Variant Furnaces

One furnace can do the work of many.

Variant Furnaces replaces sprawling furnace arrays with iron, diamond, and netherite furnaces that deliver increasingly higher throughput.

Furnace	Throughput
Vanilla	1×
Iron	2×
Diamond	4×
Netherite	8×

Familiar furnace behavior

Every variant uses the standard furnace interface and fits into existing setups without extra configuration.

Crafting follows Minecraft's equipment progression: vanilla to iron, iron to diamond, and diamond to netherite.
