Not who to buy from — sibling guides cover that. This one is about the glass itself: how a burning candle loads it, why a jar that is perfectly sound for storage can crack with a wick in it, and what you must test before you build a range around a vessel.

Quick answers — read this first
What actually breaks a candle jar? Not heat — a temperature difference across the glass. The inside face gets hot and tries to expand, the outside face stays cool and refuses, and the outer surface is pulled into tension. Glass is strong in compression and weak in tension, so the crack starts at the coolest, most flawed outside surface and runs.

Why does the base fail more than the wall? Because the base is usually the thickest part of the jar, and thickness makes the temperature difference across the glass larger, not smaller. It is also where the flame ends up, and where the wax that was absorbing the heat has gone.

Can I use any pretty glass jar? Only after you have burned one to the bottom three times. A jar that is sound for storing pickle has never been asked to take four hours of one-sided heat, forty times over.

Which CSI glass takes heat best? Borosilicate, at ₹200.00 for the 600 g jar — borosilicate expands far less for the same temperature rise, so the same heat generates much less stress.
The short answer
Judge glass on four properties, in this order: whether it is annealed and sold for candles, base thickness, wall thickness, and internal diameter. Colour and finish are the last decision, not the first.
Burn-test every new vessel to the bottom before you sell in it. Three jars, three full burn-downs past the 10 mm line, on a test unit you are willing to destroy. Photographing a filled jar proves nothing about how it behaves in hour thirty-eight.
Print the safe-use rules on the candle. Stop at 10 mm, burn no longer than four hours, never relight a hot jar, trim the wick to 5 mm, keep it centred. Candle Care Stickers are ₹413.00 per 500 at 1 inch, or ₹699.00 per 1000 at 1.5 inch.

Where the heat goes, and where the glass gives way 10 mm 1 — Full jar: the wax mass soaks up the heat and spreads it 2 — Wall: hot inner face expands, cool outer face resists = tension outside 3 — 10 mm stop line: below this the wax heat-sink is gone 4 — Danger zone: thickest glass, flame closest, nothing left to absorb it Cross-section · flame descends toward the base as wax is consumed
The failure is almost never at the moment of lighting. It is at the end of the burn, at the base, where the glass is thickest, the flame is nearest and the wax that was absorbing the heat has been consumed. That is the whole argument for the 10 mm stop line and for burning a test jar all the way down before you ever sell in that vessel.

Straight answer
What makes a glass jar suitable for a candle, and how do you buy it in India?
A candle jar has to survive sustained, one-sided, repeated heating — three to four hours at a time, forty or more times, with the heat source moving steadily closer to the base. Glass fails under that when one part of it is hot and an adjacent part is cool, because the hot part expands against the cool part and puts the cool outer surface into tension, which is the one load glass is bad at. Three things decide the outcome: how evenly thick the glass is, how well it was annealed after forming, and how much wax is left to absorb heat at the moment you are testing. That last one is why the end of the burn is the dangerous part, and why the only meaningful test is to burn a jar to the bottom, three times, before you sell a single candle in it. Buy from the Containers For Candle Making collection — 80 products — and ask for fill capacity, internal diameter and wall thickness before you commit a range to a vessel. Then size the wick to that diameter using the wick-by-diameter guide, and print the stop-at-10 mm rule on a care sticker.
One line: glass breaks on temperature difference, not temperature — so buy for even walls, a sane base and a known diameter, then burn one to the bottom before you trust it.
The rules that follow from the glass belong on the product, not in a caption nobody reads. Candle Care Stickers Roll: ₹413.00 for 500 at 1 inch (₹0.83 each), or ₹699.00 for 1000 at 1.5 inch (₹0.70 each). That is under a rupee to put "stop at 10 mm, never relight hot glass" in the customer's hand.

Glass and heat: what is actually happening in that jar

Glass does not break because it got hot. It breaks because one part of it got hot while the part next to it did not.

Start with the load case. A candle is not a brief heat event: it is three to four hours of continuous, one-sided heating, repeated thirty to fifty times, with the heat source descending through the vessel as the fuel is consumed — and the thing absorbing most of that heat gets smaller every hour. A jam jar is filled hot once and then sits cold for a year. Nothing else a jar does looks like a candle.

Now the material. Glass expands when heated, and the property that matters is the coefficient of thermal expansion — how much a given length grows per degree. Ordinary soda-lime container glass, which is what nearly every candle jar in India is made from, has a relatively high one; borosilicate has a much lower one.

The mechanism, in order. The flame heats the wax and the inner face of the glass. Glass is a poor conductor of heat — that is why a glass mug keeps tea warm — so heat does not cross the wall quickly. A gradient develops through the thickness: the inner face hot, the outer face cooler because it is losing heat to the room. The hot inner face tries to expand and the cooler outer face restrains it, so the inner face ends up in compression and the outer face in tension.

This is the fact to carry away. Glass is enormously strong in compression and weak in tension. Every candle-jar failure you have seen is a tensile failure on the cooler surface, usually the outside, and it starts at a flaw — a transit scratch, a chipped base rim, a mould seam, a microscopic defect from forming. The flaw concentrates stress at its tip, the crack initiates there, and once it starts it runs faster than you can react.

Which leads to the counter-intuitive part, and the one that costs Indian makers most. Thicker glass is not safer glass. Thickness is the distance over which the gradient develops: make the wall thicker and, for the same heat going in, the inner face runs hotter relative to the outer face, so the temperature difference is bigger and the tensile stress is bigger. Heavy glass also stores more heat between burns. Thin, even glass sheds heat quickly and runs closer to one uniform temperature, which is the safe condition.

So the word to insist on with a supplier is even, not thick. A jar with a 3 mm wall on one side and 6 mm on the other — an ordinary outcome of cheap mould work — has a built-in temperature difference the moment you light it. Run a finger round the inside and you can often feel the wall change. That five-second check catches more bad vessels than any specification sheet.

The CSI principle
Heat does not break glass. Differences in heat break glass.
Even walls, a centred wick, no draught across one face, no cold surface under a hot jar, and a wax level that never drops so low that nothing is left to absorb the flame. Each is the same instruction, stated about a different part of the system.

Annealing: the property you are buying and cannot see

A jar is formed soft and hot. Cool it quickly and the outside sets while the inside is still contracting, freezing permanent internal stress into the finished jar. Annealing is the controlled slow cool through the band where glass can still relieve stress, gentle enough that those stresses relax out before the glass rigidifies. A properly annealed jar starts at near-zero residual stress, so its full strength is available to resist what your candle adds. A poorly annealed one has already spent part of its strength holding itself together, and goes over the limit sooner — sometimes only on the fortieth burn, which is the worst case commercially, because by then the candle is in a customer's home.

You cannot inspect for annealing
Residual stress is invisible without polarised light, and no maker is setting up a polariscope. That is exactly why the burn test below is not optional: annealing quality is inferred from behaviour, not from looking. It is also why reordering the same vessel from the same supplier beats saving a few rupees on an unknown one — consistency of process is what you are paying for.

Why borosilicate sits in its own category

Thermal stress scales with the coefficient of expansion. Borosilicate's is a fraction of soda-lime's, so the same temperature difference across the wall generates proportionally less stress. It is not stronger glass in the ordinary sense — it is glass that cares much less about temperature differences. On the CSI range that position is held by the Borosilicate Glass Jar 600 g with Golden Lid at ₹200.00. Two caveats: tolerance is not permission to abuse the candle, because a wick licking the wall still overheats one spot and the 10 mm rule still applies; and at 600 g this is a large, long-burning candle, not a drop-in replacement for a 150 g gift jar.

Why a jar that is fine for storage cracks with a candle in it

This failure catches new brands late, usually after the first hundred units have shipped. A maker finds a beautiful vessel — a pickle jar from a wholesale market, a decorative piece from a homeware supplier. Thick, heavy, clearly good glass. They fill it, photograph it, burn it for an hour, and put it on sale. Six weeks later a customer sends a photograph of a jar split around the base.

Nothing was wrong with the glass. It was designed, formed and annealed for a different load case: internal pressure, the vacuum of a cap, one brief near-uniform hot-fill cycle, and being knocked about in crates — not forty sessions of localised heating from a flame inside it. "Food-safe" describes what will not leach into your pickle. It says nothing about how the jar behaves with a wick in it.

The three ways it typically goes wrong. One: the base is a thick moulded slab with a punt or seam, so it develops the largest gradient in the jar exactly where the flame ends up. Two: wall thickness is uneven because the mould was cut for volume and cost, so the two sides can never reach the same temperature. Three: the glass was annealed to a schedule adequate for packaging, which is a lower bar than a vessel thermally cycled dozens of times. Any one of the three survives photograph day and fails in week six.

CSI sells a container worth naming here precisely because it sits on that line. The 200 ml Salsa Glass Jar with 63 mm lug cap is food-packaging glass in origin — the lug cap is the giveaway. It is widely and successfully used for candles and at ₹29.50 each in 50s and 100s the economics are the best in our range. It is also exactly the sort of vessel this section warns you about, which is why we would rather you burn-tested it than discovered the point yourself. Buy five at ₹200.60, destroy three, then decide.

The burn test, in full

Three jars, three wicks and about a day and a half of unattended time per vessel. Run it for every new container, and re-run it whenever you change wick size, wax or fragrance load, because all three change how much heat reaches the glass.

1
Pour three identical jars to your real production recipeSame wax, load, wick, fill height and cure. A test using a different recipe from your production line has tested nothing — if you pour at 10% with CSI 464, test at 10% with CSI 464. Three jars, because glass varies within a pack.
2
Burn in four-hour sessions, on a trivetNo cloth, no wooden board, no marble slab pulling heat out of one side of the base. Keep the jars out of any draught — a fan across one face creates exactly the one-sided cooling that puts the opposite face into tension. Cool completely to room temperature between sessions.
3
Touch the outside wall at the end of every sessionYou are not looking for a number, you are looking for a reject. If you cannot rest a hand on the wall at the level of the melt pool for a couple of seconds, that jar-and-wick combination runs too hot — and the first answer is a smaller wick, not a different jar.
4
Burn all the way to the bottom — past 10 mm, deliberatelyEveryone skips this, and it is the only step that tests the thing that actually fails. On a test jar, and only a test jar, keep going until the wick drowns or dies. You are watching what the vessel does when the wax heat-sink is gone and the flame sits a few millimetres above the base. If it cracks, it cracks here — better in your workshop than on a customer's shelf.
5
Inspect cold, and keep the evidenceCheck the base rim and lower wall in strong light for hairline crazing — a fine network of surface cracks that has not yet run. Crazing is a pass-with-warning, not a pass. Photograph each jar, note vessel, wick, wax and pack batch, and file it: when you reorder from a different production run you have a baseline to test against.
Reject the combination, not the jar
A cracked test jar usually means too much wick for that vessel, not bad glass. Step down one size and test again before writing off a container you like — Eco Candle Wicks ship in Thin (C1) at ₹59.00 for 10 and Thick (C2) at ₹188.80 for 20, so testing both costs less than the jars do. Only when the smallest wick that still opens a full pool is also the one that cracks the glass do you have a glass problem.
A photograph proves the jar looked right on day one. Only a burn-down proves it is still a jar on day forty.

The safe-use rules the glass dictates

Every rule below follows directly from the mechanism above. None is decorative safety language — each stops a specific temperature difference forming in a specific place. Which is the argument for printing them: a customer who understands why follows the rule, and one who follows the rule does not send you a photograph of a broken jar.

Care card copy · and the physical reason behind each line
Five rules, each traceable to the glass
Rule Why the glass needs it
Stop burning when about 10 mm of wax remains The remaining wax is the heat sink. Below roughly 10 mm there is not enough left to absorb what the flame puts into the thickest, most stressed part of the jar
Burn no longer than four hours at a time Heat accumulates faster than the outer surface can shed it to the room, so the gradient across the wall keeps widening
Never relight a hot jar — let it cool fully Relighting stacks a second cycle on glass that has not returned to a uniform temperature, so the burn starts with stress already in the wall
Trim the wick to 5 mm before every light An untrimmed wick gives a tall, sooting flame that puts more heat into the vessel and wanders off the centre line
Keep the wick centred; never let the flame touch the wall A flame licking one side makes a hot spot next to relatively cool glass — the sharpest temperature difference you can create in a jar

Add two more if you have room: never move a lit or hot jar, and never set a hot jar on cold stone, marble or metal — that pulls heat out of the base in seconds, thermal shock from the opposite direction to the one everybody worries about. Both are common household habits and both break jars.

Print it, do not caption it. Candle Care Stickers Roll — ₹413.00 for 500 at 1 inch (₹0.83 each) or ₹699.00 for 1000 at 1.5 inch (₹0.70 each), CSI live pricing, September 2026. The 1.5 inch takes the full rule set legibly; the 1 inch suits votives.

Internal diameter drives the wick

One paragraph, because this belongs to the wick guide. The only jar dimension that sets wick size is the internal diameter at the level the wax sits — not fill weight, not the outside measurement, not the family. The wick must open a melt pool that reaches the wall in two to three hours and no faster: too small and you tunnel, too large and you overheat the glass, which loops straight back to the failure mechanism at the top of this page. Measure across the wax line in millimetres, write it on your record sheet, and choose from there. Eco Candle Wicks ship in Thin (C1) from ₹59.00 for 10 and Thick (C2) from ₹188.80 for 20 so you can bracket a diameter cheaply, and the whole method is set out in the complete wick guide by diameter.

What to ask a glass supplier before you commit

Sibling guides cover supplier choice in general — sourcing for a business, consolidating onto one supplier and wholesale across India. These seven are specific to glass. Send them as a list — a supplier who answers all seven quickly knows what they are selling.

The glass buyer's seven questions
Ask before the first order, not after the third
Ask Why it decides something
Fill capacity in grams of wax Millilitres of water is not grams of wax, and usable fill sits below the rim. Your costing runs off this number — get it in grams
Internal diameter in millimetres The only dimension that sets the wick. Without it you are guessing, and a guessed wick is the most common cause of a cracked jar
Wall thickness, and base thickness separately Different numbers, and the base is the one that fails. What you want to hear is that the wall is even, not that it is thick
Is it intended for candles, or is it repurposed food glass? Either answer is useful. Repurposed glass is not disqualified — it just moves the burn test from advisable to mandatory
Pack size and minimum order Decides whether you can trial a colour at all. A family sold only in 20s is a different commitment from one sold in 5s
Breakage policy in transit Glass moving through a parcel network breaks sometimes. What matters is whether that is your loss or theirs, agreed before it happens rather than argued after
Restockability — will this exact jar exist in six months? The one nobody asks. A jar built into your photography, packaging dimensions and wick testing is expensive to replace. Ask whether it is a repeat line or a one-off import

The last is the expensive one. When a vessel changes, everything attached to it changes: the wick you validated, the carton that fitted it, the label die-cut to its curve, your photography, and the burn-test record that justified all of it. Treat a container choice as a two-year commitment. If the answer is vague, buy two years of stock now or design with a vessel that is clearly a repeat line.

Ask for the numbers you are not given
Published listings rarely carry internal diameter or wall thickness, and that is as true of ours as anyone's. Message +91 7397976926 with the product name before you buy a hundred — it costs us a minute and saves you a season. GST invoicing and documentation run on the same channel; see how CSI handles online ordering.

Where our glass range is thin — check before you design around it

This is the section a supplier is not supposed to write, and the one most likely to save you money. A glass range is only as good as the parts of it in stock when you need them, and on the 10 September 2026 pull the CSI container range has real, specific gaps. Confirm stock before you build a collection, not after.

Borosilicate is effectively one SKU. Having spent several hundred words on why borosilicate is the material answer to thermal stress, the honest position is this: of three borosilicate listings, only the 600 g jar at ₹200.00 is in stock. The 300 g at ₹120.00 and the 250 g pack of 5 at ₹375.00 are both out. If your plan was a borosilicate range across three sizes, you do not have a range — you have one large jar. Ask about restock dates before you commit artwork.
The entire bamboo-lid category is out of stock. Glass Jar With Bamboo Lid at ₹153.40, Amber Glass Jar with Bamboo Lid at ₹171.10, the White Iridescent Jar with Bamboo Lid 300 g at ₹150.00 and the Amber Glass Jar 250 ml at ₹110.00 are all unavailable on this pull. Bamboo-lid jars are one of the most requested looks in the Indian market — if that is your aesthetic, this is not currently the place to source it, and you should plan around that rather than wait.
Coloured votives and coloured frosted finishes have holes in them. In the votive family, purple matte, brown matte and pink matte are out; among the Colorful Votive Glass Jars, amber, red and orange are out and clear is available only as a single unit. In the ₹70.80 family, frosted brown and orange frosted are out and pink matte is available only in the pack of ten. The Colorful Candle Containers in pink, purple, yellow and green are all four out. A range built on a colour already unavailable in September is a range you will be reworking in October.

A structural point against ourselves, too: the most useful specifications on this page — internal diameter, wall thickness, base thickness, annealing schedule — are not published on our listings, and not on most Indian suppliers' listings either. That is a weakness of the market, not a feature. The workaround is to ask, which is why the WhatsApp number appears twice here — but a workaround is not a spec sheet and we will not pretend otherwise.

And most simply: if the vessel you want is not here, buy it where it is. A brand held together by a jar it cannot reorder is worse off than one buying glass from a second supplier while buying wax, wicks and fragrance here. Consolidation is a real efficiency — the case is in the one-supplier guide — but it is an efficiency, not a principle, and glass is where it is most often worth breaking.

Why trust this guide

CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. On a page about glass, the commercially convenient version would recommend the heaviest, most expensive jar in the catalogue, because heavy glass reads as premium and costs more. We have argued the opposite — that even walls beat thick walls, that a ₹31.86 votive is a better burn-test vehicle than a ₹354.00 dome-lid jar, and that two of our three borosilicate listings are out of stock. A maker whose jars crack does not reorder.

The physics on this page — thermal expansion, the compression-versus-tension behaviour of glass, the role of wall thickness in setting the temperature gradient, and the function of annealing — is standard glass-material behaviour and applies to any supplier's jars, not just ours. We have deliberately not published test results, temperature thresholds or breakage rates, because we have not run a controlled programme that would justify quoting numbers. What we have given you instead is a protocol you can run yourself in a day and a half, which is worth more than a figure you would have to take on trust.

Every price is taken from live CSI stock on 10 September 2026 and links to the product page, where current pricing and availability always take precedence. Stock changes fast in the run-up to Diwali on 8 November 2026.

Frequently asked questions

Why did my candle jar crack at the end of the burn and not at the start?
Because the end of the burn is the hardest moment for the glass. Three things happen at once: the flame is at its closest to the base, the base is usually the thickest part of the jar and therefore develops the largest temperature difference across it, and the remaining wax — which had been absorbing and spreading the heat — has been consumed. The glass is taking more heat, in a smaller area, with nothing left to buffer it. That is the whole reason for the 10 mm stop line, and the reason a test jar must be burned past it deliberately so that you find out in your workshop rather than in a customer's home.
Can I use ordinary food or pickle jars for candles?
Sometimes, but never without testing. Food-packaging glass is designed and annealed for internal pressure, a cap seal and one brief near-uniform hot-fill cycle — not for forty sessions of localised heating from a flame inside it. "Food-safe" describes what will not leach into the contents; it says nothing about thermal cycling. The 200 ml salsa jar with a 63 mm lug cap at ₹29.50 each in 50s is exactly this kind of glass and is widely used for candles successfully — buy the pack of five at ₹200.60, destroy three of them in a burn test, and then decide.
Is thicker glass safer for candles?
No — and this is the most expensive misconception in container buying. Glass is a poor heat conductor, so thickness is the distance over which a temperature gradient builds up. A thicker wall means the inner face runs hotter relative to the cooler outer face, which means a larger temperature difference and more tensile stress on the outside surface, which is where cracks start. Thick glass also stores more heat between burns. What you want is glass that is even in thickness and properly annealed, not glass that is heavy.
Which CSI glass jar handles heat best?
The Borosilicate Glass Jar 600 g with Golden Lid at ₹200.00. Borosilicate has a much lower coefficient of thermal expansion than ordinary soda-lime container glass, so the same temperature difference across the wall produces far less stress. Two caveats: it is a large 600 g fill, so it is not a substitute for a 150 g gift jar, and the 300 g and the 250 g pack of five are both out of stock on the September 2026 pull — check before you plan a borosilicate range.
How many jars should I burn-test, and for how long?
Three jars per vessel-and-wick combination, burned all the way to the bottom. Use four-hour sessions with a full cool-down between them, on a trivet or tile, away from draughts, poured to your real production recipe. Three rather than one, because glass varies within a pack. Re-run the test whenever you change the wick size, the wax or the fragrance load, because all three change how much heat reaches the glass. Budget roughly a day and a half of unattended time — on a ₹70.80 jar that is about ₹212 of glass to validate a whole product line.
What is the cheapest glass candle container at CSI?
The Mini Glass Jars at ₹21.24 each in packs of 100 (₹2,124.00), in black or golden. For a small jar with a lid, the Clear Glass Votive 70 g is ₹31.86 each at ₹159.30 for five or ₹318.60 for ten. Cheapest is not automatically wrong — a small jar means a small wick, less heat and a shorter burn — but it is still a jar you must burn to the bottom before you sell in it.

Material claims: The thermal-stress description here — expansion on heating, the compression and tension distribution across a heated wall, the effect of wall thickness on the temperature gradient, the purpose of annealing, and borosilicate's lower coefficient of thermal expansion relative to soda-lime glass — is standard glass-material behaviour. No CSI test results, temperature thresholds, breakage rates or certifications are claimed on this page, and none should be inferred. Diwali 2026 falls on 8 November. Prices and availability change — the linked product pages are always authoritative.
