Water cooling bowl (sukwoo)
A wide open bowl with a lip, used to cool boiled water before it reaches the leaf. It does one job and does it more repeatably than waiting does: a broad shallow layer of water loses heat quickly and by a similar amount each time, so the same sequence of pours lands in roughly the same place without any measurement.

Porosity
Not porous. It contributes nothing of its own to the liquor, so it can be moved between teas freely and washed with detergent without consequence.
Where it comes from
Korean, and part of everyday green tea brewing as well as of formal darye. Chinese and Japanese practice achieve the same cooling by pouring between vessels rather than with a dedicated one.
Named here rather than presented as generic equipment. The object belongs to a practice, and TeaHQ describes it from the outside.
If you do not own one
A fairness pitcher, a jug, or a second mug. Pouring boiled water into any wide vessel and back again is the whole technique; the dedicated bowl only makes it consistent.
This one is not marked essential. The tea can be made without it.
Brewing methods it is used for
- Korean green tea brewing — A low-temperature approach to Korean green tea in which the water is cooled through a separate open vessel before it ever meets the leaf, and the pot is emptied entirely into the cups each time. Darye names the etiquette; the brewing approach below is shared by everyday practice outside any formal setting.
- Low-temperature brewing (gyokuro style) — A great deal of shaded Japanese leaf in a very small volume of water that is deliberately far below boiling — cool enough that the vessel can be held bare-handed. It is the most extreme low-temperature steeping in common practice, and it exists to extract one part of the leaf while leaving another behind.

Written comparisons
Where TeaHQ has set this piece of teaware against something it is routinely confused with, and argued the differences out in full.
- Water cooling bowl vs fairness pitcher — Two intermediate vessels that sit between the kettle and the cup and do opposite jobs. The Korean sukwoo cools water before it reaches the leaf; the Chinese cha hai equalises tea after it has left the leaf.
