My New Soy Wax Batch Feels Softer than the Previous One and My Candles Burn Differently — How Do I Verify Whether the Wax Itself Changed?
शेयर करना
How do I verify it? Pour unscented twins: two candles from the old bag and two from the new, same jar, same wick, same pour temperature, same shelf. Log how fast each sets, the surface at 24 hours, the texture on day 2 and day 7, melt and set readings on one thermometer, and one four-hour burn each.
What decides it? If old and new twins match on the same day, the wax is not your change, and the room or the season probably is. If the new twins differ in both duplicates, on set, texture, readings or pool, the lot behaves differently in your system: tell us with the lot numbers and re-check your wick.
What does it cost? ₹910.80 of materials in the worked example (four twins plus a melt check, 600 g and 200 g of wax), excluding labour, freight, packaging and GST; new cash of at most ₹413.00 if you own no thermometer or spare wicks.

"Softer" is a reading, not a verdict
Container soy and coconut-soy waxes are soft by design compared with pillar waxes, and how soft they feel depends heavily on temperature: the same wax commonly feels firmer on a cool morning and softer on a warm afternoon (a tendency, not a figure). So in our judgement the most common reason a "new bag feels softer" is that it is being handled at a different time of year from the old one. Late September sits at the end of the southwest monsoon, which runs roughly June to September; a bag opened in cooler months and one opened now are not being felt under the same conditions.
Form matters too. Flakes, chunks, a set candle and a spoonful of scraped wax all feel different, and fragrance oil commonly softens the feel of a finished candle compared with plain wax. If last month you pressed a finished, scented candle and this month you are pressing flakes, the comparison says nothing about the lot.
Storage is the other half. CSI 468's page says "Store in a cool, dry environment. Keep sealed when not in use." A bag left open near a window, on a warm floor or in a hot storeroom has had a different life from one kept sealed and cool, whatever lot it came from. Note where each bag has lived before you compare them.
What else makes a candle soft or burn differently
The table ranks the causes behind "the new batch feels softer and burns differently", most common first. The ranking is editorial judgement; CSI publishes no failure statistics. The unscented twins exist to separate the last row from the first four.
| # | What you notice | Likely cause | Rules it in | Rules it out |
|---|---|---|---|---|
| 1 | Softer now; you're comparing with how the old bag felt weeks ago | Season and room temperature | Same-day check: no difference | Same-day check: new bag clearly softer |
| 2 | Finished candles softer; a new oil order or higher load went in | Oil or load, not wax | Unscented twins match | Unscented twins differ |
| 3 | New bag stored open or somewhere warm | Storage history | Only the badly stored bag differs; a sealed part of it doesn't | Both stored alike and both differ |
| 4 | Rough or pitted tops, slower set, more wet spots | Pour temperature or cooling (process) | Pour and room temperatures differ on the batch sheet | Twins poured together still differ |
| 5 | New lot differs in the unscented twins, both duplicates | The wax lot, in your system | Twins differ on set, texture, readings or pool | Twins match |
Rows 1, 2 and 4 belong to other posts once you've ruled them in: a new oil order goes through the new-order gate, a season-driven change to the winter-summer comparison, and rough tops to the pour-temperature bracket. If both your wax and your wicks changed at once and the candle now tunnels, the swap-back 2×2 crosses the two lots in one pour. This page keeps to one question: did the wax change?
The unscented twin pour
You need 400 g from each bag: 300 g for two twins and 100 g for the melt-and-set readings. If the old bag is empty, see the fallback at the end of this section. Everything except the lot is held the same: jars from one delivery, wicks from one pack, one pot per lot of the same kind, one thermometer, one pour temperature, one shelf.
| Item | Basis | Used | Value |
|---|---|---|---|
| CSI 468, lots O and N | 10 kg at ₹6,370.00 (₹0.64/g) | 600 g for twins (300 g each) | ₹382.20 |
| Clear Glass Jar with Golden Lid (150 gram) | Pack of 10 at ₹944.00 | 4 jars | ₹377.60 |
| Eco Candle Wicks Thin (C1) | Pack of 10 at ₹59.00 | 4 wicks | ₹23.60 |
| Four twins | 4 candles | ₹783.40 (₹195.85 each) | |
| Melt-and-set check | 10 kg price | 200 g (100 g each) | ₹127.40 |
| Whole check | from stock you hold | ₹910.80 |
Material value, excluding labour, freight, packaging and GST. The new cash is nothing if you own a thermometer and spare wicks, and at most ₹413.00 for a Pen Thermometer and ten C1 wicks if you own neither.
Melt and set readings against the page figures
The diagram at the top shows where CSI 468's page figures sit: "Melting Point 50°C – 53°C" and "Pour Temperature 58°C – 60°C". For reference it also shows CSI 464's stated pour of 80°C–90°C and the 150 g jar's "Safe for hot pour up to 85°C". A home thermometer in a small pot is not a laboratory melting-point test, and CSI does not state the method behind its page figures, so do not treat a reading of 49°C or 54°C as proof that a lot is "out". What you can compare fairly is the old lot against the new one, read the same way on the same instrument.
The method
Check the thermometer in crushed ice and water first and note any offset. Put 100 g of each lot in identical small heatproof containers standing in the same warm-water bath. Clear point: as the bath warms, stir each gently and note the temperature at which the last visible solid disappears. First skin: lift both out onto the same surface, and note the temperature at which a skin first forms across the top. Repeat the whole cycle once. You now have four numbers per lot.
If the old and new lots' readings overlap across the two repeats, the melt gives no sign of a change, whatever your thumb said. If the new lot reads consistently lower or higher than the old in both repeats, and by more than the spread between your own repeats, the lot behaves differently in your hands; write the figures down with both order numbers. How big a gap matters depends on your thermometer and your candle, so we give no threshold; the twin burn below decides whether it matters.
The twin burn and the verdict
At the age you normally test (many makers burn-test soy at day 7 as common practice), burn O1 and N1 for four hours, spaced apart, out of draughts, within sight. Unscented candles can share a session because you are reading wax, not scent. Log pool diameter at one, two and three hours, whether the pool reached the jar edge (commonly cited rules of thumb expect about 3–4 hours, or roughly an hour per 2.5 cm of width, about 2.8 hours for the 7 cm jar), pool depth at the end with a skewer (about 0.5–1 cm is a common target), flame height against a card marked in centimetres, and any soot. Repeat with O2 and N2.
| What you see | What it points to | Next step | Purchase |
|---|---|---|---|
| Same-day feel, set, surface, readings and burn all match | The wax is not what changed | Season, oil, load or process: back to the hub's suspect order | Nothing |
| N softer on the same day; set, readings and burn match | A handling difference that doesn't reach the burn | Carry on; note it on the batch sheet; tell us with lot numbers | Nothing |
| N sets slower, surface rougher; burn matches | Appearance only, or cooling sensitivity | Slow the cooling; see 3271 and 3272 | Nothing |
| N's pool wider or deeper, or flame taller, in both twins | The lot burns hotter in your jar | Re-check the wick one step down (from C1, the thinner Eco wick, that means another wick type) against your current wick, full jar; tell us with lot numbers and logs | Possibly one pack of the smaller wick |
| N's pool smaller or slower in both twins | The lot burns cooler in your jar | Re-check one step up, full jar; if both lots and wicks changed, the 2×2 | Possibly one pack of the larger wick |
| Twins disagree with each other | Noise: wick position, draught, jar | Repeat the odd pair; check wick centring | Nothing |
A lot that differs in your twins behaves differently in your system; that is not the same as a lot that is out of specification, and CSI publishes no lot data to compare against. Send us the logs, photos and both order numbers and we will look at them with you. Any wick change that follows must pass the full jar, down to about 1 cm of wax left, before it goes into production; glass heat is never judged by touching the jar.
What not to buy for a softer bag
If the twins match, the answer to a softer feel in summer is usually storage and handling: keep bags sealed and cool as the page says, let finished candles set fully before packing, and pack in the coolest part of the day. None of that costs anything.
The kit for a wax-lot check
Four items: the worked example's wax, the thermometer that makes every reading comparable, and the wick and jar held constant. Chosen on page statements, price per unit and stock on 26 September 2026; CSI has no measured burn data, so nothing is ranked on performance.

CandleMakingSuppliesIndia sells the wax, thermometer, wicks, jars and additives named here, and does not sell finished candles. This page still tells you that a new bag cannot testify about an old one, that our hardening additives are the wrong first answer, and that any working probe thermometer does this job.
Every price and per-gram figure was verified on CSI's live store on 26 September 2026; every size in the pick tables is in stock on that date, and the tables are built to flag any that is not. Temperatures, loads and storage wording are quoted from the product pages; where a page is silent in the text we captured, we say so. CSI publishes no lot or batch data, composition or reformulation notices, and nothing here implies that a CSI batch changed.
