I Want to Test 6%, 8% and 10% Fragrance Load as a Beginner — How Much Wax and Fragrance Do I Need for Each Test Without Wasting a Full Kilogram?

Why this test is smaller than you think

A load ladder is one of the cheapest experiments in candle making, and beginners routinely over-buy for it because they picture the test in the vessel they eventually want to sell. That instinct is backwards. The purpose of a load test is to learn how a particular oil behaves at three concentrations in a particular wax — and concentration does not care how big the candle is. A 10% tin and a 10% jar have the same ratio of oil to wax. The ratio is the finding; the vessel is only the container it travels in.

What the vessel does change is the bill. Because the wax share of a candle is 90–94% of its weight at these loads, every gram you add to the finished candle is almost a gram of extra wax, multiplied by six. Going from an 85 g tin to a 200 g candle adds 115 g per candle, or 690 g across the ladder — which is the difference between a 500 g pack and a full kilogram with a second pack alongside it.

There is a second reason to keep this test small, and it has nothing to do with money. A load ladder is only readable if the three arms are otherwise identical, and identical is easier at small volumes: one melt, one thermometer reading, one room, one afternoon. Six 85 g tins can be poured in a single session from a single melt split three ways. Six 200 g candles usually cannot, so the arms drift apart in cooling speed and pour temperature — and then you are comparing pour days, not loads.

The three loads, gram by gram

Here is the whole test as numbers. Load is calculated as a share of the finished candle, which is this series' convention: an 85 g candle at 8% is 78.2 g of wax and 6.8 g of oil. Some wax pages instead phrase their range as a share of total wax weight; on an 85 g tin that convention gives 78.70 g of wax and 6.30 g of oil at 8%, a difference of half a gram. Pick one convention, write it at the top of your log, and never mix them mid-test — a swapped convention looks exactly like a mis-weighing.

Vessel size is the whole saving

The question in the title is really a question about vessels, so here it is answered directly. Below is the identical three-point ladder — two candles per arm, six candles, same loads — priced in four candle sizes. Only the finished weight changes.

Read the bottom row against the top. Pouring 200 g candles more than doubles the materials consumed — ₹981.89 against ₹417.30 — and forces you into a second wax pack and a 100 gm bottle, for exactly the same three loads on exactly the same oil. That is the wasted kilogram in the title, and it is entirely avoidable. It is also worth noticing what the gap is made of: of the ₹564.59 of extra materials the 200 g version burns through, ₹330.10 is wax and ₹234.49 is oil — you would be spending it on candle mass, not on information.

One honest note about the tins themselves. The Golden Aluminium Tin page states a fill capacity of about 85 g and no dimensions, and it suggests pairing the tin with "C1 or C2 wooden wicks" — C1 and C2 are in fact the two Eco Candle Wick sizes, not wooden wicks, so read that line as a pointer to the Eco range. Metal conducts heat readily, so a tin will feel hotter on the outside than glass at the same burn; that is normal, it applies equally to all six of your candles, and it is one more reason never to leave any burning candle unattended.

The scale problem nobody mentions

This is the part of a small-vessel load test that goes wrong, and it is worth more than the money you saved on wax. The arms of an 85 g ladder are separated by 1.7 g of oil. A kitchen scale that displays whole grams can be up to half a gram out on any single reading, and you take two readings per candle — the wax and the oil. Half a gram of oil on an 85 g candle is 0.59 of a percentage point. In the worst case your "6%" tin is actually 6.6% and your "8%" tin is 7.4%, and the gap you set out to measure has shrunk from two points to less than one.

Weighing a batch of two halves the relative error for free, because the same absolute error is spread over twice the material. That is the single most useful habit in this whole test, and it costs nothing. The Candle Making Weighing Scale at ₹354 states that it shows measurements in grams or ounces; the page does not state a resolution, so check what your unit actually displays before you rely on it for a 5.1 g reading, and prefer batch weighing regardless.

What to buy for a three-point ladder

Four items, none of them a commitment. Each card gives every listed pack size, the price per kilo or per 100 g, and how many 85 g candles at 8% each pack covers.

Ordered versus consumed

Two numbers matter when you are trying not to waste anything: what leaves your account, and what actually ends up inside the six candles. Both are below, with the leftovers named rather than hidden.

Per tin, the consumed materials come to ₹105.45 at the 8% arm: 78.2 g of wax at ₹0.52 a gram is ₹40.66, 6.8 g of oil at ₹4.248 a gram is ₹28.89, the tin is ₹30 and the wick is ₹5.90. The 6% tin is slightly cheaper and the 10% tin slightly dearer, because oil costs about eight times what this wax does per gram — which is itself a finding worth carrying forward. If 8% and 10% perform the same after cure, the 8% formula is the one to sell.

Running the six-tin ladder

One session, three batches, six tins. The order of operations below exists to keep the arms identical in everything except load — which is the only thing this test is allowed to measure.
