With Oil:
As the water burns it will slowly evaporate. The water will eventually change colour and once there is little to none water left, you MUST blow out your tealight candle.
If you allow the Nur to burn it can lead to the glass burning as there will be no scent water left.
*Approximate Burn Time of Nurs:
Flower = 7 Hours
Pink and Violet Blossom = 2 Hours
Golden Hour = 3 Hours
Matte Collection = 8 Hours
Modern Black = 1 Hour
Animal Collection = 1 Hour
Sapphire Ripple = 1 Hour
Snow White and Smokey White = 6 Hours
*Burn time refers to the time it takes for the water to evaporate when the Nur is in use. The following has been tested with small tealight candles.
You should use your Nur with a small tealight as shown in the How it Works video.
With Nur Crystals:
Once the aroma is released from the crystals they will turn pale white. Once you feel no more aroma is being released you can blow out your tea light candle. The crystals do not melt they will remain the same.
