Candle Testing Sheet for Recording Burn Results and Wick Performance

candle testing worksheet

Use a structured burn log to capture flame height, melt pool width, and container temperature at 30-minute intervals during the first four hours of use. Record numeric values rather than impressions to spot trends across batches.

Document wick diameter, trim length in millimeters, and wax blend ratio before ignition. Pair these inputs with measured outcomes such as soot marks, tunnel depth, and fuel consumption per hour to support repeatable adjustments.

Reserve space for scent dispersion notes at set distances, for example one and three meters from the source. Mark strength levels on a fixed scale from 1 to 5 after each hour to track changes over time.

Include a remarks field for visible issues like mushrooming, flicker instability, or uneven liquefaction. Short, factual entries help compare multiple pours without relying on memory.

Burn Assessment Log for Structured Flame Evaluation

Apply a fixed observation schedule with checkpoints at 15, 30, 60, and 120 minutes to capture flame height in millimeters, liquid wax diameter, and container warmth in degrees. Consistent timing allows clear comparison across pours.

Allocate separate rows for wick size, trim length, and fuel blend ratio before ignition. Pair these inputs with measured outputs such as hourly mass loss in grams and visible residue on the vessel wall.

Use numeric scales rather than descriptive labels for soot presence, flicker stability, and aroma reach. A 1–5 scale reduces subjective drift during repeated burn sessions.

Reserve a comments column for anomalies like off-center melt pools or carbon buildup. Short, factual notes tied to timestamps support later adjustments without relying on recall.

Logging Burn Duration and Flame Patterns During Repeated Trials

Record ignition and extinguish times in minutes using a single timing device to maintain uniformity across sessions. Note total runtime per cycle and cumulative runtime after each relight.

Track flame height at regular intervals, such as every 20 minutes, measured from wick tip to peak in millimeters. Sudden increases often signal fuel oversupply or wick imbalance.

Document movement traits like lean, flicker rate, and split tips with short numeric codes rather than descriptive phrases. This method keeps entries concise and comparable.

Include ambient conditions such as room temperature and airflow direction since minor drafts can alter burn rate. Pair these readings with each trial entry to explain variations.

Tracking Wax Pool Depth and Surface Changes During Use

Measure melted material depth with a metal ruler after 60 minutes of use, recording values in millimeters from container wall to center. Consistent depth across the diameter signals balanced heat spread.

Log surface appearance using short markers such as clear, cloudy, ripples, or cracks. These indicators help link formulation traits to visual outcomes.

Note edge behavior by checking whether solid residue clings to the vessel after two hours. Remaining buildup wider than 5 mm suggests insufficient melt reach.

Record cooling results after full solidification, focusing on sinkholes, frosting, or uneven texture. Pair these notes with prior depth readings to trace cause and result.

Use a simple table layout to compare multiple runs side by side, keeping time marks and measurements aligned for clear pattern recognition.

Comparing Wick Sizes and Trim Length Outcomes

Use identical containers and fuel blends while varying only the filament gauge and cut height. Trim each strand to a measured length before ignition to isolate performance differences.

Record visible and measurable results after a fixed burn window, such as two hours. Focus on flame height, smoke presence, and container temperature near the rim.

  • Filament diameter and manufacturer code
  • Cut length in millimeters before lighting
  • Average flame height measured with a ruler
  • Soot marks on vessel walls
  • Stability of the light source during use

Compare outcomes by aligning data from small, medium, and large strands in parallel rows. Shorter cuts often lower flame height but may reduce pool reach.

Repeat the process after each trim cycle, adjusting length by 2–3 mm, to map how gradual changes influence burn quality across multiple sessions.

Documenting Scent Throw Strength and Consistency Over Hours

Place the lit product in a closed room of known size, such as 10–12 square meters, and keep doors and windows shut during the session.

Log aroma intensity at fixed intervals, such as every 30 minutes, using a simple numeric scale from 0 to 5, where 0 indicates no detectable fragrance and 5 indicates full room coverage.

Note how quickly the fragrance becomes noticeable after ignition and how evenly it spreads across the space. Record whether the aroma stays stable, fades, or sharpens over time.

Repeat the same process across multiple sessions using identical room conditions to compare consistency. Differences of more than one point on the scale between sessions suggest formula or wick-related variation.

Add brief descriptors such as “soft,” “sharp,” or “muted” alongside numeric scores to capture qualitative shifts that numbers alone may miss.
