Trivia

 * Furnaces function as multiple real-world devices combined into one block: bloomeries and blast furnaces (for smelting ores), ovens (for baking and cooking), charcoal pits (for the charring of wood) and kilns (for baking of clay).
 * Tamed cats often sit on top of lit furnaces.
 * A lava bucket is the most effective fuel to use, smelting 100 items, although a block of coal is the best renewable fuel, smelting 80 items.
 * The Lit Furnace block was legitimately obtainable in bedrock addition by mining a furnace that is smelting an item while the pickaxe has silk touch. When highlighted in the inventory its name was 'lit_furnace'.
