My Candles Have Perfect Glass Adhesion in My Workshop but Develop Wet Spots After Courier Delivery — Are Temperature Cycles Causing the Wax to Separate from the Glass?
Aktie
Has the wax become wet? Almost certainly not. A wet spot is commonly an air gap where wax has separated from the glass; through clear glass it looks dark and glossy.
Should I change wax? Not until a bench cycle shows a best-practice pour still fails in your wax and a second wax passes in the same jar, oil and load — on two rounds.
What does testing cost? ₹0 with your own stock. From scratch, ten Clear 150 g jars with CSI 464, British Rose, wicks and IPA spray come to ₹2,843.40. See the kit.
What the patches most likely are, and the one test to run first
A candle that leaves your workshop with clean glass and arrives with dark, wet-looking patches has almost certainly not become wet. The patches are commonly described as places where the wax has separated from the glass and left a thin film of air. Through clear glass, that air gap reads as a darker, glossy or mottled patch, which is why customers mistake it for oil or moisture. Nothing has leaked; the contact between wax and glass has been lost over part of the wall.
Temperature change is the usual suspect, and it is a reasonable one. Wax and glass are commonly described as expanding and contracting by different amounts as they warm and cool, and soy wax is commonly described as still settling and crystallising for days after it sets. A sealed carton that sits in a warm van by day and a cooler hub by night puts the jar through exactly that kind of change, sometimes more than once. But "the courier did it" is a hypothesis, not a finding. The same candle might have spotted on your own shelf by the same day, because some wax pulls away a week after pouring whatever happens to it — and that is a different problem with a different fix.
So the single cheapest test is a split batch. From one pour, keep three candles at home on the shelf where your stock normally sits, and send three on your real courier route — to a friend, a relative or your own second address — with a cheap min/max thermometer inside the carton. Photograph all six through the glass on the same days. If the home candles spot too, the courier is not the cause, and the fix lives in your pour and cure. If only the travelled candles spot, temperature cycling is the trigger and the rest of this page is about how to measure it, reproduce it on a bench and decide what — if anything — to change.
| Home candles (A) | Travelled candles (B) | What it means | Next step |
|---|---|---|---|
| Clean | Clean | This shipment was unlucky or the route has changed | Repeat once on the route that complained; log temperature |
| Clean | Spotted | Temperature change in transit is the trigger | Log the route, build a bench cycle, test fixes against it |
| Spotted by the same day | Spotted | Time, not transit — the wax is pulling away on its own | Go back to pour, glass and cooling (late-appearing patches) |
| Spotted | Clean | Something at home is harsher than the route (AC, a window, a cold shelf) | Check where stock is stored (the AC-vent post) |
| Mixed within each arm | Mixed | Batch-to-batch or jar-to-jar variation is bigger than the courier effect | Number jars and record batch position (outer vs centre jars) |
Why temperature change can pull wax away from glass
In general candle-making practice, glass adhesion is described as a fragile contact rather than a glue. When hot wax is poured into a jar, it wets the glass; as it cools it solidifies and contracts. Where it stays in contact, the glass looks clear and even. Where the shrinking wax loses that contact, a gap forms. Makers commonly see more of this when the wax cools quickly against cold glass, when glass is not clean, or when the cooling is uneven around the jar. Those are pour-day causes, and the other sections of this series cover them.
Courier delivery adds a second set of causes after the candle has set. A warm phase can soften the outer skin of the wax slightly and make it expand; a cool phase makes it contract again. Glass changes size too, but commonly by a different amount and at a different speed, and the two surfaces do not have to move together. Each swing is a small mechanical tug on a contact that may already be weak in places. Makers commonly report that a patch, once it starts, can spread rather than heal. We do not publish contraction figures, expansion coefficients or failure rates for any CSI wax or jar, and we will not quote any as fact here — this page is about measuring what your route does to your candle.
Two practical consequences follow. First, the size of the swing matters more than the average temperature: a carton that goes from a cool hub to a hot afternoon van and back has been cycled harder than one that stays warm all day. The 25°C versus 35°C post and the AC-room-to-summer post take the size of the swing apart. Second, the number of swings may matter: a three-day delivery across zones is several cycles, not one. Repeated heating and cooling sets up the cycle-count test that shows whether spots grow with each cycle or appear once and stop.
The diagnosis ladder for delivered candles
The full series ladder runs from "is it really a wet spot?" through glass cleanliness, glass and pour temperature, cooling, storage and courier cycling, fragrance and dye, jar glass and finally the wax itself. For a candle that is clean at dispatch, the first four rungs have already partly cleared themselves — a candle that looked perfect when it left was at least poured onto clean enough glass at a workable temperature. But only partly: a marginal pour can look perfect and still fail at the first warm afternoon. That is why the ladder below starts with the split batch and then goes back up the process before it reaches materials.
| Rung | Suspect | Single test | Cost |
|---|---|---|---|
| 1 | Is it transit at all? | Split batch: 3 home, 3 shipped, same pour, same photo days | Courier only (example ₹240.00 for out and back) |
| 2 | How hard is the route? | Min/max thermometer or data logger inside a parcel on the real route | Thermometer (non-CSI, your quote) |
| 3 | Can a bench cycle reproduce it? | Warm/room cycles on 3 jars from the same pour (example settings below) | ₹0 beyond the jars |
| 4 | Is the pour marginal? | Bench cycle on jars poured with your best-practice jar prep and cooling vs your normal | Jars + wax |
| 5 | Is it the packaging? | Insulated vs normal carton on the same route | Packing material (your quote) |
| 6 | Is it this oil or load? | Same cycle, unscented vs scented, or 6% vs 8% | Wax + oil |
| 7 | Is it the wax? | Same cycle, second CSI wax in the same jar, same oil and load | One 500 g or 1 kg bag |
Rung 4 is the one most makers skip. A pour that is only just good enough on the day — glass slightly cold, wax at the bottom of the wax page's range, candles cooled near a draught — can pass inspection at dispatch and fail at the first warm-cool swing, where a pour with better margins does not. The bench cycle is what lets you see that difference without shipping anything. Cooling under the AC and winter-only patches cover the two pour-day conditions most often behind a marginal pour in Indian workshops.
The three-arm test: home, courier and bench
Here is the full version of the split batch, using the series default candle: 150 g in CSI's Clear Glass Jar with Golden Lid (150 gram) at 8%, which is 12 g of oil and 138 g of wax per jar. The example uses Luxury Soy Wax CSI 464 and British Rose, but the method does not depend on either — if you already make a candle, use your own wax, oil, wick and jar from the same lots for every arm. CSI 464's page gives an 80–90°C melt/pour range and the Clear 150 g jar's page states it is safe for hot pour up to 85°C, so in this jar the CSI 464 pour stays at 80–85°C. Pour all ten jars in one session from one melted batch.
| Checkpoint | Arm A (home) | Arm B (courier) | Arm C (bench) | Reference jar 10 |
|---|---|---|---|---|
| Pour day | Photo | Photo | Photo | Photo |
| 48 hours | Photo + score | Photo + score | Photo + score | Photo |
| 7 days (example dispatch age) | Photo + score | Packed and sent | Cycle starts | Photo |
| On return / after last cycle | Photo + score | Photo + score + route log | Photo + score | Photo |
| 30 days | Photo + score | Photo + score | Photo + score | Photo + score |
Three jars per arm is a screen, not a verdict. It is enough to see a large, consistent difference — all three travelled jars spotted, none of the home jars — and not enough to decide a small one. If the screen is unclear, the cheapest next step is more jars in the arms that matter, not a new material. The simple temperature-cycle test builds a fuller bench protocol, and testing across temperatures before pan-India approval shows how many conditions and jars a launch decision needs.
Arm C: a bench cycle you can repeat
Shipping candles is slow and every route is different, so once you know a route spots candles you want a bench cycle that reproduces it on demand. The point of a bench cycle is not to simulate India; it is to give you a repeatable stress that sorts a good pour from a marginal one, and that you can run again every time you change something. Its settings must come from your route log. Until you have one, use clearly labelled example settings and treat every result as provisional.
| Setting | Example value | Why | Replace with |
|---|---|---|---|
| Warm phase | A closed room, cupboard or car measured at about 38–40°C, 8 hours | Mimics a warm daytime van or hub | Your parcel log's high reading and how long it lasted |
| Room phase | Your normal workshop shelf, 16 hours | Lets the jar return to the temperature it is sold at | Your logged overnight low |
| Number of cycles | 3 to 5 | Delivery often spans several days | Days in transit on your slowest route |
| Packing | The jar inside your normal carton | Cartons slow and soften every swing | Exactly how you ship |
| Measurement | Min/max thermometer beside the jars (not the Pen Thermometer — that measures wax) | So the setting is a reading, not a guess | A logger if you can borrow one |
| Limits | Never near a melting range: CSI 468's page states 50–53°C, so warm phases stay well below it | A cycle is a stress test, not a melt test | Your own lower limit |
Notice what the bench cycle does not do. It does not tell you that your candle "survives" a temperature — we make no such claim for any CSI wax and you should not make one for your candle. It tells you whether Arm C spots like Arm B. If it does, you have a cheap, repeatable stand-in for your courier and every fix on the ladder can be tested against it in a week instead of a fortnight of parcels. If Arm B spots and Arm C does not, your bench is too gentle — move the warm phase towards your logged high, or add cycles, and try again.
The scoring sheet: your house scale
Score every jar the same way at every checkpoint. The example scale below grades the share of visible glass showing patches, estimated with a printed grid or a marked acetate sleeve wrapped round the jar. It is an example of a house standard, not a standard anyone else uses. If you prefer simple grades, keep the 0–4 column and drop the percentage — but pick one and keep it for every test that follows, because scores are only comparable with scores taken the same way.
| Jar | Arm | Batch position | 12 o'clock | 3 o'clock | 6 o'clock | 9 o'clock | Grade 0–4 | Notes |
|---|---|---|---|---|---|---|---|---|
| 1 | A home | e.g. edge | ___ | ___ | ___ | ___ | ___ | Shelf temperature today ___ |
| 4 | B courier | e.g. centre | ___ | ___ | ___ | ___ | ___ | Route high ___ low ___ days ___ |
| 7 | C bench | e.g. edge | ___ | ___ | ___ | ___ | ___ | Cycle no. ___ warm reading ___ |
| 10 | Reference | e.g. centre | ___ | ___ | ___ | ___ | ___ | Never moved |
Decide your pass line before the first score — for example, "no jar above grade 1 after delivery" or "no patch visible from arm's length". Both are house choices; how much variation is normal and what to record when comparing waxes help you set and defend yours. A rule written after the scores are in is not a rule.
The priced test kit
If you already make this candle, you need nothing from us for rungs 1–3: use your own jars, wax, oil and wick from the same lots. If you are setting up the test from scratch, here is the ten-jar kit for the series default candle, priced with listed, in-stock CSI packs. Grams use the CSI convention (oil = W × L) and a 5% pour-loss working allowance: 10 jars × 138 g wax = 1,380 g, plus 5% = 1,449.0 g; 10 × 12 g oil = 120 g, plus 5% = 126.0 g.
| Item | Need | Buy | Price | Skip if |
|---|---|---|---|---|
| Clear 150 g jar | 10 jars | 1 × pack of 10 | ₹944.00 | You already hold these jars from one lot |
| Luxury Soy Wax CSI 464 | 1,449.0 g | 1 × 1 kg + 1 × 500 g | ₹767.40 | You hold enough wax from your current lot (better) |
| British Rose | 126.0 g | 1 × 100 g + 2 × 15 g | ₹531.00 | You test your own production oil (better) |
| Eco Candle Wicks Thin C1 | 10 + 2 spare | 1 × pack of 20 (10-pack out of stock) | ₹118.00 | You use your own approved wick (you should) |
| Wick stickers | 10 | 1 × sheet of 40 | ₹100.00 | You hold stickers |
| Isopropyl Alcohol Spray | Jar wipe for every jar | 1 × 150 ml | ₹383.00 | You already clean jars with a residue-free method |
| Kit total, everything bought | ₹2,843.40 |
That is ₹246.04 of CSI materials per test jar, before the IPA spray. The leftover is small: 51 g of wax, 4 g of oil and 8 wicks. The Eco Thin C1 line is only the example wick; CSI publishes no wick size for this jar, so if you have not burn-tested a wick in it, that is a separate job and not part of an adhesion test. Courier, thermometer and packing are your own costs — the example courier figure on the ladder (₹120.00 each way) is a placeholder for your own rate.
What courier wet spots cost per acceptable candle
It helps to put a number on the problem before deciding how much effort to spend on it. The material cost of the series default candle at production rates is ₹70.02 of CSI 464 (at the 5 kg rate) + ₹36.82 of British Rose (at the 1 kg rate) + ₹5.90 example wick + ₹94.40 jar = ₹207.14, excluding labour, packaging, freight and GST. The rest of the sum below is a labelled example: replace every figure in italics with your own.
| Line | Example | Working |
|---|---|---|
| Candles shipped a month | 100 | Your figure |
| CSI materials per candle | ₹207.14 | ₹70.02 + ₹36.82 + ₹5.90 + ₹94.40 |
| Packaging + courier per parcel | ₹90.00 | Your quote |
| Share arriving visibly spotted | 12% | From your complaints and photos |
| Replacements sent | 12 | 100 × 12% |
| Cost of each replacement | ₹297.14 | materials + packaging and courier |
| Month's total cost | ₹33,279.37 | 100 × ₹297.14 + ₹3,565.65 |
| Cost per acceptable delivered candle | ₹332.79 | ₹33,279.37 ÷ 100 |
| Same with no spotted arrivals | ₹297.14 | materials + packaging and courier |
| What the spots cost per candle | ₹35.66 | difference |
In this example the spots add ₹35.66 to every acceptable candle — and that is before your time answering complaints, a lost repeat order or a poor review, which you can add as your own labelled line. If you discount spotted candles instead of replacing them, treat the discount as the cost and keep it in a separate row; the discounted-stock post shows both treatments. The point is not the example figure. It is that a few hundred rupees spent on a split-batch and bench test is small next to a recurring replacement line.
The decision rule: change the process, the packing or the wax
Apply it from the top and stop at the first line that is true. It is written so two people reading the same sheets reach the same decision.
| If this is true | It means | Do or buy |
|---|---|---|
| Home jars spot as much as travelled jars | Not transit — the pour or cure | Nothing new. Work the pour-day rungs (the process-diagnosis capstone) |
| Travelled and bench jars spot, home jars clean | Temperature cycling is the trigger | Nothing yet — rerun the bench cycle on a best-practice pour |
| Best-practice pour passes the bench cycle | The pour was marginal | Nothing. Write the better jar prep and cooling into your SOP |
| Best-practice pour still fails; insulated carton passes | The route is harsh; the candle is sound | Change the packing — your own packaging quote |
| Unscented or lower-load jars pass, scented 8% fails | Oil or load is part of it | Test 6% (the load post) before any wax |
| Everything fails except a second wax arm, on two rounds | The wax–jar pairing | One 5 kg bag of the winning wax, then wick and throw retests |
| Nothing passes anywhere | Clear glass on this route may need a different presentation | Consider a frosted jar for shipped SKUs (the frosted-jar post) |
Most lines end in a process change, not a purchase. That is deliberate: a candle that is clean on your shelf and spotted on arrival has proved it can adhere, so the first suspects are the margins of your pour and the harshness of the route. When a wax change does win, it re-opens wick, fragrance-load, cure and hot-throw validation, so price that in before switching. If you do switch to CSI 464 at production volume, its per-kilo price is ₹507.40 at 1, 5 and 10 kg — buy the 5 kg bag for convenience, not for a discount, and ask on WhatsApp about anything larger.

Four other hubs pick up where a rung on the ladder points. Wet spot or pulled away? owns what a wet spot is and how to tell it from real moisture. Winter glass, preheating and jar cleaning owns jar preparation and pour temperature. Fragrance, dye and jar supplier owns oils, dyes, glass and wax choice. Cosmetic reject cost and wax qualification owns the money and the purchase.
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. The easy answer for a wax seller is "switch to a wax with better adhesion". This page tells you that all three of our container soy waxes' pages make the same adhesion claim, that we publish no heat or cycle results for any of them, and that the first test needs nothing from us at all.

Non-price figures and assumptions: Load convention: fragrance load is a share of the finished candle (oil = W × L; wax = W × (1 − L)). Series default candle: 150 g in the Clear 150 g jar at 8% = 12 g oil + 138 g wax. Working practices: 3 jars per arm plus 1 reference, 5% pour loss, photo checkpoints at pour day, 48 hours, 7 days, after delivery/cycling and 30 days, 0–4 house scale. Example bench cycle: about 38–40°C for 8 hours then 16 hours at room, 3–5 cycles — replace with your route log. Example economics: 100 candles a month, ₹90.00 packaging and courier per parcel, 12% spotted — all placeholders. Per-candle cost uses the CSI 464 5 kg rate and the British Rose 1 kg rate. What CSI's product pages state (quoted, not CSI test results): Luxury Soy Wax Chunks — maximum fragrance load 13%, fragrance addition 80–90°C, pour 75–80°C in the spec table (the step list also shows 70–80°C), stir 2 minutes, cure at least 48 hours, ideally 1–2 weeks, and "excellent adhesion to glass and container surfaces"; Luxury Soy Wax CSI 464 — fragrance load up to 10%, an 80–90°C melt/pour range, "excellent glass adhesion", single-pour, low frosting; Premium Coconut Soy Wax CSI 468 — melting point 50–53°C, pour 58–60°C, fragrance load up to 13%, "formulated for excellent glass adhesion"; Natural Soy Pearl — no fragrance ceiling, temperature, cure or adhesion statement published. Clear Glass Jar with Golden Lid (150 gram) — fill approximately 150 g, "safe for hot pour up to 85°C". All three adhesion statements are the same claim, so they cannot rank the waxes; only a side-by-side test in your jar can. CSI publishes no adhesion, wet-spot, contraction or shrinkage data for any wax, oil, dye or jar, no glass thickness or internal diameter for any jar, no wick size for any jar, and no heat-survival or temperature-cycle results. There is no industry acceptance threshold for wet spots; every scale and pass line on this page is a labelled house standard. Wet-spot mechanisms are described as general candle-making knowledge. Material costs exclude labour, packaging, freight and GST. Diwali 2026 falls on Sunday 8 November.
