For candle makers

Stop guessing. Start testing.

Match a wick to your wax, vessel diameter, and fragrance load — then log burn tests hour by hour until the melt pool is right. Wasted wax is expensive; a wick is not.

What's inside

The step that fails most often, finally made systematic.

01 · Match
Wick from your inputs
Vessel diameter, wax base, and fragrance load give a recommended series and size — adjusted for how each wax burns.
02 · Range
Never one answer
You always get the size up and size down too, because dye, fragrance, and vessel shape all shift the result.
03 · Series
ECO, CD, LX, Hemp
The series you actually stock, with rated melt-pool diameters for every size in the range.
04 · Burn test
Hour-by-hour log
Record melt-pool diameter, flame height, soot, and mushrooming each hour — fast, one-tap entries.
05 · Diagnose
Fix what went wrong
Tunnelling, heavy soot, a flame that's too tall — pick the symptom and get the likely cause and next wick to try.
06 · Compare
Tests side by side
Put two burn tests next to each other and see which wick actually held a full pool.
Read the pool

A full melt pool by hour two, or the wick is wrong.

Every burn test charts the melt pool hour by hour, so you can see at a glance whether a wick reached the edge — or tunnelled and never recovered.

Never leave a test candle unattended.
