When melted, forms ice that always cools. Spreads with regular water.

Light cold particles, which quickly freeze water through a cascading effect.
Freeze powder freezes water through a series of reactions. First, water is turned into freeze water:
Next, freeze water converts nearby water into more freeze water:
Finally, freeze water solidifies into ice with ctype FRZW:
The resulting ice will get colder by itself, until it hits -273.15°C. Freeze powder also turns into such supercooling ice (marked with asterisk below) on contact with usual ice:
