Replacement wick for catalytic lamp.

The catalytic stone of the lamp usually has a lifespan within 200 - 300 ignitions.
After that, it begins to smolder and its temperature becomes too low to support the catalytic combustion process needed to spread the aroma.
If you notice a similar effect in your lamp, it's time to replace the wick.

After placing a brand new wick in a catalytic lamp filled with liquid, it is advisable to let it soak for about an hour, after which you can turn on the lamp.
