Ice

Ice is a semi transparent solid block formed on snow worlds from exposed water, it was added in Version 1.0.4 alongside snow, and is slightly slippery. Any block of water exposed to snow will eventually freeze into ice. All sides of an ice block use the same texture.

Properties
Ice can be easily destroyed without tools, except while underwater, and in this case a pickaxe greatly helps. Providing there is another block directly underneath the ice it will revert back to water when broken, otherwise it will shatter into nothing in much the same way as glass. Ice can also be melted with the use of any block that gives off heat such as torches, furnaces and lava, and will be prevented from forming be the same. However torches cannot be placed on ice directly.
