Scented candles.

Let the wax melt all the way to the edge of the glass the first time, about two hours. Every burn after follows that first one.

Trim the wick to 5 mm before each lighting, for a calm, even flame without soot.

Burn for no longer than four hours at a time, then let the candle cool completely before lighting it again.

Never leave a burning candle unattended. Keep it away from children, pets, draughts and anything flammable, on a heat-resistant surface.

Stop when about 1 cm of wax remains. Once cool, wash the glass out. It is a real serving glass, ready for the table again.
