I Need 1,000 Fragranced Mould Candles — How Do I Calculate Wax and Fragrance When Each Candle Loses a Small Amount During Trimming and Finishing?

Poured weight vs finished weight

Most mould candles are finished by hand. The base is levelled so the candle stands straight, the mould seam is shaved, and the wick end is cleaned and trimmed. Each step removes a few grams of scented wax. In our example it is 6 g from a 180 g candle, a labelled working figure. Weigh your own before and after trimming. The customer's candle weighs 180 g, and 186 g went into the mould. The question is which weight to multiply.

The load is the same in every row, because trimming removes a slice of an evenly mixed candle. It does not strip out oil selectively. So there is nothing wrong with the finished candle's fragrance. What goes wrong is the purchase. 0.48 g a candle sounds like nothing, but across 1,026 pours it is 492.48 g of fragrance oil, about ₹2,615.07 of Cinnamon at the kilo rate, all of it in a bin of shavings. The same logic holds for any mould candle with finishing loss, whatever the shape.

Building the 1,000-candle order

With the per-pour figure settled, the order follows the usual steps, in the usual sequence. Failed releases and test pours are counted in candles. The pour weight includes the trim. Pour loss comes last. All three rates are labelled working assumptions.

Scented trimmings: remelt or write off

Clean trimmings are a scented, correctly loaded batch of wax. Remelting them into the next pour is common practice, and it recovers most of the oil and wax. Keep them clean and sorted by scent and colour, and add them to a batch of the same formula. Test that the remelted batch still meets your scent standard, because reheating can dull some fragrances, and we have no measured figure for that. Here are both plans. We take 90% of the trim as recoverable, a labelled assumption for dust, floor drops and the last batch's trim, which has nowhere to go.

Remelting saves about ₹5,572.40 on this run, oil and wax together. That is worth a clean bin by the trimming bench. For a first run of a new design, though, buy on the written-off plan. You do not yet know how clean your trimmings will be, or whether the remelt passes your scent check. Use the recovered wax to cut the next order, not this one. Coloured trimmings go back only into the same colour, and multi-scent ranges need one bin per scent.

Load sensitivity with no published ceiling

CSI publishes no fragrance ceiling for Soy Pillar Wax. That is the product's own figure to check, on the product page or by asking on WhatsApp. Freestanding candles have no jar to hold seeping oil, so a load that works in a container can show as a greasy surface on a pillar. Test before you scale. Here is the same order at three labelled test loads:

Each two-point step moves the oil by about 3.9 kg and the oil bill by about ₹21,000 at Cinnamon's listed prices. The wax moves the other way, but at ₹0.60 a gram it barely registers. In a scented mould-candle order, load is the biggest cost decision. Set it by testing, not by the highest figure a forum mentions. The trim scales with the load too: at 10%, each 6 g trim carries 0.6 g of oil.

The priced order

With Sandalwood instead, the oil line is 15 × 1 kg + 1 × 500 g + 2 × 100 g + 2 × 15 g for ₹79,107.20. At 15 kilo bottles of one oil, this order is well past the point where a WhatsApp quote makes sense. Ask about supply in larger units and whether the whole quantity can come from one batch. A consistent scent across 1,000 candles matters more than a few rupees. Ask for the IFRA certificate and MSDS at the same time: no per-oil IFRA figure is published in our data. Wick size per mould is not published, and the 12 cm per pour is a labelled working length. Moulds, packaging, labour and freight are extra.
