I Want to Turn a Successful Test Candle into a Repeatable Commercial Product — What Specifications Should I Lock for Wax, Fragrance Oil, Fragrance Load, Wick, Jar, Dye, Temperatures, Cure Time and Burn Performance Before Scaling?
Share
Where do the numbers come from? Two places only: the product pages (CSI 464 pour 80–90°C and up to 10%; jar hot pour up to 85°C; oil 6–10%) and your own tests (the wick, the cure age, the dye dose, the internal diameters). Write which is which.
What happens when something changes? The sheet decides. A new lot of the same product gets an incoming check; a new load, wick, dye dose or jar batch gets a partial retest; a new wax, oil or jar SKU gets a full one.
How do I know the sheet is complete? The sheet test: someone pours two candles from the sheet alone, beside two you make your usual way. If they differ, something you do isn't written down. Worked example: ₹871.60 of materials.

How a good test candle drifts in production
In our judgement, much of the drift from a successful test candle is not a raw material going wrong. It is a detail that lived in the maker's hands and never reached the paper: the way the wick was centred, how long the oil was stirred, which of two identical-looking jars was used, what "8%" meant, how old the candle was when it was sniffed. At a few candles a week the maker supplies those details from memory. At production volume, or with a second person, they vary. The pattern table shows the usual suspects, most common first; the ranking is our judgement, not measured frequency.
| # | Pattern | Unlocked field most likely responsible | Rules it in | Rules it out |
|---|---|---|---|---|
| 1 | Scent weaker or sweating more than the test | Load basis: "8%" computed a different way | Your notes say "12 g per 150 g of wax" rather than "per 150 g candle" | Weighed oil and wax match the sheet |
| 2 | Burn differs: tunnelling or a hotter jar | Wick centring or a jar batch with a different internal diameter | Wick position or measured diameters differ from the test | Same measurements, still different |
| 3 | Weak throw in early sales, fine later | Minimum cure age not written | Complaints came from the youngest candles | Same cure age as the test |
| 4 | Rough tops or wet spots that the test didn't have | Pour temperature or cooling not written | Batch sheets show different readings or rooms | Same readings and room |
| 5 | Colour differs batch to batch | Dye dose written as "a few chips" | No weighed dose on the sheet | Weighed dose, still different (then check the dye lot) |
| 6 | Changes after a restock | A lot or a product substitution | New lot or a different size or listing from the test | Same lot as the test |
Row 1 deserves a number because it is the easiest to get wrong and the least visible. Adding 12 g of oil to 150 g of wax gives a 162 g candle at 7.41% of total weight, not 8%; the other way round, 8% of total weight is 8.70% of the wax weight. Neither is wrong as a method; what goes wrong is a sheet that says "8%" without saying which, read by two people two ways. The basis conversion is the load-basis hub. The documentation side for the fragrance itself, a formula card for blends, is the formula-documentation post; this page covers the whole candle.
The specification sheet
Below is the worked-example sheet for a 150 g Chocolate Fudge candle. The third column is the discipline that makes the sheet trustworthy: every value says where it came from. Where a CSI page states a figure, the sheet quotes it; where no page does (the add temperature, the cure age, the dye dose, the internal diameter), the sheet records the result of your own test and the date of that test. Tolerances are yours to set; the examples are judgement.
| Field | Locked value | Source | Tolerance (example) |
|---|---|---|---|
| Wax | Luxury Soy Wax CSI 464 (flakes); lot recorded per bag | Product listing | No substitution |
| Fragrance oil | Chocolate Fudge Fragrance Oil (CSI listing name); any in-stock size; lot recorded; sealed retained sample per lot | Product listing | No substitution |
| Load and basis | 8% of total candle weight: 12 g oil + 138 g wax per 150 g candle | Your test, within both pages' 10% | Oil ±0.2 g per candle (or per batch equivalent) |
| Ceiling check | Oil page 6–10%; CSI 464 up to 10% → 10% governs (15 g per candle); cautious reading 9.09% of total | Both pages | Never exceeded |
| Wick | Eco C1 (the rung that won your bracket); centred with a device; wick lot recorded | Your bracket test, dated | Centred within a few mm at the set |
| Jar | Clear Glass Jar with Golden Lid (150 gram); internal diameter measured at top, middle and base; fill line marked | Listing + your measurements | Diameters within your limit, measured per carton |
| Fill | 150 g total to the marked line; headspace measured to the lid | Your test pour | ±2 g (example) |
| Dye | Brown Candle Dye Chips at your weighed dose per kg of wax; lot recorded | Your colour test | Weighed, not counted |
| Temperatures | Oil added at your recorded figure; pour 80–85°C | CSI 464 page: pour 80–90°C; jar page: up to 85°C | Read with a checked thermometer every batch |
| Stir | Your time and method | Your test (no CSI 464 figure) | Same tool, same time |
| Cooling | Room and spacing you used for the test | Your test | No draughts; same room |
| Minimum cure | The age at which your throw test passed | Your test (neither page states a cure) | No sale before it |
| Burn acceptance | Full pool within your target; pool depth; flame; no soot; jar temperature by non-contact thermometer through the final third; burn-down to about 1 cm | Your pass lines, dated | Every QC candle passes |
| Retained samples | One candle per batch; sealed oil sample per lot | Your procedure | Kept for your shelf-life of stock |
| Care line | Your wording, including trimming (the Candle Wick Trimmer page says "Trim your wick to 1/4 inch before every burn") | Your label | Same on every unit |
Three fields repay a closer look. The jar is a SKU plus measurements. The listing gives an outer diameter of 7 cm and a base of about 6.5 cm; your wick was chosen for the inside. A difference that looks small matters: at an internal diameter of 7.0 cm the pool's surface is 38.48 cm², at 6.6 cm it is 34.21 cm², so the wider jar has 12.5% more pool to fill with the same wick (worked example; measure your own). How much a few millimetres can change is the few-millimetres post, and what must match when you switch jar supplier is the jar-switch measurements post. The oil is a product and a lot, not a bottle. Chocolate Fudge's 100 g is out of stock on 26 September 2026; a sheet that specified "100 g bottle" would already be unbuyable, while one that names the oil and records the lot can be filled from the 50 g, 500 g or 1000 g at the same ₹3.96 per gram. The cure is your number. Chocolate Fudge's page and CSI 464's page state no cure time in the text we captured; the 25 oil pages that do state one say 48–72 hours for soy, and many makers judge throw at day 7 or later. Your minimum is the age at which your candle passed, not a figure borrowed from another oil.
Change control: which retests each change triggers
The second half of the specification is the rule for changing it. Decide it now, while nothing is urgent, so that a supplier stock-out or a cheaper jar in six months does not become a quick substitution nobody tested. The table sets the minimum retest for each kind of change; the scope is our judgement, built on how the fields interact.
| Change | Level | Minimum retest | Why |
|---|---|---|---|
| New lot of the same wax, oil, wick or dye | Incoming | One test candle against a retained candle; smell strip for oil; colour swatch for dye | Same product, possible lot difference |
| Different bottle or bag size, same product | Incoming | Lot check only | Size doesn't change the material |
| New jar batch, same SKU | Partial if measurements differ | Measure internal diameters; outside your limit → one-step wick check and a burn-down | Glass varies between batches |
| Load, within both ceilings | Partial | Throw at the cure minimum, wick check one step either side, sweat cycling, burn-down | Load moves the wick and the sweat margin |
| Dye dose or colour | Partial | Colour swatch, one burn-down | Heavy dye can affect the burn (tendency) |
| Stir method or equipment (e.g. a melter) | Partial | First, middle and last candles compared blind | Mixing reach changes with scale |
| Minimum cure shortened | Partial | Throw retest at the new age | The spec's throw pass was at the old age |
| Wick size or type | Full | Burn-down with final third, soot, throw at 1 h and 3 h | Everything in the burn follows the wick |
| Fragrance oil product or supplier | Full | Colour, sweat, wick bracket, throw, burn-down | Similar smell ≠ similar burn |
| Wax product | Full | Everything, including temperatures and cure | New ceiling, temperatures, wick draw, adhesion |
| Jar SKU | Full | Fill weight, wick bracket, final-third heat, lid fit | New geometry and glass |
| Temperature outside the pages' window | Not allowed | — | Beyond the stated figures |
Four of the full-retest rows have their own posts in this series and the sibling ones: a wax change is the wax-change interaction map; an oil from a new supplier that smells the same is the equal-smell, unequal-burn post and, on the formulation side, the minimum retest set for a new composition; a jar SKU change is the jar-change retest post. Two rows are commonly underestimated. A shorter cure looks like a scheduling change, not a formula change, but the throw pass on your sheet was earned at the old age. A melter or a new stirring method changes nothing on the ingredient list and can still change every candle it makes; the scale-side controls are the control plan by scale.
The sheet test
The last test before you call the sheet locked checks the sheet, not the candle. Someone who was not part of the development, or you working strictly from the paper with no memory allowed, pours two candles from the sheet alone. You pour two the way you normally do, from the same materials on the same day. All four are compared with a retained test candle that is at least as old. Worked example: 48 g of Chocolate Fudge and 552 g of CSI 464 across the four.
| Sheet candles (S) | Your candles (Y) | Meaning | Action |
|---|---|---|---|
| Match the retained candle | Match the retained candle | The sheet is complete | Lock version 1 |
| Differ | Match | Something you do isn't written | Find it in the batch-sheet comparison; add the line; repeat S |
| Match | Differ | You have drifted from your own recipe | Follow the sheet; check your habits |
| Differ | Differ, the same way | Materials or conditions changed since the test | Lot check against retained samples; room and season |
The four candles cost ₹871.60 in materials at ₹217.90 each (₹47.58 of oil at the 50 g price, ₹70.02 of wax, ₹94.40 for the jar and ₹5.90 for the wick; the dye is left out because the listing states no pack weight), excluding labour, freight, packaging and GST. A 50 g bottle leaves 2 g. It is one of the cheapest tests in the scale-up, and the one that tests your paperwork.
What not to buy while you lock it
We sell the materials on this sheet, and a locked spec means you will buy the same four things from us repeatedly, which suits us. It also means you should hold us to the same standard as anyone else: if a delivery doesn't match the sheet, the sheet says run the check before production, and tell us.
The materials named in the worked-example sheet
Four items: the wax, the jar, the dye and the oil the sheet names. Chosen on page statements, price and stock on 26 September 2026; CSI publishes no burn, throw or colour-stability data, so nothing is ranked on performance. The wick in the example is an Eco C1 (₹5.90 a wick), standing in for whichever rung won your bracket.

CandleMakingSuppliesIndia, based in Pune, sells the wax, jar, dye, wick and oil named here and does not sell finished candles. This page still tells you that bag and bottle sizes are not specifications, that our Brown Dye Chips listing carries the Black chips' text, that our jar listing contradicts itself on shape, and that a delivery from us that doesn't match your sheet should be checked like anyone else's.
Every price and per-unit figure was verified on CSI's live store on 26 September 2026; stock is checked per size and the out-of-stock Chocolate Fudge 100 g is flagged. Ceiling, temperature, jar and vanillin wording is quoted from the product pages; where a page is silent in the text we captured (the cure time on the oil and wax pages, the jar's internal diameter, the dye's pack weight and dose), we say so.
