Rekindle

When you light the Kerssand candle again, first make sure that the Kerssand has enough wick. If there is enough wick, light the candle like a normal candle. If you run out of wick, and the flame extinguishes itself - you can throw away the solidified pod, and refill your container with fresh Kerssand and a new wick. Make sure ~5mm of the wick is exposed and leave ~4cm of free space on each side of the wick, including about ~1cm at the bottom. This way, the container of your choice will stay clean and not come into contact with melted candle wax. If you have chosen a shallower container, you can cut the wick in half. You can also add different elements that you like (flowers, stones, etc.) Kerssand can also be used as a floating candle (as long as your wick has at least 1cm of free space at the bottom), the floating candle’s burntime is 2-3hours at a time. The sand can then again be dried out and re-used as soon as it is completely dry. Also feel free to drip any essential oils according to your need in your kerssand around the wick for a nice lasting scent.

If you want to burn more than one fuse and one container
Make sure that the fuses are ~8cm apart and the fuses are at least ~4cm away from the decor elements. Since the burning diameter of one wick is ~8cm! If the wicks are burned too close to each other (closer than ~8cm) the heat of the flame will increase and also make the wax melt faster. In this case, the fuses can sink into the melted wax and extinguish.
