Frosted Ice

Frosted ice is a translucent solid block.

Obtaining
Frosted ice can be easily destroyed without tools, but never drops. Breaking with silk touch drops nothing, while breaking in any other manner produces water in the same way ice does.

Frost walker
Frosted ice is generated by players walking near water while wearing boots with the Frost Walker enchantment.

Usage
Frosted ice behaves in most ways like ice: it is slightly slippery, causing entities to slide, including items.

Frosted ice naturally melts fairly quickly. The block is created with an age of 0, and is ticked every 1–2 seconds. If a $1/3$ chance succeeds or the block has fewer than 4 frosted ice blocks in the 6 blocks surrounding it, and the light level (including light from the sun) at the block would be greater than 11 minus the age, the age is incremented. When the age reaches 4, the block turns into water and all adjacent blocks have their age incremented (but if these blocks melt also, the effect does not continue to cascade).

When a frosted ice block melts or is broken, any adjacent frosted ice block that has fewer than 2 frosted ice blocks remaining in the 6 blocks surrounding it will immediately melt.
