Ice acts very similar to Snow in the sense that it melts when it comes into contact with Fire , is near a Torch , or is touched by Lava for a short period of time. Ice is not affected by Fire, but when melted with Lava, it will produce Water. This will also happen if Ice is destroyed and there is a Block beneath it.
Ice does not commonly have a use, and was most likely implemented in Minecraft for show and visual effect. Ice cannot naturally be gathered; however, if a Pickaxe has the Silk Touch Enchantment , Ice can successfully be gathered without destroying it.
Ice can be used to make traps, but is not efficient in this as water makes a better substitute in moving mobs. Melted Ice will disappear in the Nether .
In Mob traps, Ice is great for making faster Mob delivery systems. Water traveling over Ice propels items and Mobs faster, decreasing the amount of time the Player must wait.
