In my opinion, coal should spawn in flat layers of coal blocks (or perhaps retexture coal ore to something more realistic looking, and require grinding down to get a few coal items, like rock salt). Coal in real life occurs in coal seams, not random veins of coal ore.

Overall I really like the idea. I don’t know if it’s something we will ever see implemented, but it would certainly make mining a lot more fun!

Slate is probably the closest to Sarlluin. Although Blue Sandstone isn't rare either.

As Slate is Metamorphic rock made up of compressed Shale, Clay, and Volcanic Ash, maybe we could craft Slate using Shale, a clay ball and an obsidian shard (closest thing to Volcanic ash in the mod as far as I know) or something?
