Snow Block

Snow is a full-sized block version of the snow cover. It is crafted from 4 snowballs, allowing the player to create it through their inventory crafting window. One may not reverse the crafting process, but the block may be placed and destroyed with a shovel, yielding 4 snowballs. If the block is destroyed by hand, nothing is dropped. This makes snow Ideal for playing Spleef, as it can never be collected and re-placed.

Snow blocks are not destroyed by forces that would realistically melt snow or which do melt snow cover, such as lava, fire, and torches, and are unaffected by water. However, they are easily destroyed by explosions.

Snow blocks have many applications, such as building, decoration, and storing snowballs. They blend in well with the taiga and the tundra (ice plains) biomes, and can be used to build snow-themed buildings, such as igloos or snow castles. Snow may still fall on them, making them look bigger than they really are. They are also sometimes used for playing Spleef. One of the most popular uses is for the production of Snow Golems.

As a crafting ingredient
Snow is also used to make Snow Golems by putting 2 snow blocks vertically and a pumpkin on the top as the head (this is done by stacking the blocks in the world, not in the crafting grid). Note that the pumpkin has to be placed last for this to work.

Trivia

 * When a snow block is on grass, before it turns the grass into dirt— the grass block changes as if a snow layer was previously on it.
