Lumite Slabs are crafting materials that can be made in a Processor. Like with everything else crafted in the Processor no recipes have to be unlocked for this. 2 Lumite Slabs can be processed from 1 Lumite(Bar) that is made from Lumite Ore in a Forge. Lumite Slabs can then further be processed into 4 Lumite Rods each if needed. Lumite Slabs are used for different crafting recipes, like for Lumite furniture and a number of Lumite building blocks too (as of R26 in December 2015)..
