Before Lighting:

Before burning, always trim the wick to ¼ inch for a cotton wick and 1/8" - 3/16" for a wood wick.

Keep the wax pool clear of wick trimmings, matches and debris at all times.

Burn candles in a well-ventilated room:

Avoid drafts, vents, or air currents. This will help prevent rapid or uneven burning, sooting, and excessive dripping.

Never burn a candle for longer than three hours and cool for at least two hours before relighting.

When lighting a candle, use long matches or a long-reach lighter. Keep your hair and loose clothing away from the flame.
