil treats the wrong thing. If you do raise the load after the evidence points there, stay inside the lower of the oil page's and the wax page's stated maximum; Sandalwood and CSI 464 both state up to 10%, which is 9.09% of total weight if the 10% is read on wax weight, so a cautious top rung is 9% (13.5 g per 150 g candle). A bigger wick "to push the throw": only if the side-by-side shows smaller pools in B.

When the right purchase is nothing: if batch B was judged before it reached the age at which A was approved, there is no evidence yet that anything changed. Wait, burn B1 against A1 at matched age, and decide then. In our judgement a good share of "same formula, weaker batch" questions end at that step, with the batch approved and nothing bought.

What to buy, suspect by suspect

Five items in suspect order: the two tools that turn process rows from "unknown" into numbers, the worked example's oil, and the wick and wax that sibling posts test. Chosen on page statements, price per gram or unit, and stock on 26 September 2026; CSI has no measured throw data, so nothing is ranked on throw. The oil table lists every size, with 150 g candles at 12 g and 40-candle batches at 480 g.

1
tool · suspect 1 lives on the scale
Candle Making Weighing Scale
The first suspect is the batch you think you made. A slip in basis (oil weighed against the wax instead of the total), a tare pressed at the wrong moment or a flat battery changes the load without changing the "formula". The page describes a digital scale showing "grams or ounces" with "simple one-button operation"; it does not state capacity or reading step in the text we captured, so check it against a known weight before trusting it (the own-stock audit has the check). Argued against our own interest: any scale that reads single grams, has a tare button and holds your pot does this job. If you have one that passes the known-weight check, buy nothing here.
Size Price Per unit What it covers
Single ₹354.00 ₹354.00 weighing oil and wax for every batch; capacity and reading step not stated
Weigh on total weight: 12 g of oil in a 150 g candle is 8%. Buy the scale — ₹354.00
2
tool · suspect 1, the temperature half
Pen Thermometer For Candle Making
In the worked example, batch B's pour temperature was never written down, so the process row reads "unknown". That is a finding, not a gap to guess. The page says it is for monitoring "the temperature of your candle wax"; it states no range or accuracy figure in the text we captured, so check it in ice water before a batch and compare it with any other thermometer you own. In CSI 464 the wax page states a pour temperature of 80°C–90°C, and in the 150 g jar, whose page says "Safe for hot pour up to 85°C", pour at 80–85°C. Log the add and pour figures every time.

fragrance oil · woody · the worked example's bestseller
Sandalwood Fragrance Oil
The page states "Up to 10% for soy wax, with a cure time of 48-72 hours", describes a "warm, creamy, luxurious single-note sandalwood" and calls it "Moderate to strong throw" (the page's wording, not a measurement). Every size is in stock on 26 September 2026. Argued against our own interest: do not reorder it because a batch came out weaker. A new bottle cannot tell you whether the old one changed in your storeroom, and CSI publishes no lot or batch data to compare against. If your bottle passes the own-stock audit and the side-by-side still points at the oil, a new order goes through the new-order gate before production. Per gram, 100 g, 500 g and 1 kg are the same ₹5.03, so the 1 kg buys convenience, not a lower price.
Size Price Per gram 150 g candles at 8% 40-candle batches (480 g)

wick · suspect 3, the wick pack
Eco Candle Wicks — Thin (C1) and Thick (C2)
If the diff sheet shows a new wick pack, the side-by-side tells you whether pools changed; the physical checks and the old-pack against new-pack burn belong to the wick-carton post. The page describes wicks made from "natural fibers like cotton and paper" that "pair perfectly with soy wax". Every pack size is in stock on 26 September 2026, and the price per wick is the same at every pack size. Don't open a third pack to "compare": it adds a lot and answers nothing about the two you have. Do not change to C2 because a batch smelt weaker unless the pool evidence says the flame is now too small.
Size Price Per unit What it covers
Thin (C1) / 10 ₹59.00 ₹5.90 two wicks for a reference pair, if you are short
Thin (C1) / 100 ₹590.00 ₹5.90 production: the same per wick
Thick (C2) / 10 ₹94.40 ₹9.44 one step up, only if the pool test says so
Thick (C2) / 100 ₹944.00 ₹9.44 production, after a C2 has passed a burn-down
Two C1 wicks for a reference pair: ₹11.80. Buy C1 — ₹59.00

wax · suspect 4, and the wax every figure here uses
Luxury Soy Wax CSI 464 (Flakes Form) For Container Candles
The page states "Fragrance Load Up to 10%", "Pour Temperature 80°C – 90°C" and claims "Strong scent throw (both cold and hot)". It is priced flat per gram from 1 kg to 10 kg; the 500 g works out at ₹0.52 a gram. A 40-candle batch at 8% takes 5,520 g, so a 10 kg bag covers one batch and leaves 4,480 g: a repeat batch routinely straddles two bags, and the diff sheet should say where the new bag started. Argued against our own interest: a fresh bag bought now answers nothing about last month's, and CSI publishes no lot data. Buy only if you need wax for a reference pair and have no leftover; the old-lot against new-lot pour is the new-wax-batch post.

500 g ₹260.00 ₹0.52 per g a reference pair from a fresh bag, if you have no leftover of last month's
1 kg ₹507.40 ₹0.51 per g the same, with enough left for a wick-step pair
5 kg ₹2,537.00 ₹0.51 per g most of a 40-candle batch (5,520 g)
10 kg ₹5,074.00 ₹0.51 per g one 40-candle batch with 4,480 g left, which is why batch B straddled two bags
Wax in one candle: ₹70.02 at the 10 kg price. Buy 500 g — ₹260.00
Diwali is 8 November 2026, 43 days from 26 September 2026. In the worked example, batch B's fair test on 3 October leaves 36 days to approve it or fix the row the side-by-side points to.

Map of this cluster: 3261–3280

This hub owns the short answer, the suspect order and the retained-candle side-by-side. Each of the other nineteen posts owns one test for one kind of change. One line per post, so you can go straight to the row your diff sheet flagged.

Cluster map · 3262–3280
Material lots (3262–3269), the season and the room (3270–3273), scale and equipment (3274–3276), people and records (3277–3280)
No. What the post answers (linked)
3262 A bestseller suddenly tunnels: the swap-back 2×2 of old and new wick and wax lots.
3263 A new soy wax bag feels softer: an unscented old-against-new twin pour.
3264 A new wick carton, smaller flames: physical lot checks and a timed flame log.
3265 A new oil order smells slightly different: a go/no-go gate scaled to the rupees at stake.
3266 The oil's colour changed between orders: an in-wax colour test at day 1, 7 and 14.
3267 A new oil batch throws harder but soots: a mini wick re-bracket.
3268 The jar changed slightly, same capacity: an old-against-new measurement sheet.
3269 New jars a few millimetres wider: a within-delivery spread sample.
3270 Fine in winter, sweats in summer: a seasonal comparison log.
3271 More frosting in winter production: a slow-cool A/B.
3272 Rough tops in certain months: a pour-temperature bracket against a room log.
3273 Moved into an AC room: a cooling-zone audit and position test.
3274 1 kg to 10 kg, not the same candle: a test-against-production batch sheet.
3275 A 20 kg pot cools slowly: a pot cooling log and a pour-window plan.
3276 Different melting equipment: an equipment qualification run.
3277 One employee's candles are better: a shadow run and a work instruction.
3278 Percentages are not enough: the process fields to record, and why.
3279 A batch sheet that traces failures: the template and a worked trace.
3280 Scaling, random faults: a defect cross-tab by lot, operator, day and SKU.

If the batch is not weaker but faint from the start (strong cold, faint hot), the triage is the cold-strong, hot-faint hub. Jars that vary within a delivery are also covered, from the buying side, by the jar dimension-variation post.

The CSI principle
Compare the batches before you accuse the materials.
A raw material is a suspect only if your records show it changed between the batches, and the verdict comes from candles you kept, burned at matched age, not from memory.
"The formula didn't change. The bag, the bottle, the pack and the calendar did. Find out which before you buy anything."

Why trust this guide

CandleMakingSuppliesIndia sells the wax, oils, wicks and tools named here, and does not sell finished candles. This page still ranks our materials below your records and your calendar, tells you not to reorder oil or wax to solve a weaker batch, says that the Sandalwood 1 kg is no cheaper per gram than its 100 g, and that any working one-gram scale does the scale's job.

Every price and per-gram 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 and temperature wording is quoted from the product pages; where a page is silent in the text we captured, we say so. CSI publishes no lot or batch data, composition or reformulation notices, and nothing here implies that a CSI batch changed.

The suspect ranking, the diff-sheet rows, the side-by-side protocol and the 0–3 score are editorial judgement; the batch dates, candle counts and bag and bottle history are a worked example; the melt-pool times and depths are commonly cited rules of thumb. For lot numbers on your orders, bulk pricing, GST invoicing, and MSDS and IFRA documentation on request, message us on WhatsApp at +91 7397976926.

Frequently asked questions

Why does my candle batch smell weaker than last month with the same recipe?
In our judgement, most commonly because the batches differ in something the recipe doesn't record: the age at which each was judged, the load actually weighed, or the add and pour temperatures. Check those before suspecting the oil, the wick pack, the wax bag or the jar, in that order.
Can a new batch of soy wax change hot throw?
It is possible, but only a suspect if your records show a new bag went into the weaker batch. Test it with unscented twins from the old and new bag, same jar and wick. CSI publishes no lot data; ask on WhatsApp for the lot numbers on your orders.
How do I compare two candle batches fairly?
Keep two unburned candles from every batch. Burn one from each on separate evenings in the same closed room once the newer batch reaches the age at which you approved the older one, then repeat with the second pair. Log pool, flame and a blind 0–3 score.
Should I buy a fresh bottle of fragrance oil if my new candles are weaker?
Not yet. A new bottle can't show whether your old one changed, and it adds a third lot. Audit your own bottle's age, fullness and storage first, and put any new order through a proportional gate against a retained sample before production.
How long should I wait before judging a new candle batch?
At least as long as you waited for the batch you are comparing it with. Oil pages that state a cure say 48–72 hours for soy; many makers judge hot throw at day 7 and 14. Comparing day 5 with day 14 compares cure, not materials.
Does CSI tell customers when a product batch changes?
CSI publishes no lot or batch release data, composition or reformulation notices. You can ask on WhatsApp for the lot or batch numbers on your orders and record them on your batch sheet, so any future comparison starts from facts.
Before you reorder anything
Build the diff sheet, then burn two old against two new at matched age.
In our judgement, many weaker repeat batches are simply younger, lighter or poured differently. Check the record and the cure age, then oil stock, wick pack, wax bag and jar. The side-by-side uses candles you already have (₹922.57 of materials in the worked example). Ask us on WhatsApp for the lot numbers on your orders.

Editorial standards & sources
About this guide: the hub page for CSI's cluster on a formula that suddenly gives a different result (3261–3280): the short answer (audit records and cure age before raw materials), a ranked differential table labelled as judgement, the diff sheet as a lot-lane chart, a costed retained-candle side-by-side with a decision rule, a what-not-to-buy box, and a one-line map of every post in the cluster.

All in stock on 26 September 2026. Per gram = price ÷ grams; per wick or jar = pack price ÷ units; two decimals. Worked costs use the exact per-gram price, then round.

Non-price figures: load is a percentage of total candle weight (150 g at 8% = 12 g oil + 138 g wax; a 40-candle batch = 480 g oil + 5,520 g wax). Ceilings and temperatures are as stated on the product pages (Sandalwood up to 10% for soy, cure 48–72 hours; CSI 464 up to 10%, pour 80–90°C; 150 g jar hot pour up to 85°C) and are formulation limits, not regulatory limits. The batch dates, bag, bottle and pack history, and the basis slip are a worked example. Melt-pool times and depths are commonly cited rules of thumb. The suspect ranking and decision rules are editorial judgement. Costs exclude labour, freight, packaging and GST. Diwali 8 November 2026 is a calendar fact.
