Invalid data value wooden slabs are item forms of the wooden slab block with damage values outside of the usual range which wooden slabs can usually be obtained in.

Without the use of commands, invalid data value wooden slabs are unobtainable in the last versions in which they existed without inheriting them from a prior version in which they were obtainable.

Block transmutation with doors can be used to obtain wooden slabs with metadata 6 to 7, and with arrows can be used to obtain blocks with metadata 6, 7, 14 and 15. These blocks can be mined in 14w21b or earlier^[verify] to obtain wooden slabs with values 6 and 7.

Inventory appearances (values marked in red are not known to be obtainable in survival mode)
