Expected Behavior

Expected variant ores (e.g. Deepslate, Red Granite, Diorite versions of Stone ores) to process as shown in Ore Processing Diagram.

Actual Behavior

Variant ores cannot be processed in Macerators or Furnace, and these expected recipes do not appear in JEI/EMI.

Steps to Reproduce

1. Create a new world.
2. Put Granite Magnetite Ore in a powered HV Macerator
3. Nothing happens.
4. Put Magnetite Ore in the same macerator
5. Maceration begins

Additional Information

#1848 (and by extension, #1353 and #1839) is the same issue from the user perspective, but they have since been (presumably) fixed in #1910.
This bug has now resurfaced several releases later in 1.4.6, and is also applicable to the GCyR ores.

Update: It turns out the issue results from the config allUniqueStoneTypes: false, which is intended behavior.

Instead, the real issue lies in the fact that, while hidden in JEI, the variant stone types are obtainable through the creative menu.
