Blue Ice

Blue Ice is a solid block similar to packed ice.

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.

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

Usage
Blue ice is slippery, causing most entities to slide, including items. 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 placement of any objects on top.

Unlike normal ice and like packed ice, blue ice will not melt if placed near light sources.
