Description
Blast Furnace is crafted from one furnace, five iron ingots, and three smooth stone blocks arranged in the standard pattern. The device complements its food-focused sibling the smoker: it accepts only ores, metal tools, and metal armour, smelting them in five seconds instead of ten — twice the speed of a regular furnace. Players running large iron or copper farms switch to this device almost immediately for the throughput.
A secondary use makes the device essential outside production: feeding old metal tools and armour into it returns one iron or gold nugget per item — useful for recycling damaged loot from dungeons and abandoned mineshafts. Like the smoker, the block serves as the workstation of the armorer villager profession; placing it in an unstaffed village recruits an unemployed villager into the armorer role, unlocking trades for diamond armour at master level. Mining returns the device intact regardless of contents.
