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?
Share
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.
One recipe, written per batch
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:
| 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.
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:
| 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.
Colour
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:
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.
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.
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.
| Field | Batch __ (fill in) |
|---|---|
| Date · start and finish time · poured by | |
| Wax bags drawn from (numbers) · weight from each | |
| Oil bottle number(s) · oil weight added | Target: 800 g |
| Dye (or colour master) weight · dye bottle number | Target: your tested rate |
| Temperature at oil addition · at pour | Your tested temperatures |
| Stir time | e.g. 2 minutes (working assumption) |
| Room temperature · cooling shelf used | |
| Candles poured · top-ups (g) | Target: 50 |
| Fill checks (every 10th candle) · average | Target: 200 g ± 2 g |
| Colour chip vs reference: match / slight / no match | |
| Rejects (count and reason) | |
| Cure start date · cure end date | Same length for every batch |
| 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.

When the order is delivered, keep the batch sheets, the chips and the retained samples together. If the client reorders next season, they are the specification.

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.
