I was on Reddit and saw a post about someone who made custom textures for a blast furnace and smoker (check that out here) and a lot of people in the comments were asking if it can smelt raw ores so I did that.

Put the Smeltable Raw Ores Data in your datapack folder and the Smeltable Raw Ores Resource in your resource packs.

If you don't know how to do so look it up.

I heard somewhere that they changed the recipe for copper blocks to require 4 ingots (like glowstone) but after playing the new update I realized you need 9 ingots so I removed the structure void part. So yeah no need for a resource pack
