CSI Jar & Container Guides · Glass Safety
Before a new container goes on sale, a small brand needs its own evidence, not a listing's wording. Here is the minimum: eight tests, three burn-downs, one signed file, and labels that warn rather than promise, costed and scheduled.
₹4,625.20
the full worked programme for a new 150 g jar, tools included · CSI live pricing, September 2026
Quick answers — read this first
What is the minimum before selling a new container? Eight tests and one file: a paper check with written supplier answers; incoming inspection of every jar; measurement and fill weight; a logged pour-and-cool test inside the stated limits; at least three full burn-downs to the stop line with the final third watched; a finish test if the jar is coated or frosted; a lid and transit test; and labels with safety warnings. Record everything in a container file and sign it off.How many jars and how long? Worked example: 20 jars inspected, 3 water-filled, 10 poured (3 burn-downs, 3 reserves, 2 couriered, 1 unlit control, 1 retained sample), in about four weeks including cure. Diwali, 8 November 2026, is 43 days away: tight but possible if you start now.
What does it cost? With the Clear 150 g jar and CSI 464: ₹4,625.20 including thermometer, scale and safety stickers; ₹3,917.20 if you already own the tools. Spread over your first 100 candles, ₹46.25 each.
Does a "safe for hot pour" listing let me skip it? No. Only seven CSI listings state a figure ("hot-pour up to 85°C"), it is page wording rather than test data, and CSI publishes no burn-down or breakage data. The programme is how you get your own evidence.
The short answer
The list: paper check, inspection, measurement, pour-and-cool, burn-down ×3 (final third), finish test if coated, lid and transit, labels and warnings.
The records: one container file per jar: listing wording and date, supplier answers, batch, every log, photos, label proof, sign-off, and the triggers for a retest.
The numbers: 20 jars, 10 poured, 3 burned down plus 3 reserves, about four weeks; ₹4,625.20 with tools in the worked example.
The rule: never call the jar "safe" on your label because a listing did; state warnings, not promises.
In this guide
The programme laid out against the calendar. The black bars are the work; the grey bars are waiting (cure) or running in parallel (transit); the dashed bar is delivery, which you should confirm rather than assume. The burn-downs take the longest, and they cannot be rushed: a customer's candle is burned in sessions, and so is yours.

Straight answer
What jar safety tests should a small candle brand complete before buying and selling a new container commercially?
Eight, recorded in one file. 1. Paper check: quote the listing's heat, capacity and finish wording with the date, and get the supplier's answers in writing on glass type, any stated pour figure, any coating, and batch. 2. Incoming inspection: every jar, rejecting any chip, crack or sharp edge. 3. Measurement: inside diameter, height, rim for the lid, water-fill to your fill line, and a weighed fill. 4. Pour-and-cool: pour inside the lower of the jar's and the wax's stated limits into warmed jars, cool slowly, log every jar. 5. Burn-downs: at least three candles of your final formula and approved wick, in normal sessions, to about 1 cm of wax, watching the final third for flame height, soot, glass heat and any flame near the glass. 6. Finish: for frosted, painted or coated jars, grade the finish against an unlit control. 7. Lid and transit: lid fit across the batch and clearance above the wick; two finished candles couriered and inspected on arrival. 8. Labels: safety warnings on every candle, net quantity checked against current Legal Metrology requirements, and nothing that calls the jar "safe". Then sign it off, and write down what would make you run it again. Worked example: 20 jars, about four weeks, ₹4,625.20 with tools.
One line: eight tests, three burn-downs minimum, one signed container file, and no claim on your label that your own tests did not earn.
Twenty jars run the whole programme. A pack of 20 Clear Glass Jars with Golden Lid (150 gram) is ₹1,888.00 (₹94.40 each, in stock on 26 September 2026): 20 inspected and lid-fitted, 3 water-filled, 10 poured, with the rest held for replacements.

The eight tests, what each proves, and the pass line
A listing tells you what a jar is supposed to be. The programme tells you what it is in your hands, with your wax, your wick and your customers.
This is the capstone of the glass-safety cluster: the minimum list, with the detailed method for each test in its own guide. The counts are our judgement of a sensible minimum for a small brand, not a standard; a brand selling thousands of units, or importing, should do more (the import approval guide).
Minimum programme for a new container · our judgement, not an industry standard
Test, minimum count, pass line, and where the method lives
| Test | What it proves | Minimum | Pass line | Method |
|---|---|---|---|---|
| 1. Paper check | What is claimed, and what is not | Listing wording dated; written supplier answers | Every claim you rely on is quoted and dated; unanswered questions are noted as unknown | Suitability hub, supplier claims |
| 2. Incoming inspection | No flawed glass enters production | Every jar | No chip, crack, sharp edge, deep scratch or open bubble | Reject policy |
| 3. Measurement and fill | Inside diameter, fill line, net quantity | 3 jars water-filled; inside diameter at 2 to 3 heights | Fill weight weighed, not assumed; headspace clears the lid | Fill-weight hub, external vs internal diameter |
| 4. Pour-and-cool | The jar survives your production pour | 10 jars, logged | No cracks; pour inside the lower of the two stated limits | Cooling cracks |
| 5. Burn-downs | The whole candle life, final third included | 3 candles to the stop line, 3 in reserve | Full pool without a flame reaching the glass; no crack; no soot build-up that points to an oversized flame; stops cleanly at about 1 cm | Pre-order heat test, final third |
| 6. Finish (if coated) | Frost, paint or coating survives repeated heat | Burn-down jars graded against 1 unlit control | No change visible at arm's length, felt or smelled | Frosted-coating test |
| 7. Lid and transit | Lid fits across the batch; candles arrive intact | Lid on all 20 jars; 2 candles couriered | Lids sit flat without catching; clearance above the wick; no chips or cracks on arrival | Lid tolerance, transit packaging |
| 8. Labels and warnings | Customers know how to burn it | Label proof on the retained sample | Warnings present; net quantity checked; no "safe" or "certified" claim | This page |
Three burn-downs is a floor, not a target. One burn-down is an anecdote; two that disagree leave you guessing; three that agree give you a pattern you can defend. If any one fails for a reason that is not the wick or a draught, the jar has not passed, and a reserve burn-down does not overrule it.
Mistake: treating the supplier's "heat resistant" wording, or a numeric figure like "hot-pour up to 85°C", as test 5. What actually happens: a pour limit says nothing about the final third, a drifting wick, or your fragrance load. CSI publishes no thermal-shock, burn-down or breakage data for its jars, and a listing figure is page wording, not your evidence. Fix: quote the wording in test 1, respect it in test 4, and run test 5 anyway.
Running it in four weeks
The diagram shows the calendar; here is the order of work. It assumes your wick and formula are already chosen for this jar. If they are not, bracket the wick first, and add a week or two.
1
Days 0 to 2: paper check and supplier questionsScreenshot the listing and note the date. Quote its heat, capacity, dimension and finish wording exactly. Ask the supplier in writing: glass type, any stated pour temperature, whether a finish is a coating, the batch or lot you will receive, and whether future orders will match. For CSI jars, ask us on WhatsApp; we will tell you what we know and what we don't.
2
Days 4 to 5: inspect, measure, fit lidsAll 20 jars through the 30-second inspection. Measure the inside diameter at two or three heights, the height and the rim; water-fill three to your fill line; fit a lid to every jar. Record rejects by carton.
3
Days 5 to 6: pour ten, loggedYour final formula; the jar warmed evenly; the wax measured in the pitcher inside the lower of the two stated limits (CSI 464 in a jar stating 85°C: 80°C to 85°C); cooling on wood, no fans. Log jar number, pour temperature, surface and airflow. Weigh each finished candle for the net-quantity record.
4
Cure, then label the tenCure as you normally would for your wax. Put your draft label and warning sticker on every poured candle now, so the burn-downs also test label adhesion near a warm jar.
5
Burn three to the stop lineNormal sessions, up to about four hours each (common candle-care guidance), full cool-downs, wick trimmed before each relight, never unattended, on a heat-resistant surface away from draughts. Log melt pool, flame height, soot, and, in the final third, glass temperature read at the same spots each session with a non-contact infrared thermometer if you have one; never judge it by hand or by lifting a lit candle. Stop at about 1 cm of wax. Grade any finish against the unlit control.
6
In parallel: courier twoPack two cured candles exactly as you will ship them and send them to a friend in another city, or to yourself. Inspect on arrival: rims, lids, cracks, labels, wax surface.
7
Close the file and sign it offEvery log, photo and answer in one folder; the retained sample labelled and kept; a single page stating the jar, the batch, the formula, the results, the date and who approved it, plus the retest triggers below. Only then order production quantity.
Why ten poured, not three
Three burn-downs are the heart of it, but three reserves cover a burn that fails for a non-jar reason (a drifted wick, a draught, an untrimmed wick); two go through the post; one stays unlit as the colour and finish control; one becomes the retained sample in your file. Ten jars from a pack of 20 leaves ten for inspection rejects and replacements.The container file: what to keep
If you cannot show it, you did not test it.
A small brand does not need a laboratory, but it does need to be able to answer three questions months later: what did we test, on which batch, and what did we see? The container file does that. Keep it as a folder on your phone or laptop, with a printed summary page in the workshop.
Container file contents · one file per container, per supplier
What to keep, and why you will be glad you did
| Record | What goes in it | Why it matters later |
|---|---|---|
| Listing snapshot | Screenshot, date, quoted heat, capacity and finish wording | Listings change; you need what it said when you approved it |
| Supplier answers | Written replies on glass type, pour figure, coating, batch | Shows what you were told, and what was never confirmed |
| Batch record | Delivery date, lot or batch if given, carton marks | Links every later problem to a batch |
| Inspection log | Rejects per carton, photos | Separates transit damage from workshop damage |
| Measurements | Inside diameter at 2 to 3 heights, height, rim, fill line, water-fill, weighed fill | Your wick, fill weight and label all rest on these |
| Pour-and-cool log | Jar number, pitcher temperature, surface, airflow, cracks | The baseline if breakage ever starts |
| Burn-down logs | Sessions, pool, flame, soot, glass warmth in the final third, stop line, photos | The evidence behind your approval |
| Finish grades | Scores and photos against the control (coated jars) | Shows the finish was checked, not assumed |
| Lid and transit results | Lid fit across the batch, courier arrival photos | The first place to look when complaints mention lids or breakage |
| Label proof and sign-off | Final label, warnings, net quantity; date and approver | What you actually sold, and who decided |
Add the MSDS and IFRA documentation for your wax and fragrance oil to the same file; CSI provides these on request on WhatsApp. They are not jar documents, but a buyer or a marketplace that asks for one usually asks for the others.
Warnings and labels before the first sale
The last test is the one the customer reads. Your programme earns you the right to sell the candle; your label tells the customer how to burn it. Common candle-safety warnings, in plain words, are:
Common candle-safety warnings · adapt the wording to your product
Never leave a burning candle unattended; burn within sight. Keep away from children, pets, curtains and anything that can catch fire. Burn on a stable, heat-resistant surface, away from draughts and fans. Trim the wick before each use (CSI's wick trimmer page suggests 1/4 inch). Do not burn for more than about four hours at a time. Stop burning when about 1 cm of wax remains. The glass gets hot: do not touch or move the candle while it is lit or while the wax is liquid. Do not put the lid on a lit candle. Discontinue use if the glass is chipped or cracked.Three rules for the label itself. First, warnings, not promises: never print that the jar or the candle is "safe", "certified" or "tested to" anything you cannot show, because a listing said so. Second, net quantity: India's Legal Metrology (Packaged Commodities) Rules govern net-quantity declarations on pre-packaged goods; check the current requirements for your product and sales channel, and treat this as a pointer, not legal advice. Your weighed fill from test 3 is the number to declare against. Third, fit: a warning sticker that peels off a warm jar has not done its job, which is why the programme labels the burn-down candles.
The Candle Care Stickers Roll is titled a "Candle Safety Sticker Roll", but its page does not show the printed wording; ask us for it and compare it with the list above before relying on it alone.
What the programme costs
Worked example for a new Clear 150 g jar, ten 150 g candles at 8% (12 g of oil and 138 g of wax each), CSI 464, Jasmine Fragrance Oil standing in for your oil (its page states "Recommended load up to 10% soy"), and C2 standing in for your approved wick. CSI live pricing, 26 September 2026.

Everything the programme buys, and what it works out to per candle sold
| Item | For | Cost |
|---|---|---|
| Clear Glass Jar with Golden Lid (150 gram), pack of 20 | Inspection, measurement, lid fit, 10 pours, replacements | ₹1,888.00 |
| Luxury Soy Wax CSI 464, 1 kg + 500 g | 10 candles × 138 g = 1,380 g | ₹767.40 |
| Jasmine Fragrance Oil, 100 g + 50 g | 10 candles × 12 g = 120 g | ₹660.00 |
| Eco Candle Wicks Thick (C2), 20 | 10 candles plus spares | ₹188.80 |
| Pen Thermometer | Every logged pour | ₹354.00 |
| Candle Making Weighing Scale | Water-fills, fills, net quantity, stop line | ₹354.00 |
| Candle Care Stickers Roll, 500 (1 inch) | Warnings on the programme and launch candles | ₹413.00 |
| Programme total | With tools | ₹4,625.20 |
| Programme total | If you already own a checked thermometer and a 1 g scale | ₹3,917.20 |
| Spread over the first 100 candles | Per candle | ₹46.25 |
| Spread over the first 300 candles | Per candle | ₹15.42 |
For scale: the materials for 100 production candles in the same jar come to about ₹22,094.00 (₹220.94 each, at the 10 kg wax and 1 kg oil prices), so the full programme with tools is about 21% of your first hundred candles' materials, and much of it (tools, stickers, spare jars) carries straight into production. Boxes and air-column wrap for the transit test are optional extras here (₹2,236.00 for 50 boxes and a roll) because you will need them at launch anyway. All figures exclude labour, freight and GST.
Argued against our own interest: the cheapest programme is the one that uses what you already own. Don't buy our thermometer or scale if yours pass the checks; don't buy 20 jars if you are only ever going to make 30 candles in that jar (a pack of 10 and no reserves is a smaller, riskier programme, and at least it is one); and don't order production jars until the file is signed.
Diwali is 8 November 2026, 43 days after 26 September 2026. The worked plan finishes sign-off around 24 October with production after that, provided jars arrive in the first days and nothing fails. If a burn-down fails, do not shorten the retest to hit Diwali: launch the new jar for Christmas (25 December 2026) and sell Diwali in a container you have already approved. Ask for a Diwali quote from the same batch you tested, with GST invoice and a dispatch date.

When to run it again
Approval belongs to a combination, not to a jar. Write these triggers on the sign-off page, and rerun the relevant tests when one happens:
New supplier or a jar that "looks the same": the whole programme; near-identical jars differ in inside diameter, base thickness and glass (switching jar suppliers). New batch from the same supplier: inspection and measurement on every batch; a pour-and-cool log on the first production run; burn-downs if the measurements have moved (batch-to-batch variation). New wick, wax, fragrance oil or load: burn-downs and the final third (what to retest when a formula changes). New finish or colour of the "same" jar: the finish test and burn-downs. New lid or packaging: lid fit and transit. A pattern of complaints or breakage: stop, and diagnose before you sell more (the production-breakage split test).
This programme is for: small brands adding a container to a range they sell, from a first gift line to a few hundred candles a month. It is the minimum, not the maximum: importers and high-volume brands should add batch sampling and supplier documentation (import approval). It does not replace: wick selection, which comes first.
What the programme uses
Ranked by how much of the programme each one carries: the jar under test, the warnings every candle ships with, the two measuring tools, then the wax and wick of your final formula. Prices and stock verified 26 September 2026.

150 g · clear · the worked example in this programme
Clear Glass Jar with Golden Lid (150 gram)
We use it as the worked example because its page gives the programme something to test against: "Safe for hot pour up to 85°C", "150g fill capacity", "outer diameter 7cm", "base diameter approximately 6.5cm" and a golden metal lid. That is the page's wording, not a certificate, and CSI publishes no burn-down or breakage data for it; the programme is what turns wording into your own evidence. Its page text is partly raw data and calls the jar both "curved silhouette" and "straight-sided", so measure. The black, red, pink and orange 150 g versions share the wording and are in stock; amber is out of stock. For a first gift or retail line with a lid.
| Pack | Price | Per jar | What it covers |
|---|---|---|---|
| Pack of 10 | ₹944.00 | ₹94.40 | a reduced programme with no reserves |
| Pack of 20 | ₹1,888.00 | ₹94.40 | the full programme: 20 inspected, 10 poured |

Candle Care Stickers Roll | Candle Safety Sticker Roll 500 & 1000 stickers
The listing title calls it a "Candle Safety Sticker Roll" and offers 1 inch (500) and 1.5 inch (1,000) sizes. The page does not show the wording printed on the stickers, so ask for the wording and dimensions and check it covers the warnings in your programme before you rely on it. For brands that want a ready-made care label beside their own. Limitation: a sticker is not your whole warning; your label, box insert or product page still needs the full list.
| Size | Price | Per sticker | What it covers |
|---|---|---|---|
| Pack of 500 (1 inch) | ₹413.00 | ₹0.83 | 500 candles |

tool · pour inside the lower of two limits
Pen Thermometer For Candle Making
The pour-and-cool test and every production pour depend on it. The page states no range or accuracy, so check it in ice water before the programme and record the check in the container file. In a jar that states 85°C, with CSI 464 (stated 80°C – 90°C), you pour at 80°C to 85°C measured in the pitcher. Argued against our own interest: if you already own a probe thermometer that reads close to 0°C in ice water, use it.

tool · fill weight, net quantity and burn records
Candle Making Weighing Scale
The programme weighs water-fills, test pours, finished candles and remaining wax at the stop line, and your net-quantity label depends on those numbers. The page describes a digital scale in "grams or ounces" with "simple one-button operation" and states no capacity or reading step; check yours reads to at least 1 g, and 0.1 g if you weigh small additive amounts. Argued against our own interest: a kitchen scale with a tare button that reads single grams does the job.

wax · the programme wax
Luxury Soy Wax CSI 464 (Flakes Form) For Container Candles
The page states "Pour Temperature 80°C – 90°C" and "Fragrance Load Up to 10%". The programme uses your final formula, so if CSI 464 is your wax, 1.5 kg covers ten 150 g candles at 8% (1,380 g). Change the wax later and the burn-downs must be repeated. Limitation: flat per gram from 1 kg up, so there is no saving in buying 10 kg before the jar is approved.
| Size | Price | Per gram | What it covers |
|---|---|---|---|
| 500 g | ₹260.00 | ₹0.52 | the top-up to 1.5 kg |
| 1 kg | ₹507.40 | ₹0.51 | 7 of the 10 programme candles |
| 5 kg | ₹2,537.00 | ₹0.51 | 36 production candles |

wick · the approved wick, never a new one
Eco Candle Wicks | Eco Wicks for Candle Making
The programme tests the wick you have already approved for this jar; it is not the place to choose one. If you have not bracketed a wick yet, do that first with C1, C2, Cotton Braided or wooden rungs (see the Candle Wicks collection and the diameter-and-wick hub). Eco C1 is ₹5.90 and C2 ₹9.44 per wick at every pack size. Limitation: two sizes only; neither is a verdict for any jar.
| Pack | Price | Per wick | What it covers |
|---|---|---|---|
| Thin (C1) / 20 Wicks | ₹118.00 | ₹5.90 | the programme, if C1 is your approved wick |
| Thick (C2) / 20 Wicks | ₹188.80 | ₹9.44 | the programme, if C2 is your approved wick |
| Thick (C2) / 100 Wicks | ₹944.00 | ₹9.44 | first production after approval |
20 wicks cover 10 programme candles with spares. Buy 20 C2 — ₹188.80
The CSI principle
A listing is a claim. A signed container file is evidence.
Quote the wording, inspect every jar, respect the lower of the stated limits, burn three to the stop line, grade the finish, post two, label with warnings rather than promises, and write down what would make you test it again.
"Your customer never sees your test log. They see a candle that burned the way your label said it would."

Why trust this guide
CandleMakingSuppliesIndia sells the jars, wax, wicks, tools and stickers named here, and does not sell finished candles. This page tells you that our own "hot-pour up to 85°C" wording is not test data, that we publish no burn-down or breakage data, that our sticker page does not show its printed wording, and that you should not buy our tools if yours pass. A brand that approves containers properly is a brand that is still buying from us next year.
Every price was verified on CSI's live store on 26 September 2026; every pack in a pick table is in stock on that date, and the out-of-stock amber 150 g jar is named as such. Product wording is quoted from the pages; where a page is silent or contradicts itself, we say so.
The eight-test list, the minimum counts, the four-week schedule, the pass lines and the retest triggers are editorial judgement, not an industry or legal standard. Session length and the 1 cm stop line are common practice. For bulk pricing, GST invoicing, and MSDS and IFRA documentation on request, message us on WhatsApp at +91 7397976926.
Frequently asked questions
How do I safety test a candle jar before selling candles?
Quote the listing and get supplier answers in writing, inspect every jar, measure and weigh the fill, run a logged pour-and-cool test inside the stated limits, burn at least three candles to about 1 cm of wax, test any coating, check lids and transit, and label with warnings.
How many burn tests should I do on a new candle jar?
At least three full burn-downs of your final formula and approved wick, to the stop line, with the final third watched, plus three reserves in case one fails for a wick or draught reason. Three is a floor, not a target.
What warnings should be on a candle label in India?
Common warnings: burn within sight, keep away from children, pets and flammables, use a heat-resistant surface away from draughts, trim the wick, limit sessions to about four hours, stop at about 1 cm of wax, and don't move a lit candle. Check current Legal Metrology requirements for net quantity; this is not legal advice.
Can I say my candle jar is heat safe if the supplier says so?
Don't. A supplier's wording is their claim, not your evidence, and it may describe only a pour temperature. Quote it in your records, run your own tests, and put warnings on your label rather than a "safe" or "certified" claim.
How much does it cost to test a new candle container?
In our worked example with 20 Clear 150 g jars, CSI 464, fragrance oil, wicks, a thermometer, a scale and safety stickers: ₹4,625.20, or ₹3,917.20 if you own the tools. Spread over the first 100 candles, about ₹46.25 each.
Do I need to retest if I change my candle jar supplier?
Yes, the whole programme. Near-identical jars can differ in inside diameter, base thickness and glass. A new batch from the same supplier needs inspection and measurement; a new wick, wax, oil or load needs new burn-downs.
Your next container, approved
Eight tests, ten poured candles, one signed file: ₹4,625.20.
Twenty Clear 150 g jars, 1.5 kg of CSI 464, 150 g of oil, 20 wicks, a thermometer, a scale and a roll of care stickers. Four weeks from now you will have three burn-downs, a pour-and-cool log, two couriered candles and a label you can stand behind.

About this guide: the capstone of CSI's glass-safety cluster: the minimum eight tests a small brand should complete before selling a new container (paper check, inspection, measurement, pour-and-cool, three burn-downs, finish, lid and transit, labels), the container file, label warnings, a costed worked programme, a 43-day schedule to Diwali, and retest triggers.Customer reviews: The six reviews at the top of this page are genuine, published Judge.me reviews left by CSI customers on the product pages named on each card — Black Glass Jar with Black Lid (150 gram) (Deliveries Starting 5th Dec), Clear Glass Jar with Golden Lid (150 gram), Eco Candle Wicks, Eco Soy CSI 400, Lavender Fragrance Oil, White Matte Glass Jar.

Non-price figures: "Safe for hot pour up to 85°C", CSI 464's 80°C – 90°C and the wick trimmer page's 1/4 inch are page wording. Load is a percentage of total candle weight (150 g at 8% = 12 g oil + 138 g wax). Session length, the 1 cm stop line and the listed warnings are common practice; the test list, counts, schedule and cure length drawn in the diagram are editorial judgement. Legal Metrology is mentioned as a pointer, not legal advice. Dates are calendar facts; the schedule is a worked plan, not a delivery promise. Costs exclude labour, freight and GST.
