I Want to Make a 200 g Scented Soy Candle — How Do I Work Backwards From the Finished Candle Size to Choose the Jar, Wax Quantity, Fragrance Amount and Wick?

The six-step chain, in order

A candle recipe has one free variable and five derived ones. The free variable is the finished weight, because that is a product and pricing decision — what your customer holds, what it costs, what it burns for. Everything else follows from it in a fixed order, and each step depends only on the steps above it. Reverse any two and you will buy something twice.

Step 1 — the jar that actually holds 200 g

Start here rather than with the wax, because this is the step with a genuine catch, and nobody warns beginners about it. Candle jars are described in two different units. Some pages state a fill weight in grams, which is exactly what your recipe needs. Others state a capacity in millilitres, which is a volume — useful for a jam jar, not directly usable for a wax recipe.

The conversion is not one-to-one, and you should not invent a factor for it. What you can rely on is the direction: wax is lighter than water, so a jar that holds 200 ml of water will hold less than 200 g of wax filled to the same level — and you will be filling to a line below the rim, not to the brim, which takes a little more off again. The only trustworthy number is the one you measure. Pour one candle in the jar you have chosen, weigh what went in, and that is the fill weight for every batch afterwards.

So what do you actually buy for a 200 g candle? Three honest routes. One: take a 200 ml jar — the Salsa at ₹29.50 in hundreds is the cheapest glass in this class — pour one, weigh it, and accept whatever number comes out as your candle's true finished weight. Two: move the target to a jar that publishes a weight near yours — the Ceramic Jar states "Fill Weight: 180 grams" at ₹129.80, which is a 180 g candle with no measuring at all: 165.6 g of wax and 14.4 g of oil at 8%. Three: change the target. A 150 g candle in a jar that states 150 g is a cleaner product than a 200 g candle in a jar that has to be measured, and the maths is identical — 138 g of wax and 12 g of oil.

Step 2 — splitting 200 g into wax and oil

Fragrance load is a percentage of the finished candle, not an amount added on top of the wax. That single convention decides every quantity in this guide, and getting it the wrong way round is the most common arithmetic error in beginner candle making.

Worth knowing: the other convention exists too. The Luxury Soy Wax Chunks page phrases its recommendation as "8% to 13% of total wax weight", which is a share of the wax rather than of the finished candle. The difference at these percentages is small — 8% of 184 g is 14.7 g against 16 g — but it is real, so pick one convention, state it on your recipe line, and stay with it. Everything in this guide is a share of the finished candle, the same convention CSI's own guides use.

Two practical notes on choosing between those rows. First, the ceiling that binds you is the lower of your wax's stated figure and your oil's stated figure — Sandalwood states "Up to 10% for soy wax", so a 13% wax does not give you 13% with that oil. Second, moving up the table costs money quickly: at ₹5.0268 a gram, Sandalwood in one 200 g candle is ₹80.43 at 8% and ₹130.70 at 13%. Raising the load is the most expensive lever on the bench and, as the throw guide sets out, rarely the most effective one.

Step 3 — wax quantity, per candle and per pack

184 g per candle is the number you multiply. What trips people is the allowance: wax stays in the jug, on the spatula and in the top-up you do when the surface sinks. Plan on 3–5% more than the arithmetic — an allowance, not a specification — and the pack you need changes at the margin.

Step 4 — the fragrance amount, and what it costs

16 g per candle is a small number that dominates the cost sheet. Across CSI's single-note candle oils, 16 g ranges from about ₹34 to over ₹100, which is a wider spread than the entire soy wax range contributes to the same candle. This is the line to get right before you buy a bottle size.

Every row makes six candles from 100 g, because 6 × 16 g is 96 g — which makes the 100 gm bottle the natural partner for a six-candle plan and the 15 gm size almost useless for pouring: 15 g is under one candle's worth. Keep 15 gm bottles for smelling and shortlisting, and buy 100 gm of whatever survives that. At the other end, a 500 gm bottle covers about 31 candles at 8% and lowers the per-gram price on most oils — Lavender goes from ₹5.40 to ₹5.24 a gram, Citrus Lemon from ₹3 to ₹2.84.

Step 5 — the wick comes from the diameter, not the 200 g

A wick's work is measured across the candle, not down it. Two 200 g candles — one tall and narrow, one short and wide — need different wicks, because the wick has to keep a pool of molten wax reaching the glass and the distance to the glass is the diameter. This is why "what wick for 200 g?" is unanswerable and why a wick recommendation copied from a recipe with a different jar usually disappoints.

CSI's wick pages are honest about this, which means most of them state no diameter range at all. One jar page, unusually, states a pairing instead: the 200 ml Salsa Amber jar says "Pairs well with C2 Eco Wicks." Treat that as a starting bracket rather than a final answer — it is the supplier's suggestion for that glass, not a test of your wax, your oil and your load.

Step 6 — three costed builds and the batch ladder

Now the whole chain, priced. Three real builds of the same 200 g candle at 8%, using live CSI listings. The only differences are the wax, the oil and the jar — the wick, the sticker and the load are identical.

One observation worth carrying into your pricing: across these three builds the oil is the largest single line in two of them, and the spread between the cheapest and dearest candle — ₹97.08 — is almost entirely oil and wax choice, not jar choice. The jar is the line beginners agonise over and the oil is the line that actually moves the cost.

The four products this build needs

One jar, one wax, one oil, one wick — the whole 200 g chain in four listings, each with every pack size and what it works out to per candle.
