Should I Reserve Specific Production Days Exclusively for a Large Candle Order Instead of Mixing It into Normal Production?

The order, the website and the melter, as numbers

Scents are ranked by weight: fresh and aquatic light (rank 1), florals middle (2), woods, gourmands and vanilla heavy (3). The ranking is a practical judgement about carry-over, not a chemical one; what matters is that a trace of a heavy scent is noticeable in a light one, and a trace of a light scent in a heavy one usually is not.

The schedule in each plan is filled day by day: add the next melt if its changeover plus its 100-minute cycle still fits inside 408 minutes, otherwise start a new day. That simple rule is enough to show the difference; your real day has more in it.

What a changeover really costs

Time one honestly before you decide anything. Empty the melter, deal with the heel, wash or wipe the tank, swap pitchers, take a fresh stirrer, clear the bench of the last scent's labels, and smell the empty tank before the next oil goes in. Going from heavy to light takes longer because "clean enough" is decided by your nose, not your eyes.

The heel is easy to forget. At 0.3 kg per change and a Blue Ocean mix worth about ₹982.52 a kilo at CSI bulk prices (92% CSI 468 at ₹637.00 a kilo plus 8% oil at ₹4.96 a gram), each change throws away roughly ₹294.76 of scented wax. Some makers pour heels into seconds or test candles; on a corporate order they rarely become saleable.

The same 30 melts, scheduled two ways

The diagram above shows both schedules melt by melt. Here they are as a capacity table.

Read the minutes first: 390 minutes is 96% of a working day spent washing in the mixed plan, against 60 blocked. That pushes most mixed days down to three melts, while blocked corporate days fit four. These are melter-side numbers: whether your hands can wick, pour and pack about 183 candles on a block day is the station check in the maximum-capacity post, and if they can't, the block simply runs more days at the same low changeover count. One day saved on 30 melts sounds small; on a 5,000-candle order it is the difference between one melter and two.

Then read the quality rows, because they are why most experienced makers block even when time is not tight. In the mixed plan 6 Blue Ocean melts go into a tank that has just held a heavier scent, and on 9 days both corporate labels are on the bench together. Each of those is a chance for a wrong candle in a client's carton. Blocked, the first is zero by design and the second happens once, on the day one block ends and the next begins: clear the bench of Blue Ocean labels before the first Cinnamon Vanilla melt is poured.

Lots, traceability and focus

Lot consistency. 10.5 kg of Blue Ocean is eleven bottles, and CSI does not promise they share one lot. In a block you open them in sequence and, if a second lot appears, it starts at a melt you can name. Mixed in, lots end up spread across days next to website melts of the same oil, and if the second lot smells different you cannot say which corporate candles have it. If a new lot does arrive, compare it with the first before it goes in the melter: cold sniff, colour in wax, a short burn. The new-lot-mid-run post covers what to check.

Traceability. Number the melts BO-01 to BO-13 and CV-01 to CV-9, write the oil lot, wax lot, add and pour temperatures and pour time against each, and mark each candle's base or carton with its melt number. Blocks make this a list; mixed days make it a puzzle. When a client reports one weak candle in a carton of 50, the melt number tells you whether it was one melt or a whole lot.

Focus. One scent, one label, one carton spec on the bench. People get faster at a repeated task within a day, and mistakes cluster at switches. That is judgement, not data, but every maker who has found a Cinnamon Vanilla label on a Blue Ocean candle believes it.

How to lay out the blocks

The decision rule. Dedicate blocks when the corporate order uses a scent, colour or jar you do not pour every day, or when mixing would add more than about one changeover per day (judgement). Mix it in only when the corporate candle is an existing website candle: same wax, oil, load, wick and jar, where "mixing in" just means bigger batches of a scent you were going to pour anyway. In the worked example the settling number is 330 minutes saved, about 0.81 melter-days, on 30 melts, with heavy-to-light washes falling from 6 to none.

The block kit: materials staged per block

The purchase is ordinary; what changes is that each block gets its own staged kit, so the melt sheet, lot numbers and materials line up. The sheet assumes your proven formula is Premium Coconut Soy Wax CSI 468, 8% load and an Eco C2 wick in your own 200 g jar.

₹218.98 per saleable candle is CSI materials only, buffers included, and excludes your jars, labels, cartons, labour, freight, GST and marketing. Oil per candle is ₹79.36 for Blue Ocean and ₹72.80 for Cinnamon Vanilla at the 1 kg price. Twelve 10 kg wax bags opened for block 1 leave 2.921 kg that carries into block 2; that is fine if both are the same wax lot, and worth writing on the melt sheet if not.

Argued against our own interest, twice. Blue Ocean's 100 g bottle is ₹4.95 a gram against ₹4.96 for the 1 kg, so 10 × 1 kg + 2 × 100 g (₹50,550.00, 19.2 g spare) is the cheapest way to cover 10.1808 kg; we suggest the 500 g instead (₹52,038.00) because 19.2 g of spare oil is too thin for a 630-candle block. And CSI 468 costs ₹637.00 a kilo whether you buy 5 kg or 10 kg bags, so nothing is saved by buying bigger; split deliveries by block if that helps your cash. Whether to buy everything up front or in tranches is the split-purchasing post; keeping the corporate stock away from website production is the reserved-materials post.

What to buy for block production

Six items, chosen on page statements, price and stock on 7 October 2026. CSI publishes no burn or throw data, so nothing here is ranked on performance. Two of the six are tools whose whole job is to make changeovers shorter.

Skip: a second melter "so I can keep one for corporate and one for website" before you have tried blocks: the maths above says one melter run in blocks is usually enough at this size, and a second tank doubles the cleaning. Skip the 20 kgs unit for the same reason unless your blocks are long. Argued against our own interest: buy the corporate oil only after the client has signed the scent split. A block plan for an unsigned split is a plan for 17.5 kg of oil you may not need.
