First burn

Let the melted wax reach the edge of the jar before you blow it out, usually 2–3 hours. This sets the "memory" of the candle and stops tunnelling.

Every burn

Trim the wick to 1/4" and burn for no more than 4 hours at a time.

Safety

Never leave a burning candle unattended. Keep it on a heat-safe surface, away from drafts, pets and children. Stop burning when 1/2" of wax remains.
