Performance Testing × 30 Days
Weight tells you life. Blind scores tell you scent. Photographs tell you what the reeds are doing. A thermometer tells you what the room did to all three. Put them on one sheet, keep a control in the same room, and pass a formula only when every line passes.
13 weighings
on days 0, 1, 2, 3, 5, 7, 10, 14, 17, 21, 24, 28, 30 — plus 5 blind scores, 3 reed photo sets, 4 clarity checks and a daily min/max temperature
Quick answers — read this first
What should I measure? Four things: bottle weight with reeds in, blind room score, reed condition (photographed and graded) and room min/max temperature — plus clarity.

How often? Weigh on days 0, 1, 2, 3, 5, 7, 10, 14, 17, 21, 24, 28, 30; score on days 3, 7, 14, 21, 30; photograph reeds on days 0, 14, 30; temperature daily.

How many bottles? 3 per formula for a decision test, plus one capped no-reed bottle to check the scale and caps.

What does it cost? ₹4,320.00 in CSI materials for two formulas (₹4,674.00 with a scale). See the kit.
The short answer
Answer: Weigh each bottle with reeds in on a fixed schedule, score the room blind on a written house scale, photograph and grade the reed tops, check clarity against white and black cards, and log room min/max temperature daily — for 30 days, against a control in the same room.
Maths: Interval g/day = weight lost ÷ days. Liquid left = reading − empty bottle − dry reeds − liquid held in reeds. Projected life = liquid left ÷ recent g/day.
Pass: Scent held from day 14 to 30, life on target, reeds grade 2 or better, liquid clear at every check, three bottles consistent — all labelled lines you set before day 0.

Straight answer
How do I test reed diffuser performance over 30 days using liquid weight loss, fragrance intensity, reed condition and room temperature?
Run the formula you intend to sell against a control in one room, and record four things on one sheet: bottle weight with reeds in, a blind room score, the state of the reed tops, and the room's daily min/max temperature — plus a clarity check. Use 3 bottles per formula and one capped no-reed bottle to check the scale and caps. Weigh on days 0, 1, 2, 3, 5, 7, 10, 14, 17, 21, 24, 28, 30, same time of day, cap off; score blind on days 3, 7, 14, 21, 30, one bottle at a time; photograph reed tops against a white card on days 0, 14, 30 and grade them; check the liquid against white and black cards on days 0, 7, 14, 30. Interval g/day = weight lost ÷ days; projected life = liquid left ÷ recent g/day, from day 2. Do not correct for temperature — record it, and let the control meet the same weather. Pass only when scent, life, reeds and clarity all pass the lines you wrote before day 0. With Lift and Softness and Jasmine, CSI materials cost ₹4,320.00.
One line: four measurements, one sheet, one room, a control beside it — and no changes after day 0.
A 30-day test needs four measurements on one sheet: weight, room score, reed condition and room temperature. The example compares Lift Base and Softness Base — both pages name jasmine — with Jasmine at 20% in seven 120 ml Gold bottles: ₹4,320.00 in CSI materials, or ₹4,674.00 with a scale.

What a 30-day test has to prove

Fourteen days tells you which way a formula is heading. Thirty days tells you whether it gets there — and what it looks like when it does.

Every shorter test in this section screens one variable: reed count, flip behaviour, reed size, season, consumption, clarity. A 30-day test is different. It is the confirmation you run on the formula you intend to sell, against a control, before you print a life claim or send a bottle to a corporate client. It has to answer four questions together: does the room score hold over the month, does the bottle lose liquid at a rate that delivers the life you want, what state are the reeds in by the end, and is the liquid still clear. A formula that wins three of the four has not passed.

Room temperature runs underneath all four. A passive diffuser responds to its room, and a month can include warm days, cool nights, a monsoon spell or the first cold week of winter. You do not correct for temperature with a formula — CSI publishes no temperature behaviour for any base, and no simple correction is reliable — you record it, and you keep a control bottle in the same room so that both formulas meet the same weather. Temperature changes the absolute numbers; the control keeps the comparison fair.

The example is a two-formula comparison because that is the most common reason to run 30 days: two candidate bases for one oil. Lift Base's page lists jasmine among its florals; Softness Base's lists jasmine among its soft florals. Both are ₹1,099.00 for 500 ml. Neither page is evidence about how jasmine will behave in it, and CSI publishes no diffuser throw, evaporation or longevity data for any base, oil or reed. Comparing two bases on evaporation, throw, clarity, reed compatibility and cost sets out the comparison logic; this page is the measurement protocol behind it.

Four measurements · each with its own scale · all on one sheet
What you measure, how, and why
Measurement How Unit or scale What it proves
Liquid weight loss Bottle weighed with reeds in, cap off, same scale, same time of day — on days 0, 1, 2, 3, 5, 7, 10, 14, 17, 21, 24, 28, 30 grams; g/day per interval Life and consumption pattern
Fragrance intensity Blind room score on days 3, 7, 14, 21, 30 Your written house scale (example 0–5) Whether scent holds across the month
Reed condition Photograph reed tops against a white card on days 0, 14, 30; grade them Example 0–3 reed grade Darkening, stickiness, residue
Room temperature Min/max room thermometer (not a CSI item), read daily °C min / max / at reading Context for every other number
Clarity Liquid against white and black cards on days 0, 7, 14, 30 C clear · H haze · L layers · D droplets · S sediment That the liquid stays single-phase
The CSI principle
A formula passes only when all four lines pass: scent held, life on target, reeds acceptable, liquid clear.
Thirty days of one measurement is a test of that measurement. Thirty days of four is a test of the product.

Setting up: bottles, room and rules

Three bottles per formula is the labelled working practice for a decision test (two is enough for a screen, as elsewhere in this section; a launch decision deserves three). Add one capped bottle filled with either blend and no reeds: it should not lose weight, and weighing it first each session checks both the scale and the caps. All seven bottles from one pack, one room, one shelf height, out of direct sun, away from fans, AC outlets, windows and doorways.

Write the house rules before day 0Your room-score scale, your reed-grade scale, your clarity codes, your pass lines and the target life. Write them at the top of the sheet and never change them mid-test. There is no industry standard for any of them; they are yours.
2
Mix both formulas by weight, rest, checkEach batch is 362.2 g including a 5% filling allowance: 72.5 g of Jasmine and 289.8 g of base. Rest 24–48 hours as both pages ask; check clarity on white and black cards before filling.
3
Record the dry weightsWeigh each empty bottle with cap and each bundle of 6 dry reeds. Fill each bottle to 115 g by weight. Label L1–L3 (Lift), S1–S3 (Softness), K (capped check).
4
Day 0: reeds in, one flip, first readingsInsert reeds, give every bottle the same first flip at the same time, then weigh, photograph reed tops, check clarity, read the thermometer. Decide now whether you will flip again during the test — the honest default is never, or on a fixed weekly day for every bottle — and write it down.
5
Days 1–30: follow the schedule exactlyWeigh on the scheduled days at the same time, reading the thermometer at each session. Score blind on the scoring days: someone else codes and places the bottles, you score each one alone in the test room with fresh-nose breaks. Photograph reeds on the photo days against the same white card.
Score one bottle at a time
Six diffusers in one room score as one smell. Keep the bottles in a neighbouring room and bring each into the test room alone for its reading, after the room has aired. It is slower, but it is the only way a blind score means anything — and noses adapt to a scent they keep breathing, a commonly described effect that makes every bottle after the first seem weaker.
The common mistake: changing something halfway. Week two, one formula seems weak, so its reeds get flipped or a bottle moves to a warmer shelf. From that day the test compares two different conditions, and the month is lost. Fix: no interventions after day 0 unless they are on the written plan and applied to every bottle. If you must change something, start a new 30 days.

Example reed grade — YOURS, not a standard · photograph tops against a white card
Reed condition scale
Grade What you see What it may mean (commonly described)
0 Same as the dry reed apart from wetness Clean delivery
1 Tips slightly darker than the stem Normal build-up at the evaporating end
2 Tips clearly darker; slightly tacky to touch Heavier components or residue collecting
3 Dark, sticky tips; liquid line visible well below the top Delivery likely restricted — see dark, sticky reeds

Then do the arithmetic for each bottle. Interval rate = (earlier weight − later weight) ÷ days between them. Liquid left at any reading = that reading − the bottle's empty weight − the dry reeds − the liquid the reeds hold (estimate it once by weighing a saturated spare bundle at day 2). Projected life = liquid left ÷ the average rate of the last two or three intervals. Here is the arithmetic with invented numbers, chosen only to show it and not a measurement of any CSI base: a bottle that weighed 650.00 g on day 2 and 578.44 g on day 30 lost 71.56 g in 28 days — 2.56 g/day — which from a 115 g fill projects to 45 days.

Reading thirty days of numbers

Look at the shape before the average. A steady rate, a falling rate and a rate that tracks the thermometer mean three different things.

Plot each bottle's interval rate against the day, with the room's mean temperature underneath. Three shapes are common. A roughly steady rate after day 2 means the formula and reeds are delivering consistently; the average is a fair life estimate. A rate that falls steadily through the month while temperature stays level points at the reeds — tips loading up, delivery slowing — and usually shows as a rising reed grade. A rate that rises and falls with the thermometer means the room's weather is driving it; the comparison between formulas is still fair, because both met the same weather, but your life claim needs the season in it.

Intensity has its own shape. A score that is high in week one and drifts down is commonly described for many oils as lighter components leave first; strong for three days, then weak covers the early part of that curve. What matters for the decision is where the score sits from day 14 to day 30, because that is the product your customer lives with. Compare the two formulas on their day-14 to day-30 means, and on the spread between their three bottles — a formula whose three bottles disagree widely is less predictable even if its mean is higher.

Working decision lines · all labelled — set your own before day 0
How each formula passes or fails
Line Example pass rule (yours to set) Lift Softness
Scent held Mean score from day 14 to 30 at or above your pass line; no bottle below it Pass / Fail Pass / Fail
Life on target Projected life at day 30 at or above your target (45 days in this example) Pass / Fail Pass / Fail
Reeds acceptable Reed grade 2 or better at day 30 on all three bottles Pass / Fail Pass / Fail
Liquid clear C at every clarity check Pass / Fail Pass / Fail
Consistent The three bottles' day-30 rates within a spread you accept (example: ±15% of their mean) Pass / Fail Pass / Fail

If both pass, choose on what remains: scent character your panel prefers, cost (identical here) and the reed grade. If one passes and one fails, the choice is made. If both fail on the same line, the base was not the variable that mattered — look at reeds, load or the oil, using the shorter screens in this section: reed count, flip dependence, excessive consumption and clarity. Comparing loads by throw, consumption and cost per day applies the same 30-day thinking to load.

Turning the result into cost per day

At production rates — Jasmine at ₹3.92 per g (1 kg) and either base at ₹2.20 per g (both are ₹1,099.00 per 500 ml; example density 1.00 g/ml) — the 115 g fill costs ₹292.44 in liquid in Lift and ₹292.44 in Softness. With the ₹106.20 120 ml Gold bottle and 6 black reeds at ₹8.00, the bottle is ₹446.64 in materials, before labels, box and labour. Divide by the projected life from your sheet and you have the materials cost per day of use.

Materials ₹446.64 per bottle · the lives are what YOUR 30-day projection gives — this table only divides
Cost per day of use at each projected life
Projected life Average loss that implies Materials per day Liquid per day
30 days 3.83 g/day ₹14.89 ₹9.75
40 days 2.88 g/day ₹11.17 ₹7.31
45 days 2.56 g/day ₹9.93 ₹6.50
60 days 1.92 g/day ₹7.44 ₹4.87

Because both bases cost the same here, the 30-day result decides on performance alone, which is the cleanest comparison you can run. Where two bases differ in price — Longevity is ₹1,296.00 per 500 ml against ₹1,099.00 for the other four — the cost per day of use is the fair way to compare them, because a dearer base that lasts longer can be cheaper per day. Is a more expensive base worth it? runs that comparison.

Thirty days of four measurements is a product decision. Thirty days of one measurement is a guess with a calendar.

Argued against our own interest, plainly. If a fourteen-day screen already showed one formula failing clarity or scent, you do not need a 30-day test to reject it — and you do not need to buy the second base to confirm what you already know. Thirty days is for the formula you intend to sell. Buy for that, not for a broad comparison you will never act on. And no CSI page, ours included, is a substitute for this sheet: we publish no longevity data for any base.

Apply on day 30, from the top. Stop at the first true line.

Working decision rule · one action per line
From thirty days to a purchase, or a retest
If this is true It means Do this
The capped check bottle lost weight Scale or cap problem Buy nothing. Fix it and re-run
Something changed mid-test The month is not a fair comparison Buy nothing. Restart
One formula passes all four lines; the other fails one Clear winner That base in 500 ml production quantity; print the life from the projection
Both pass Either works Choose on panel preference and reed grade; keep the other as a backup
Both fail the same line The base is not the variable Back to the screens: reeds, load, oil

Keep the sheet with the product file, keep one retained bottle of the winning batch sealed, and repeat a shorter check whenever a material changes. The systematic method for a weak diffuser uses this protocol as its final stage, and a reed diffuser quality-control checklist turns its lines into release checks. For the season, winter and summer show how to measure the swing.

Why trust this guide

CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished diffusers. The easy answer for a base seller is to quote a life figure. This page publishes none, because we have none: it gives you the protocol to measure your own, compares two of our bases that cost the same so the test decides on performance alone, and says plainly that we publish no throw, evaporation or longevity data for any base, oil or reed.

Diffuser bases, fibre reeds, Gold bottles and measuring tools are CSI live pricing, pulled 14 October 2026; fragrance oils are CSI live pricing, pulled 24 September 2026, stock re-checked 14 October 2026. Every blend split, ml-to-gram conversion, per-bottle cost, cost per day and kit total on this page is computed and shown to two decimals so you can check it, and every density used is a labelled example with its ±5% sensitivity.

Bottle counts per arm, weighing schedules, rest and hold checkpoints, room-scoring scales and allowances are labelled working practices, not industry standards — none exists for reed-diffuser performance.

Frequently asked questions

How do you test a reed diffuser?
Weigh the bottle with reeds in on a fixed schedule, score the room blind on a written scale, photograph the reed tops, check the liquid against white and black cards, and log room temperature. Compare against a control bottle in the same room.
How long should I test a reed diffuser before selling?
A 14-day screen shows direction; a 30-day test confirms the formula you intend to sell. For a life claim beyond 30 days, project from the last intervals and say it is a projection — or test longer.
How do I measure how fast a reed diffuser evaporates?
Weigh it with reeds in, cap off, at the same time on scheduled days. Grams lost ÷ days between readings is the rate; start from day 2 to skip the reed soak and first-flip burst.
Does room temperature affect reed diffuser tests?
Yes, commonly. Record it daily with a min/max thermometer and keep a control in the same room so both formulas meet the same conditions. Do not apply a correction formula — none is reliable for these bases.
How do I compare two reed diffuser bases?
Same oil, load, reeds, bottle, fill and room; three bottles each; 30 days on the same sheet. CSI's Lift and Softness both cost ₹1,099.00 per 500 ml, which makes the comparison purely about performance.
What do dark reed tips mean?
Commonly, heavier fragrance components or residue collecting where the liquid evaporates. Grade them on a fixed scale at days 0, 14 and 30; a rising grade with a falling rate points at restricted delivery.

Non-price figures and assumptions: Load convention: fragrance load is a share of the total blend by weight (oil g = batch g × L; base g = batch g × (1 − L)). Example formula: 115 ml fill in the 120 ml Gold bottle (labelled example) at an example blend density of 1.00 g/ml (±5% shown) = 115 g; at 20% = 23.0 g oil + 92.0 g base. Working practices: 3 bottles per formula plus one capped check bottle, 5% filling allowance, weighing on days 0, 1, 2, 3, 5, 7, 10, 14, 17, 21, 24, 28, 30, blind scores on days 3, 7, 14, 21, 30, reed photos on days 0, 14, 30, clarity on days 0, 7, 14, 30, daily min/max temperature (thermometer not a CSI item). The day-2 and day-30 weights in the worked arithmetic are invented. Per-bottle costs use Jasmine's 1 kg rate, 500 ml base prices at the example density, ₹106.20 per bottle and ₹8.00 per black reed. What CSI's product pages state (quoted as claims to test, not CSI test results): every reed & car diffuser base page gives a 10–30% fragrance range of the total blend and a 24–48 hour rest before bottling; Pure Performance adds "20% recommended", a "typical working blend 75% base + 25% fragrance" and "flip reeds after the first hour"; Longevity says to allow 2–3 hours before the first flip, to keep the bottle away from strong air currents, and that "heavy oils like oud can cloud at maximum load in some bases". The fibre-reed pages state a length of 20.3 cm and that "for a standard 50–100 ml diffuser bottle, 6–8 reeds gives a good balance", with more reeds for stronger throw and faster diffusion and fewer for subtler, longer-lasting results. The Gold bottle's variants are 50 ml and 120 ml (its text also says "50 and 100ml"); neck diameter and fill line are not published. CSI publishes no composition, density, viscosity, evaporation rate, flash point or SDS figure for any diffuser base; no throw, evaporation or longevity data for any base, oil or reed; no reed diameter; and no IFRA percentage for any oil — ask on WhatsApp for the oil's IFRA certificate and read its Category 10A limit (reed diffusers are listed under Category 10A as commonly summarised in suppliers' IFRA guides; confirm on the certificate). The lower of the base page's 30% and the oil's Category 10A limit always wins. CSI sells fibre reeds, not rattan, and does not sell DPG, Augeo, perfumer's alcohol, IPM, reducers or stoppers. Material costs exclude labour, labels, packaging, freight and GST. Diwali 2026 falls on Sunday 8 November.
