Multi-batch production · consistency
Customers never see your batches. They see a row of candles on a table and notice the one that's paler, weaker or lower in the jar. Consistency across batches doesn't come from skill on the day. It comes from a recipe written in grams, a scale, and a sheet that is filled in every time.
8.16%
what an 8% batch actually becomes if the wax is under-weighed by just 200 g in a 10 kg melt — why every batch is weighed, not estimated · arithmetic on the batch recipe
Quick answers — read this first
How do I keep fragrance strength the same across batches? Write one per-batch recipe by weight (here 9,200 g wax + 800 g oil for 50 × 200 g candles at 8%), weigh both on a scale every time, add the oil at the same temperature and stir for the same time, and cure every batch for the same period. Under-weigh the wax by 200 g and the batch becomes 8.16%.

How do I keep candle colour identical in every batch? Use the same dye from the same order, dose it by weight per kilo of wax at the rate you settled on in testing (dye doses aren't published — follow the product page), and compare each batch with a reference chip poured from the approved batch. A colour master made once for the whole order helps.

How do I keep fill weights consistent? Set a target and a tolerance before you start, for example 200 g ± 2 g (working assumption). Tare every jar, weigh-check a sample from each batch, and record the average. A batch outside the tolerance is investigated before it is packed.

What goes on a batch sheet? Batch number and date; wax bag and oil bottle numbers; weighed wax, oil and dye; temperatures at oil addition and pour; stir time; room temperature; number poured; fill checks; rejects; and who poured. See the template.
The short answer
Recipe: Per batch of 50 × 200 g at 8%: 9,200 g Luxury Soy Wax Chunks + 800 g Vanilla Bean + dye at your tested rate per kg of wax. Weigh, never estimate.
Sensitivity: Wax +200 g → 7.84% · wax −200 g → 8.16% · oil +50 g → 8.46% · oil −50 g → 7.54%.
Controls: Colour reference chip from the approved batch · fill target 200 g ± 2 g (working assumption) · one batch sheet per melt · numbered bags and bottles.
Fill weight by batch — target 200 g, tolerance ±2 g (illustrative readings) 198 g 200 g 202 g B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12 Batch 7: 202.6 g — outside tolerance, investigate Each dot = average of the fills checked in that batch · shaded band = tolerance you set · figures are an illustration, not CSI data
A control chart of fill weights, one dot per batch, with the tolerance you set drawn as a band. The readings here are an illustration. Eleven batches sit inside 200 g ± 2 g, and batch 7 averages 202.6 g. Plotting each batch as you go shows a drift, for example a jug that has started pouring heavier, while there is still time to correct it, not after all 600 candles are packed.
Straight answer
I'm producing a large candle order in several batches — how do I keep fragrance strength, colour and fill weight identical from the first batch to the last?
By making every batch from the same written recipe, measured by weight, and checking it against references you set before batch 1. For 600 red 200 g candles in 12 batches of 50, the recipe per batch is 9,200 g of wax + 800 g of oil (8%) plus dye at the rate you settled on in testing. Dye doses aren't published, so follow the product page and test. Fragrance strength holds when both wax and oil are weighed every time, the oil goes in at the same temperature with the same stir time, and every batch cures equally long. A 200 g slip in the wax turns 8% into 8.16% or 7.84%. Colour holds when the dye comes from one order, is dosed by weight per kilo of wax, and each batch is compared against a reference chip from the approved batch. Fill holds when you tare every jar and check a sample from each batch against a target set in advance, such as 200 g ± 2 g. All of it goes on a batch sheet, one per melt, with bag and bottle numbers, weights, temperatures, fills and rejects.
One line: one recipe in grams, weighed every time, checked against a reference chip and a fill tolerance, and written on a sheet per batch.
Consistency starts with buying everything for the order at once, so every batch draws from the same stock. For 600 × 200 g Vanilla Bean candles that is 10 × 1 kg of oil (₹76,460.00) and 23 × 5 kg of Luxury Soy Wax Chunks (₹68,885.00), plus all the dye the order will need in one purchase.
See Vanilla Bean Fragrance Oil

One recipe, written per batch

A recipe written as "8%" leaves room for interpretation. A recipe written as "9,200 g wax, 800 g oil" doesn't.

The example is a wedding order of 600 red candles, 200 g each, in White Matte Glass Jars, scented with Vanilla Bean Fragrance Oil at 8% and poured in Luxury Soy Wax Chunks, rated up to 13% by the wax maker. It is coloured with Candle Dye Liquid Red. Production runs in 12 batches of 50 candles, each a 10 kg melt. The first job is to turn percentages into grams, per batch, and print them:

Per batch of 50 × 200 g · 8% load · dye rate is YOURS from testing (not published)
The batch recipe card
Ingredient Per candle Per batch (50) Whole order (12 batches) How it's measured
Luxury Soy Wax Chunks 184 g 9,200 g 110.4 kg (+ allowance) Weighed on the scale, per draw
Vanilla Bean Fragrance Oil 16 g 800 g 9.6 kg (+ allowance) Weighed into a jug, never poured "by eye"
Candle Dye Liquid Red — Your tested g per kg × 9.2 kg Your rate × 110.4 kg Weighed; the same bottle order for all batches
Eco Candle Wicks Thin C1 1 50 600 (+ spares) Counted; centred with a device
White Matte Glass Jar 1 50 600 (+ spares) Counted; tared before filling

Pin the card beside the melter. Every batch is weighed to it. If you change anything — the load, the dye rate, the pour temperature — you change the card, date it, and note the batch number where the change began. That one habit prevents most of the "why is batch 9 different" problems before they start. I Need 1,000 Identical Candles — Should I Buy All the Wax from One Batch to Reduce Production Variation? covers numbering the wax bags so that each batch sheet can record which bags it drew from.

Weigh the jug, not just the ingredient
Tare the empty pouring jug on the scale (₹354.00) before adding oil, and weigh the oil in the jug you will pour from. Oil clinging to a measuring cup that is then poured into another container is oil that never reaches the wax. A Candle Wax Pouring Jug costs ₹531.00.

Fragrance strength

Scent strength drifts between batches for three reasons: the actual load changes, the oil is handled differently, or the candles cure for different lengths of time. The first is pure arithmetic, and it is larger than most makers expect:

Batch of 10 kg candle · planned 9,200 g wax + 800 g oil · arithmetic
What small weighing errors do to an 8% load
What happened Wax Oil Actual load Oil per 200 g candle
As planned 9,200 g 800 g 8.00% 16.00 g
Wax over-weighed by 200 g 9,400 g 800 g 7.84% 15.69 g
Wax under-weighed by 200 g 9,000 g 800 g 8.16% 16.33 g
Oil over-poured by 50 g 9,200 g 850 g 8.46% 16.92 g
Oil short by 50 g (last of a bottle) 9,200 g 750 g 7.54% 15.08 g
Oil measured by volume, not weight (example: 5% short) 9,200 g 760 g 7.63% 15.26 g

Each of those errors is easy to make on a busy day. A bag weighed "about 9 kg", the last 50 g of a bottle that didn't quite make 800, a measuring jug read by volume. None of them is visible in the candle until someone burns it beside a candle from another batch. Weighing both the wax and the oil for every batch removes all of them. So does noting the oil bottle number on the batch sheet: if a batch needs topping up from a new bottle, weigh the top-up and write it down.

1
Weigh the wax for the batch9,200 g, from the bags recorded on the sheet. If you blend bags, weigh each draw.
2
Melt and bring it to your tested oil-addition temperatureThe temperature isn't published for this wax. Use the one you settled on in testing and check it with a pen thermometer (₹354.00). Write the reading on the sheet.
3
Weigh the oil into the jug800 g, from the numbered bottle. Record the bottle number and the weight.
4
Add and stir for a fixed timeUse the same stir time for every batch, for example two minutes with a bamboo stirring stick (5 for ₹118.00). The figure is a working assumption, but keeping it the same every time is the point.
5
Cure every batch the same length of timeBatch 1 shouldn't cure three weeks while batch 12 cures three days because the delivery date is close. Plan the schedule so the last batch gets the full cure. I Need to Produce 500 Candles in Seven Days — How Do I Calculate Whether My Current Melting Equipment, Moulds and Workspace Can Handle the Production Volume? covers the capacity side.
Argued against our own interest, plainly. When a late batch smells weaker, the reflex is to blame the oil and order more of it, or to raise the load. Usually the load was never 8% in that batch, or the cure was shorter. Selling you another kilo doesn't fix that. Check the batch sheet first. If the weights and the cure were identical and the difference is real, test the oil against your retained sample (I Need Several Kilograms of One Fragrance for a Corporate Order — Should I Test the Bulk Fragrance Batch Against My Original Sample Before Production?) and ask us on WhatsApp.

Colour

Colour is the first thing a client notices in a row of candles, and the easiest to drift a shade at a time.

Liquid dye is dosed in small amounts, and small amounts are where errors grow. Dye doses per kilo of wax aren't published in our data, so follow the product page, settle your own rate in testing, and hold it by weight rather than by drops. Drop size changes with the bottle, the angle and how full it is. Three habits keep the colour steady:

1
Buy all the dye for the order at onceCandle Dye Liquid Red is listed at 15 g for ₹236.00, 50 ml for ₹472.00 and 100 g for ₹900.00. Multiply your tested rate by the order's 110.4 kg of wax, add a margin, and buy that in one go.
2
Make a colour master (general practice)Some makers dissolve the whole order's dye into a measured quantity of wax once, cool it in a mould, and then add a fixed weight of that master to each batch. Weighing 100 g of master is more repeatable than counting drops. Test it before the order: the ratio is yours to set.
3
Keep a reference chipPour a little of the approved batch into a small mould, such as one cavity of a 40-cavity square mould (₹472.00), and label it "reference". After each batch sets, pour a chip from that batch beside it and compare them in daylight. Keep every batch's chip. At the end of the order, the row of chips is your record.

Two cautions. Wax colour changes as it cools and cures, so compare set chips with set chips, never a liquid batch with a solid reference. Dye can also interact with fragrance. That is a general-practice effect, and it is why the approved colour must be tested with the production oil at the production load. If the client is choosing the colour now, A Client Wants a Custom-Coloured Candle — Should I Finalise Fragrance, Colour, Wick and Wax Before Ordering 1,000 Jars? covers what to settle before ordering jars.

The CSI principle
Measure what you can weigh; compare what you can't.
Wax, oil, dye and fill are weighed against numbers on a card. Scent and colour are compared against a physical reference: the retained sample and the reference chip. Anything neither weighed nor compared will drift.

Fill weight

Fill weight is the easiest variable to control and the one clients notice first, because a lower fill line sits right next to a higher one. It also carries the scent: a 200 g candle at 8% holds 16 g of oil, a 195 g fill holds 15.60 g and a 205 g fill holds 16.40 g. Across 600 candles, a 5 g average overfill uses 3 kg of extra candle, which is ₹3,488.28 of wax and oil at list rates.

1
Set the target and tolerance before batch 1For example, 200 g ± 2 g, measured as candle weight with the jar tared. The tolerance is a working assumption. Choose one your pouring can hold.
2
Tare every jarJars vary slightly in weight, so a gross-weight target is not a fill target. Tare each jar on the scale as you pour, or tare a sample of jars and use their average if you pour by jug.
3
Check a sample from each batchWeigh, say, every tenth candle (working assumption) and write the weights on the batch sheet. Average them, and mark the average on the control chart.
4
Act on a drift, not only on a failureThree batches in a row edging upward is a signal, even if all three are inside the tolerance. It usually points to the jug, the pouring hand or the top-up routine.
Topping up by eye. Soy container candles often need a second, small pour to fill a sinkhole. Done by eye, it adds anything from 2 g to 8 g, and the difference shows up in the fill line and in the batch's average. Fix: weigh the top-up too. Tare the candle after the first pour, top up to the target weight, and record how much the top-up took.

The batch sheet

Print one per batch. It takes two minutes to fill in, and it is the only way to answer "what was different about batch 7?" a week later.

Notes

With 12 sheets you can see the order as a whole. The control chart above is simply the fill averages from the sheets, plotted in order. Similar charts for top-up grams and reject counts show a drift the same way. Keep the sheets with the retained samples until the client accepts delivery.

Why trust this guide

CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. When a batch comes out weaker or paler, the convenient advice for us is "buy more oil" or "buy a stronger dye". This page points you to your scale and your batch sheet first, because that is where most batch-to-batch drift starts.

Oil and wax prices are CSI live pricing, pulled 24 September 2026. Dye, jug, stirring-stick and mould prices were pulled 24–25 September 2026. Scale, thermometer, wick and jar prices are Blog 760's, verified 10 September 2026. Load-error figures are arithmetic on the batch recipe.

Dye doses, oil-addition and pour temperatures, cure times and melter throughput aren't published in our data. Use your own tested figures. The fill tolerance, stir time, sampling rate and control-chart readings are working assumptions or illustrations. The colour-master method is general practice.

Frequently asked questions

Why do my candles smell different from batch to batch?
Most often because the real load changed: wax or oil not weighed every time, a short bottle, or oil measured by volume. A 200 g error in a 9.2 kg wax batch moves 8% to 8.16% or 7.84%. Different cure times are the next most common cause. Weigh everything, and cure every batch equally.
How do I make candle colour consistent?
Buy all the dye for the order at once, dose it by weight per kilo of wax at your tested rate (doses aren't published — follow the product page), consider a colour master made once for the whole order, and compare every batch with a reference chip from the approved batch, set against set.
What is a good fill weight tolerance for candles?
There is no published standard. Choose one your process can hold and write it down before batch 1. This page uses 200 g ± 2 g as a working example. Tare every jar, weigh a sample from each batch, and investigate any batch average outside the band.
What should a candle batch record include?
Date, who poured, wax bag and oil bottle numbers, weights of wax, oil and dye, temperatures at oil addition and pour, stir time, room temperature, candles poured, top-ups, fill checks, colour check, rejects and cure dates. The template is in the batch sheet section.
How much fragrance oil per batch of 50 candles?
For 50 × 200 g candles at 8%: 10 kg of candle, so 800 g of oil and 9,200 g of wax. Weigh both. Vanilla Bean at the 1 kg rate is ₹6,116.80 of oil per batch.
Should I buy all materials before starting a multi-batch order?
Yes. Buying the whole order's wax, oil and dye in one purchase means every batch draws from the same stock, which removes a source of variation. Number the bags and bottles, and record them on each batch sheet. See I Need 1,000 Identical Candles — Should I Buy All the Wax from One Batch to Reduce Production Variation? for the wax side.
