The Block of Coal (also known as Coal Block) is a compact way to store coal, and can be used for decoration and fuel.

As a fuel source, it can smelt 80 items, whereas every coal used one-by-one would only result in 72 items smelted. The block of coal itself is flammable, and burns in much the same manner as wood.

Crafting

Blocks of coal can only be crafted with regular coal, not charcoal. It is crafted in the same way as other mineral blocks.

Usage

As a fuel

Blocks of coal can be used as fuel in a furnace. One block of coal smelts 80 items, which is more than the smelting time of the 9 coal items used to craft it. Note that since only 64 items can fit in the furnace at a time, to prevent wasting fuel you should restock the smelting items before they run out, and empty the output slot before it fills up. Hoppers come in handy for automating this, but be warned: using a hopper to unload a furnace forfeits any experience from the smelting.

A '''knowledge book''' is a utility item that reveals available [[crafting]] recipes to the player when {{control|used|use}}.

== Obtaining ==
Knowledge books can be obtained only by using [[commands]], as it is not found in the [[creative]] inventory; therefore, it is impossible to obtain in other modes such as [[survival]] and [[adventure]] except with commands.

For example, to give oneself a knowledge book that reveals the recipes for [[bucket]]s and [[flower pot]]s, use: {{cmd|give @s minecraft:knowledge_book{Recipes:["minecraft:bucket", "minecraft:flower_pot"]} }}.

== Usage ==
Knowledge books are used to reveal recipes to the player who uses it, by adding it to their [[recipe book]]. Using a knowledge book consumes it, removing it from the player's inventory.

Knowledge books are especially useful to mapmakers in conjunction with {{cmd|gamerule doLimitedCrafting true}}, because then any item is craftable only if its recipe is unlocked first.
