Candle making, made measurable

Make better candles with clearer choices and repeatable tests.

Choose wax, size wicks, calculate fragrance, control temperature and troubleshoot the finished burn with practical guides built for real makers.

Start with the four decisions that control the result

Build the candle in the right order

Keep the first formula simple, change one variable at a time and use the deeper guide only when you reach that decision.

01

Complete workflow

See the full path from materials and temperatures to curing, burn testing and safety.

Open guide 02

Choose the wax

Compare soy, paraffin, beeswax, coconut and blends by format, throw, cost and heat tolerance.

Open guide 03

Choose the wick

Use jar diameter, wax, fragrance load and controlled burn tests instead of guessing.

Open guide 04

Set the fragrance

Calculate fragrance by weight, follow supplier limits and judge the result after a full cure.

The candle lab

Find the exact part of the formula you need to improve

Each route keeps one technical question in focus so you can diagnose the variable instead of changing everything at once.

Wax

Select the right wax family and understand how it changes finish, throw, hardness and heat tolerance.

79 guides

Wicks

Size cotton and wooden wicks, understand series differences and correct common burn problems.

53 guides

Fragrance

Work with load percentages, cure time, oil compatibility and hot-throw testing.

48 guides

Color

Measure liquid dye, chips and blocks consistently and prevent specks, fading or bleeding.

41 guides

Containers

Choose heat-safe jars, measure usable capacity and qualify each vessel through testing.

45 guides

Molds

Choose mold materials, wick shapes correctly and prevent leaks, cracks and release problems.

26 guides

Testing & safety

Run repeatable burn tests, record flame and melt-pool behavior and check container heat.

41 guides

Troubleshooting

Diagnose tunneling, soot, mushrooming, weak throw, wet spots and uneven burns.

49 guides
Maker tools

Do the batch math before you melt the wax

Use the calculators as planning tools, then verify the formula against the wax, fragrance and wick supplier guidance.

A repeatable method beats a lucky batch

Change one variable. Measure it. Record it. Test it.

Good candle making is controlled comparison. Keep the jar, wax, fragrance and process stable while you test the variable that actually needs an answer.

  1. Define the goalContainer type, scent target, appearance and use.
  2. Measure by massRecord wax, fragrance, dye and additives consistently.
  3. Control the processTrack melt, add, pour, room and cure conditions.
  4. Burn testObserve flame, melt pool, soot, heat and scent over full cycles.
