Nether ice should be an ice found in the nether that looks a bit like like lava but doesnt change color it should be exetremely fragile (2 or 3 seconds to break with your hand). Once it is destroyed it turns into lava if you right click nether ice with a water bucket it will turn into obsidian and the water will disappear (this can also happen in the nether since the water disappears anyways).The only way to collect nether ice is to use the inchantment silk touch.
i don't think so.
oh well good thought :smile.gif:, but that would be rather dangerous, and it doesn't melt does it?
