Ore Plated Cobblestone
To allow for building of the tackiest and gaudiest of things for low cost, an "Ore Plated Cobblestone" system has been introduced with Season 5.
When crafting a normal Ore block, such as an Iron block, Raw Gold block, or Diamond block, you will receive a non-placeable version of that item instead. This item can still be turned back into the original non-block material by putting it through a crafting table. In effect, these items have been repurposed into being an inventory consolidation item.
Ore Plated Cobblestone blocks are made when crafting together a Cobblestone or Cobbled Deepslate block with 1 item of the supported ores. A "Plated Cobblestone" version of that bulk ore block will be created
