exposed/weathered/oxidized

This datapack adds a straightforward mechanic: smelting or blasting any copper block advances its oxidation stage by one level. 

Supported blocks include:
- Block of Copper
- Cut Copper
- Cut Copper Slab
- Cut Copper Stairs
- Chiseled Copper
- Copper Grate
- Copper Bulb
- Copper Door
- Copper Trapdoor
- Copper Chain
- Copper Bars
- Copper Lantern
- Copper Chest

How it works:
Place any of the copper blocks listed above into a furnace or blast furnace. After smelting, you'll get the next stage of oxidation for that block.

Oxidation stages progression:
Block of Copper → Exposed Copper → Weathered Copper → Oxidized Copper

Note: 
- Waxed copper blocks cannot be smelted (they are locked and do not oxidize further).
- 2 ticks for one block while smelting/blasting
- Standard fuel is required.
- This datapack does not modify any vanilla recipes or mechanics — only adds smelting recipes for oxidation progression.

Supported Minecraft version: 1.21.1

Compatibility: Works with any other datapack or mod that does not override the same smelting recipes.

Installation: Place the datapack in your world's datapacks folder. No configuration needed.
