1.7 Block Transmutator
From versions 13w36a-1 to 1.7.5, the arrow variant of the block transmutator can be used to obtain the invalid data values. The machine should be used on a data value 0 using a golden pressure plate set to -15 with that many arrows. This will create the invalid data value which can then be picked up with a pickaxe. In this version, the invalid data value appear as regular  but do not stack with regular  or any other data value variant.
