Best is to use a wood that doesn't produce much smoke and smells nice. In Taiwan, serious tea drinkers often choose longyan wood for this purpose. (At least I do.)
The zisha kettle is 17.5 cm high with its handle.
It weighs 450 gr for a volume of 75 cl (80 cl at maximum).
The Nilu is 22 cm high and is very heavy to provide for a stable base.
The whole set (Nilu and kettle) weighs 3.7 kg in its primary packaging.
- Empty and let the kettle dry after usage.
- Don't keep the empty kettle over fire.
- Don't add cold water to a hot and empty kettle. It's best to add the water when there's still water inside or after the kettle could cool down a little.
- Likewise for the Nilu, don't put it in cold water when it's still hot.
