I Want to Make 60 × 300 g Luxury Candles — How Much Wax Should I Buy When My Finished Fill Weight Includes Both Wax and Fragrance Oil?

Your 300 g already includes the oil

A luxury candle sold as "300 g" is a 300 g finished candle: wax and fragrance together, as the customer weighs it. CSI writes fragrance load as a share of that finished weight, so the split is one multiplication: at an 8% working load, oil = 300 × 0.08 = 24 g and wax = 300 × 0.92 = 276 g. The wax per candle is not 300 g, and the order is not 60 × 300 g of wax. It is 60 × 276 g = 16,560 g of wax and 60 × 24 g = 1,440 g of oil, before any allowance.

The right-hand column is the mistake in one line: ordering 300 g of wax per candle over-buys exactly the oil weight, every time — 1,440 g at 8%, 1,800 g at 10%. Worse, if you pour it as written, each candle becomes 324 g and either overfills the jar or sits above the line you designed. The fix is not a smaller allowance; it is splitting W before anything else. The wax-weight-per-candle post shows the same split for a 200 g jar, and the oud post shows the overfill it prevents at 10%.

Which 300 g? Candle weight versus jar capacity

There is a second "300 g" that causes trouble: a jar described as "300 g" or "300 ml". That is usually the jar's capacity to the brim, measured with water. Solid soy wax is lighter than water; at a labelled approximate 0.86–0.90 g per ml, a jar that holds 300 ml of water holds only about 258 g–270 g of candle filled right to the brim — and a candle is never filled to the brim. A 300 g candle will not fit in it. CSI does not list a jar with a published fill at this size, so the jar here is yours, and its real fill is something only a weighed test pour can tell you.

The order for 60 candles

With W fixed at 300 g and an 8% working load, the stack is: six test candles (three on a single Eco Thick C2, three on two Eco Thin C1 — a 300 g candle in a wide jar may need two wicks, and CSI publishes no wick-per-diameter chart), a 3% reject allowance on wax, oil, wicks and stickers, and 5% pour loss on wax and oil. Jars are your own, so breakage appears only as a count (68 jars for 66 candles at 2%).

That is ₹312.06 of CSI materials per saleable candle with a single wick, before the jar. A double wick doubles the wick and sticker lines but leaves wax and oil untouched — the candle is still 300 g at 8%. Natural Soy Pearl is used because the wax line is large (nearly 20 kg) and it is the only CSI soy wax with a real bulk break: ₹450.00 a kilo at 1 kg, ₹424.80 from 5 kg. Its page publishes no fragrance ceiling, melt point or pour temperature, so 8% is a labelled starting point — ask CSI on WhatsApp for the wax maker's stated maximum before planning 10% or more.

Saffron Cedarwood: where the 500 g bottle wins

Saffron Cedarwood Fragrance Oil is a reasonable luxury example because its price ladder is unusual. Per gram it is ₹6.92 at 15 g, ₹7.08 at 50 g, ₹6.96 at 100 g, ₹5.17 at 500 g and ₹6.87 at 1 kg. The 500 g bottle is the cheapest per gram on the listing — cheaper than the kilo — so the order is built from 500 g bottles, with the remainder from small bottles. CSI publishes no throw data, composition or IFRA percentage for it here; check the product page or ask for the IFRA certificate on WhatsApp.

The cheapest cover lands within a gram of the need, which is tight: it assumes your pour loss really is 5% and your rejects 3%. If either runs high, the last candle is short. Four 500 g bottles cost ₹1,087.96 more and leave 285 g — about 12 candles' worth — as a cushion or the start of the next run. Two 1 kg bottles are the worst of both: dearer per gram and ₹3,398.40 more than four 500 g for the same 2 kg.

What makes it luxury is not the wax maths

A luxury candle usually means a heavier jar, a lid, a box and a higher load or a more complex fragrance — none of which changes the rule on this page. Every one of those choices changes W, L or the jar, and the order follows from them. What does change is the cost of a mistake: a 300 g candle in a premium jar is the most expensive candle to remake, so the test candles and the reject allowance earn their place. Keep the luxury lines — jar, lid, box, label — as your own quotes outside the CSI subtotal so you can see exactly what the candle costs to fill.
