Blue Ice

Blue ice is a solid block similar to packed ice.

Natural generation
Blue ice naturally generates on the bottom of the icebergs in frozen ocean biomes.

Blue ice generates in some snowy tundra village houses.

Obtaining
Blue ice can be obtained using any tool enchanted with Silk Touch or by crafting it with 9 packed ice blocks. Breaking the block without Silk Touch drops nothing.

Trading
Wandering traders have $1/6$ chance to sell blue ice for 6 emeralds.

Usage
Blue ice is slippery, causing most entities to slide, including items. It is even more slippery than ice or packed ice. This also allows for increased speed of items in water currents by placing the blue ice under the water current. Mobs do not travel faster in water currents on blue ice.

Blue ice is a completely solid block and allows the placement of any objects on top.

Unlike normal ice, blue ice does not melt when placed near light sources.

Boats travel faster on blue ice than on either normal ice or packed ice, being able to reach a top speed of 60.606 m/s (as opposed to 39.7 m/s on packed ice).

$$, blue ice is capable of giving off a light level of 4.
