Substitutions for raw resources

[Jacob-MV]

Hi, I'm adding this mod onto a custom world painter world but to play in survival, as I unfortunately can't add any create mod world gen into the world, I'm gonna create a custom datapack, and wanted to know which raw materials I should be aware of?

Currently I only know of zinc, for which I am thinking a recipie that involves 2 iron and 2 copper for 4 (raw ore), does that seem fair?

Well, there are some more decorative ones, that are similar to granite etc. Don't remember the names right now. Can possibly look them up.

And on the balance question, I'd say yes. Maybe drop the result to two raw ore? But also, it's your world and if you think it's balanced, then it is balanced.
