 Any liquid water that touches Nethercap wood will freeze, even if the Nethercap has been harvested and crafted into other forms. Nethercap will not burn and indeed will snuff out fires and even solidify lava it touches. If a Nethercap cavern has a lake its surface will be covered in a solid sheet of ice.
