I Want to Launch Five Luxury Candle Fragrances Using One Jar — Can I Use the Same Wax and Wick for All Five or Should Each Fragrance Be Tested Separately?

What five scents can share, and why that is worth doing

Start with what a fragrance oil is not responsible for. It does not decide the diameter of your melt pool — the jar does. It does not decide the pour temperature — the wax does. It does not decide the cure window you publish on your care card, or the weight your customer reads on the label. Those are container and wax decisions, and once they are made they are made for the whole collection.

That is why a five-scent launch on one jar is a cheaper project than five separate candles. The Clear Glass Jar with Golden Lid page states a 150 g fill capacity, 8 cm height, 7 cm outer diameter and approximately 6.5 cm base diameter, and that it is safe for hot pour up to 85°C. Those four stated figures are the only fixed geometry in the project, and every one of your five tests inherits them.

Read the right-hand column as a priority order. The expensive reversals sit at the top, which is exactly why the container and the wax get decided first and then left alone. The cheap reversals sit at the bottom, which is why dye is a late decision and a wick is something you buy twenty of, not five hundred. The full argument for that sequence is the subject of the decision-order guide.

Five oils, five stated ceilings — and one rule

Here is the thing that makes a shared load unsafe as an assumption. Fragrance oil pages do not all say the same thing, and CSI does not pretend they do. Below are the five oils in this worked example with the candle position each page actually publishes, alongside the flash point where the page states a measured one. Where a page says nothing, the table says nothing — silence is not permission.

What the oil actually changes — the honest answer

Two things move when you change the fragrance, and both of them land on the wick.

The first is the practical load. Your target load might be 8% on all five, but the number you can actually run is capped by the lower of two stated ceilings, and those ceilings differ between oils. On the set above they happen to agree at 10%; swap Bergamot Amber for an oil whose page states 6–8% for soy and your practical maximum on that one scent drops, which changes the grams of oil in the jar, which changes what the flame is drawing through. A collection where four scents run at 9% and one runs at 7% is completely normal and completely fine — as long as you know which is which and your labels do not promise otherwise.

The second is burn behaviour, and this is the part makers skip. Fragrance oil is not an inert passenger. It is dissolved in the wax and it goes up the wick with it. Different oils are different mixtures of molecules at different weights, so the fuel arriving at the flame is not the same fuel between two jars that are otherwise identical. That is why a wick that gave you a clean, full pool in 2–3 hours on rose can mushroom on vanilla oud, or sit in a shallow pool and tunnel on vetiver, in the same 7 cm jar. The mechanism is set out in the mushrooming and wick-sizing guide and from the other direction in why a candle tunnels even with the correct wick.

The 20-jar, five-scent grid

The grid changes one thing at a time and nothing else. Scent runs across the columns, wick down the rows, and the two jars in each cell exist so that a single odd result cannot decide anything. Everything else — jar, wax, load, add temperature, pour temperature, cure length — is written down once at the top of the sheet and held.

The five oils, costed at 50 g

Three of the five are worth looking at closely, because they bracket the range you are likely to build: a woody single note with a published flash point and a no-discolouration position, the cheapest per gram of the five, and the one that costs most per jar. Each card shows every listed size, the price per 100 g, and how many 150 g jars at 8% of wax weight each pack would fill.

The remaining two — Bergamot Amber at ₹280 for 50 g and Vetiver at ₹354 — round the set out with a bright citrus-amber opening and a dry earthy base. Both publish a 0% vanillin position; Vetiver publishes a 206°C flash point. Note that Vetiver's 1 kg size is currently sold out, so if it wins the grid, plan its production quantity from the 500 g pack and ask about larger volumes rather than assuming a kilo is available. For a wider shortlist, five fragrance oils for a luxury collection is the companion read.

The whole grid, line by line

This is the complete purchase for twenty test jars across five fragrances, with the reason each line is the size it is. Two of the lines — the scale and the thermometer — are bought once for every batch you will ever pour, so they sit below the materials subtotal.

Two figures in that table are worth keeping. ₹276.48 a test jar is what one data point costs you in this jar with this wax, and it is the number to hold against the alternative: a hundred candles poured on an untested wick, at ₹94.40 of glass each, is ₹9,440 of container alone that you cannot unbuy. ₹1,105.92 a fragrance is the real unit, because that is the decision you are buying — not a candle, a verdict on one scent.

What to buy once the grid passes — and what not to

Now the arithmetic gets easy, because the grid told you the two things you did not know. Suppose the verdicts come back: sandalwood, rose and bergamot amber on C1; vanilla oud and vetiver on C2; all five at 9% except vanilla oud, which was cleaner at 8%. You order wicks in the split the grid gave you, not in equal quantities, and you order oil in proportion to how you intend to sell the five — which is a commercial judgement, not a test result.

Note the last oil row carefully, because the pack ladder is not the same shape on every listing. On British Rose the price per gram falls from ₹4.248 at 50 g to ₹3.422 at 100 g and ₹3.186 at 500 g, so a bigger bottle genuinely saves money. On Sandalwood it is ₹5.0268 a gram at 100 g, 500 g and 1 kg alike — completely flat, so buy the quantity you will use inside a reasonable window and no more. Check each oil's ladder before you round up. The scale version of this arithmetic is in the 500-a-month pack-size guide, and the first-launch version in the 100-candle launch guide.
