Scenting a room is not just lighting some fragranced candles. Michelle Liu, the head of Escentials, shares her tips for making the scents, and your candles, last.

Firstly, make sure you have enough candles for the scent to come through. Ideally, use a 180g to 220g candle for every 10 sq m (107sqf) of space. A larger living room might require three to four candles to create a consistent smell.

Always burn a candle for at least one hour to allow the candle wax to melt properly and provide sufficient time for the scent to evaporate. If you’re in a rush to go out, opt for a diffuser or room spray as a quick fix instead of a candle.

Observe where the candles are placed. If a window is frequently opened, or if the room is air-conditioned – these are factors that affect the strength of a scent.

Before lighting, trim the candle wick to between 0.5cm and 0.6cm. The wick length will impact the burning quality of the candle. For example, if the wick is too long and over burnt, when lit, it will create heavy smoke and block off proper heat transmission to the surface of the wax. Whenever possible, put out the candle with a candle snuffer or a candle lid, to cut oxygen supply to the flame and minimise the generation of smoke, and prevent a burning smell.

On how to make candle scents last, Jo Malone’s senior retail and education manager, Christopher Don Au, suggests: “After continually smelling the same scent for more than 15 minutes, our olfactory system will become less sensitive, making us think the scent has disappeared. For a longer lasting fragrance, we suggest using different scents in different areas of the home, so our olfactory system can be stimulated as we walk from room to room.
