I Want to Build a Professional Candle Formula — How Should I Match Fragrance Oil, Wax, Fragrance Load, Wick, Vessel Diameter, Cure Time and Burn Testing?
Share
How do I set the load? Take the lower of the two published figures — your wax page's and your oil page's. Luxury Soy Wax Chunks state 8–13%; the Sandalwood page states up to 10% for soy wax. The card's load is therefore 10%: 15 g of oil and 135 g of wax in a 150 g candle.
What does the card cost to build? A six-jar wick bracket at ₹1,576.37 and fourteen days. What it costs to break is the same again, every time you change one input — which is exactly why the card has a version number.
What is the single most useful line on it? The conflict check. The 150 g jar states "Safe for hot pour up to 85°C"; CSI 464 states a pour of 80–90°C. Two correct pages, one incompatible pairing — and a card is where you catch it before a thousand jars are filled.
The formula card
One sheet, three blocks. The inputs are the seven decisions plus the two temperatures. The acceptance criteria are written before the pour and are what the card is measured against forever. The control block is the version number, the date, the signature and — the field most cards miss — the source of every number, so that in eight months you can tell which figures came off a product page and which ones you decided yourself.
| Field | Worked entry | Source of the figure |
|---|---|---|
| 1 · Vessel and diameter | Clear Glass Jar with Golden Lid (150 gram) · "Height 8cm, outer diameter 7cm", base "Approximately 6.5 cm", "150g fill capacity", "Safe for hot pour up to 85°C" | Product page, verbatim |
| 2 · Wax | Luxury Soy Wax Chunks, 135 g per candle, ₹0.5999/g at 10 kg pricing | Product page and live price |
| 3 · Fragrance oil | Sandalwood Fragrance Oil, 15 g per candle, ₹5.0268/g at 1 kg pricing | Product page and live price |
| 4 · Load, and the two figures it came from | 10% of the finished candle. Wax page states 8–13%; oil page states "Up to 10% for soy wax". Governing figure = the lower | Both product pages; the choice is ours and it is written down |
| 5 · Wick | Eco Candle Wicks Thick (C2), one per candle, ₹9.44 at 100. Chosen by bracket — the page states no diameter guidance | Our six-jar bracket, not a page |
| 6 · Cure | 14 days, lidded, in a closed carton at room temperature. Wax page: "minimum of 48 hours (ideally 1-2 weeks)". Oil page: 48–72 hours. We take the longest | Both pages; the 14-day choice is ours |
| 7 · Burn test | Two jars per batch, up to three hours per burn, one scent per session, closed room | Our protocol |
| 8 · Add temperature | 82–86°C, inside the page's stated 80–90°C and well below the oil's stated 203°C flash point. Stir two full minutes | Wax page band; the narrower working window is ours |
| 9 · Pour temperature | 74–78°C, inside the page's stated 70–80°C and below the jar's stated 85°C hot-pour limit | Wax page and jar page |
| Criterion A | Full melt pool reaching the glass all round in 2–3 hours | Written before the pour |
| Criterion B | No soot, no mushrooming, pool depth under about a centimetre | Written before the pour |
| Criterion C | Unlit control jar shows a clean surface and no colour shift at day 28 | Written before the pour |
| Criterion D | Cold throw at day 14 and hot throw at 30 and 120 minutes scored 1–5, at or above the incumbent | Written before the pour |
| Version | v1.0 · 14 September 2026 · signed | Control |
| Materials per candle | ₹262.73 — wax ₹80.99, oil ₹75.40, jar ₹94.40, wick ₹9.44, sticker ₹2.50 | Arithmetic from live prices |
| Voids this card | Any change to fields 1–5, or to the load. Cure and temperatures may be tightened within the stated bands without a new version; loosened, they cannot | Control |

The order you must decide them in
A formula is a dependency chain. Some decisions restrict many others; some restrict almost nothing. Deciding in the wrong order means discovering halfway through that your beautiful oil cannot be poured at the temperature your jar allows, or that the vessel you designed the label for needs a wick family you do not stock. The table below is the order, with what each step closes off.
| Order | Decision | What it constrains | What goes wrong if you decide it later |
|---|---|---|---|
| 1 | Vessel — diameter, fill weight, hot-pour limit | Pool area, wick family, candle size, price point, packaging | You qualify a recipe in one jar and re-qualify everything when the real jar arrives |
| 2 | Wax | The load ceiling, the add and pour temperatures, the set behaviour, the cure length | You choose a wax whose stated pour temperature is incompatible with the jar's stated limit |
| 3 | Fragrance oil | The second load figure, the discolouration risk, the flash-point margin, the price per candle | You fall in love with an oil whose stated load is below the one your recipe card already promises |
| 4 | Load | Grams of oil and wax, cost per candle, how hard the wick has to work | You set a load before you know which of the two published figures is lower, and overshoot it |
| 5 | Wick | Whether the pool ever reaches the glass; soot; pool depth | You pick a wick from a memory of a different jar and spend the bracket twice |
| 6 | Cure | When the candle may be judged, and how much stock sits in cartons | You judge at day 3, re-wick a candle that was correct, and ship a sooting one |
| 7 | Burn test | Nothing — it is the measurement, not an input | You run it without written criteria, and the result becomes whatever the room feels like that day |
The worked card, step by step
One candle, seven decisions, every number sourced. This is the same worked example the card above records, built in front of you so that you can substitute your own vessel and follow the same logic.
| Line | Per candle | Rate | Cost | × 6 (a bracket) | × 1,000 |
|---|---|---|---|---|---|
| Luxury Soy Wax Chunks | 135 g | ₹0.5999/g at 10 kg | ₹80.99 | ₹485.92 | 135 kg → ₹83,986 (14 × 10 kg) |
| Sandalwood Fragrance Oil | 15 g | ₹5.0268/g at 1 kg | ₹75.40 | ₹452.41 | 15 kg → ₹75,402 (15 × 1 kg) |
| 150 g golden-lid jar | 1 | ₹94.40 at pack of 10 | ₹94.40 | ₹566.40 | ₹94,400 |
| Eco Candle Wicks Thick (C2) | 1 | ₹9.44 at 100 | ₹9.44 | ₹56.64 | ₹9,440 |
| Candle Wick Sticker | 1 | ₹2.50 at 40 | ₹2.50 | ₹15 | ₹2,500 |

Where published numbers conflict
Nothing in this section is a fault in any product. It is what happens when specifications written independently meet in one candle — and it is the reason a card is a cross-check rather than a shopping list. Four conflicts come up repeatedly, and all four are resolved the same way: take the more conservative number and write down why.
| Conflict | The two published figures | Resolution | What goes on the card |
|---|---|---|---|
| Wax pour temperature vs jar hot-pour limit | CSI 464: "Pour Temperature 80°C – 90°C". The 150 g jars: "Safe for hot pour up to 85°C" | The vessel wins. Either pour at the bottom of the wax's band and stay under 85°C, or choose a wax whose stated band fits entirely — Chunks at 70–80°C, or CSI 468 at 58–60°C | "Pour 74–78°C · jar limit 85°C · wax band 70–80°C" |
| Wax load ceiling vs oil load figure | Chunks: "8% to 13%". Sandalwood: "Up to 10% for soy wax" | The lower figure governs, always | "Load 10% · wax 13% · oil 10% · governing = oil" |
| Oil flash point vs wax add temperature | Palo Santo: "Flashpoint: 93°C". Chunks: add at 80–90°C | Add at the bottom of the wax's band, log the actual reading, and read what a flash point does and does not tell you before deciding. Where a page publishes no flash point, write "not published — SDS requested" | "Add 82–86°C · oil FP 203°C (stated) · margin wide" |
| Cure figures that differ | Chunks: "minimum of 48 hours (ideally 1-2 weeks)". Most oil pages: "48–72 hours" for soy | Take the longest published figure and its upper bound. Standard practice for soy containers is 14–21 days | "Cure 14 days · wax ideally 1–2 weeks · oil 48–72 h" |
What voids a card, and what a re-test costs
Every change is legitimate; what is not legitimate is changing something and keeping the old card. The table prices each change at this card's own numbers, so the cost of a decision is visible at the moment you take it. A bracket here is six jars — ₹1,576.37 — and a two-jar confirmation is ₹525.46.
| Change | New version | What is now unproven | Re-test needed | Cost of re-proving |
|---|---|---|---|---|
| Same everything, new production batch | v1.0 unchanged | Nothing — but the batch record is new | Two jars from the batch, burned after cure | ₹525.46 |
| New fragrance oil, same wax, jar, wick, load | v2.0 | The load (the new oil's figure may be lower), the wick, the cure, the colour behaviour | Full bracket at two loads | ₹1,576.37 |
| Load changed by two points | v1.1 | The wick and the surface behaviour | Bracket at the new load, plus an unlit jar to day 28 | ₹1,576.37 |
| New wick size, everything else fixed | v1.2 | Pool time, soot, pool depth | Bracket, old wick against new | ₹1,576.37 |
| New wax | v3.0 | Everything except the jar — load ceiling, pour temperature, set behaviour, wick | Full bracket, and re-check the pour against the jar's stated limit | ₹1,576.37 plus a new wax pack |
| New jar diameter | v4.0 | Pool area, wick, fill weight, cost per candle, and the hot-pour limit | Full bracket in the new jar | ₹1,576.37 plus a jar pack |
| Cure shortened below the card's figure | Not a version — a deviation | All four acceptance criteria | Do not ship it as the same product | The batch |
Two things follow from reading that table honestly. First, a new oil is a bigger change than a new load, because it moves the governing figure, the colour risk and the flash-point margin all at once — which is why new scents deserve a staged qualification rather than a swap. Second, the cheapest possible change is no change: a stable card running for six months on the same materials is worth more than a slightly better candle you cannot reproduce. If you are qualifying a new scent at volume, the four-gate version of this is in how to test a new fragrance before a 1,000-candle batch.
From the card to a thousand candles
The last job of a formula card is arithmetic: multiply the per-candle grams by the month's volume, round up to listed packs, and you have an order. Below is this card at a thousand candles, with the two places the listed range runs out named plainly.
| Line | Needed | Ordered as | Cost | Note |
|---|---|---|---|---|
| Luxury Soy Wax Chunks | 135 kg (140.4 kg with a 4% allowance) | 14 × 10 kg at ₹5,999 | ₹83,986 | 10 kg is the largest listed pack; there is no 25 kg or 100 kg listing |
| Sandalwood Fragrance Oil | 15 kg | 15 × 1 kg at ₹5,026.80 | ₹75,402 | 1 kg is the largest listed fragrance pack; there is no 5 kg or 10 kg listing |
| Eco Candle Wicks Thick (C2) | 1,000 | 1 × 1000 at ₹9,440 | ₹9,440 | ₹9.44 each — flat from 10 wicks to 1,000 |
| 150 g golden-lid jars | 1,000 | 50 × pack of 20 at ₹1,888 | ₹94,400 | ₹94.40 each — flat between the pack of 10 and the pack of 20 |
| Candle wick stickers | 1,000 | 25 × 40-sticker sheets at ₹100 | ₹2,500 | The 100-sticker sheet is currently sold out |
| Total | ₹2,65,728 | ₹265.73 per candle against the card's ₹262.73 of consumed material — the difference is the wax allowance |
Two honest caveats before you place it. Those listed per-unit prices are the ceiling for these quantities: recurring monthly volumes and anything above the largest listed pack are quoted separately on WhatsApp, along with GST invoicing and the SDS or IFRA documentation you should be filing against the card — and we will not tell you in advance what that quote will be. And add a working-capital line: at 1,000 candles a month a fourteen-day cure means about ₹1,22,606.63 of finished stock sitting in cartons at any time, which is a number your cash flow needs even though no supplier invoices you for it.
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles, and the most useful thing we can tell a maker at the end of a hundred-post series is stop buying and start documenting. Nothing on this card requires a new product. It requires a sheet of paper, six test jars and a fortnight. We sell the wax and the oil, and we are telling you that the thing standing between a candle that worked once and a business is a version number.
Every price, dimension and specification here comes from live CSI stock in September 2026 and links to the product page, where current pricing and specification always take precedence. Loads, add and pour temperatures, hot-pour limits, flash points, vanillin figures, cure times and diameters are quoted only where the product page states them, and the blanks are named: the Chunks page states no melting point, the Eco Candle Wicks page states no diameter guidance, and no CSI oil page states a storage instruction or a shelf life. Stated loads are formulation guidance published per material — not regulatory limits and not interchangeable between waxes. Pool areas are calculated from stated diameters and describe the area a full pool can reach, not a burn result. The burn test, the bracket and the acceptance criteria are protocols for you to run; no pool time, throw score or pass rate on this page is a measurement we are reporting.

Figures verified September 2026: Card v1.0 = a 150 g candle at a 10% load (15 g oil + 135 g wax). Vessel — Clear Glass Jar with Golden Lid (150 gram), page states "Height 8cm, outer diameter 7cm", base diameter "Approximately 6.5 cm", "150g fill capacity" and "Safe for hot pour up to 85°C"; pack of 10 ₹944 and pack of 20 ₹1,888 (₹94.40 each). Wax — Luxury Soy Wax Chunks 500 g ₹299, 1 kg ₹599, 5 kg ₹2,995, 10 kg ₹5,999 (₹0.5999/g); page states "up to 13% fragrance load capacity", "Recommended fragrance load: 8% to 13% of total wax weight", "10% Recommended", "Recommended fragrance add temp 80-90°C", "Recommended pour temp 75-80°C" and "Pour at 70-80°C into your prepared containers with wicks in place", and "Allow candles to cure for a minimum of 48 hours (ideally 1-2 weeks) before performing burn tests"; the page states no melting point. Oil — Sandalwood Fragrance Oil 15 gm ₹93.22, 50 gm ₹271.40, 100 gm ₹502.68, 500 gm ₹2,513.40, 1 kg ₹5,026.80 (₹5.0268/g); page states "Up to 10% for soy wax" and "Up to 6% for paraffin wax" with cure 48–72 hours for soy, "Flashpoint 203°C", and "Vanillin content 0% - no discolouration, safe for white and neutral wax". Wick — Eco Candle Wicks Thin (C1) ₹59/10 to ₹5,900/1000 (₹5.90 each) and Thick (C2) ₹188.80/20 to ₹9,440/1000 (₹9.44 each), the 10-wick C2 pack currently sold out; the page states no diameter guidance, and C1/C2 appear only as variant names. Cotton Braided Wicks Ready Made ₹120/10 to ₹12,000/1000 (₹12 each), page states "engineered for large-diameter candles exceeding 8 cm" and a wick height of 10.16 cm. Eco Candle Wicks Loose page states "designed specifically for 2 inch diameters". Candle Wick Stickers 40 for ₹100 (₹2.50 each); the 100-sticker sheet is currently sold out. Other waxes cross-referenced: Luxury Soy Wax CSI 464 1 kg ₹507.40, 10 kg ₹5,074, page states "Fragrance Load Up to 10%", "Melting Point 80°C – 90°C" and "Pour Temperature 80°C – 90°C"; Premium Coconut Soy CSI 468 1 kg ₹650, 10 kg ₹6,370, page states "Fragrance Load Up to 13%", "Melting Point 50°C – 53°C" and "Pour Temperature 58°C – 60°C". Palo Santo page states "Flashpoint: 93°C". Card arithmetic: wax 135 g × ₹0.5999 = ₹80.99; oil 15 g × ₹5.0268 = ₹75.40; jar ₹94.40; wick ₹9.44; sticker ₹2.50; total ₹262.73 per candle. A six-jar bracket is 6 × ₹262.73 = ₹1,576.37 and a two-jar confirmation 2 × ₹262.73 = ₹525.46; the C1-to-C2 wick difference across six jars is ₹21.24. One thousand candles: 135 kg of wax (140.4 kg with a 4% planning allowance) bought as 14 × 10 kg = ₹83,986 for 140 kg; 15 kg of oil bought as 15 × 1 kg = ₹75,402; 1,000 C2 wicks ₹9,440; 1,000 jars ₹94,400; 1,000 stickers ₹2,500; total ₹2,65,728, or ₹265.73 per candle. Fourteen days of cure on 1,000 candles = ₹262.73 × 1,000 × 14 ÷ 30 = ₹1,22,606.63 of stock held. Pool areas are calculated as π × (stated diameter ÷ 2)²: 6.5 cm = 33.18 cm², 7 cm = 38.48 cm², 6 cm = 28.27 cm². Load is measured as a share of the finished candle; where the Chunks page words its range as a share of total wax weight, the two conventions differ by under a gram at these percentages on a 150 g candle. Flash-point coverage across the 107 CSI fragrance pages: 18 state a measured value, 32 state only "Flash point > 93°C (suitable for alcohol-based products)" — a threshold for alcohol-based products, not a measurement — and 56 state none; no page states a storage instruction, storage temperature, expiry or shelf life, and no page publishes an IFRA certificate, amendment, category number or date. Cure of 14–21 days for soy containers reflects standard practice. No 25 kg or 100 kg wax pack and no 5 kg or 10 kg fragrance oil pack is listed; listed per-unit prices are the ceiling for those quantities, and larger or recurring volumes are quoted on WhatsApp. Prices and availability change — the linked product pages are always authoritative.
