Item durability is a property to which certain crafted items, including all tools, weapons and armor, as well as certain other usable items, are subject. It represents the number of useful actions an item can perform and depletes upon item use. For tools and weapons, item durability represents the number of available uses before the tool is destroyed. For armor, it represents the amount of damage that can be absorbed before the armor is destroyed.
The remaining durability of any item can be seen by looking at the item's durability bar on the bottom of the item icon in the inventory and action bar. An item that has not once been used will not display a durability bar. As the item's durability decreases, the bar's colored area shortens right to left, changing color from green to red and leaving an empty grey part. When the item has only small number of uses left, the durability bar is represented as empty, due to rounding to the nearest pixel 1-down.
The numeric durability of your items can be displayed in game by pressing F3+H, or for PE players, downloading an app called Minecraft Toolbox shows this automatically as soon as you equip it. (This enables various additional information in the tooltips for items in the player's inventory.) Note that the durability value displayed there is one less than the actual durability of the item: after the value hits 0, the item can be used one last time.
Only players can reduce the durability of items. Weapons or tools picked up by mobs that are used against a player will not lower in durability; it will remain the same as when the weapon or tool was first picked up by the mob.
Armor durability
Armor durability is based on the armor's type (head, torso, legs, feet) and material (leather, gold, chain mail, iron, diamond). Any time you take damage, each piece of armor you are wearing loses one point of durability.
Armor durability only decreases when its wearer takes damage that the armor is capable of reducing. This includes:
- Direct attacks from mobs and other players
- Getting hit with an arrow, snowball or fireball (either Ghast or Blaze)
- Touching a block of fire, lava, magma block, or cactus
- Explosions (deals more than one point of durability)
- The Thorns enchantment
The following types of damage are not reduced by ordinary armor and have no effect on the armor's durability. Some enchantments can protect against them, but they still don't damage the armor.
- Ongoing damage from being on fire
- Suffocating inside a block
- Drowning in water
- Starvation
- Fall damage
- Falling into the Void
- Poisoning e.g. from a Cave Spider bite or a Potion of Poison
- Instant harm from a Potion of Harming
Values represent the number of points of durability damage this armor must take before it is destroyed.
Note that every time the player takes damage that armor is capable of reducing (see above), it counts as one point of durability damage for every worn armor piece. Armor with the Thorns enchantment automatically loses another point of durability, and two more (for a total of four) if it reflects damage to the attacker.
| Leather | Gold | Chainmail | Iron | Diamond | |
|---|---|---|---|---|---|
| Helmet | 56 | 78 | 166 | 166 | 364 |
| Chestplate | 81 | 113 | 241 | 241 | 529 |
| Leggings | 76 | 106 | 226 | 226 | 496 |
| Boots | 66 | 92 | 196 | 196 | 430 |
Tool durability
Some tools are not block-breaking tools: This includes hoes, bows, fishing rods, carrots on sticks, and flint and steel. Such tools are no better than bare fists at breaking blocks, as they damage from doing so, but using them for their assigned task will fare you better—they take less damage by being used in their own various manners.
For block-breaking tools, a use is counted only if a player completely breaks apart one block or hits a mob. If a block is partially broken this is not counted as a full use.
Items with an Unbreaking Enchantment do not always lose durability when used; for a given enchantment level, the chance that they will use durability is 1 in (1+level). The result is that they will last an extra level times their original durability, give or take a few.
Note that certain uses cause either no damage or extra damage to the tool:
- Axes, pickaxes, and shovels:
- Breaking a block that breaks instantly counts as 0 uses.
- Breaking other blocks counts as 1 use.
- Tilling a grass block using a shovel to make grass path counts as 1 use.
- Hitting a mob (hostile, neutral or farm animal) counts as 2 uses.
- Hoes:
- Tilling dirt or grass counts as 1 use.
- Hitting a mob counts as 1 use.
- Breaking a block counts as 0 uses.
- Shears:
- Shearing a sheep counts as 1 use.
- Breaking cobweb, leaves, tall grass, tripwire, wool and vines counts as 1 use.
- Breaking other blocks or hitting a mob count as 0 uses.
- Swords:
- Breaking a block that breaks instantly counts as 0 uses.
- Breaking other blocks counts as 2 uses.
- Hitting a mob counts as 1 use.
- Fishing Rods:
- Breaking a block or hitting a mob count as 0 uses.
- Casting the line and reeling it in empty, counts as 0 uses.
- Reeling in an item counts as 1 use.
- Catching the bobber/hook on a block, then reeling it in, counts as 2 uses.
- Using the line to yank on a item counts as 3 uses.
- Using the line to yank on a mob counts as 5 uses.
- Carrot on a Stick
- Flint and steel
- Breaking a block or hitting a mob count as 0 uses.
- Using it to light a Nether portal counts as 1 use.
- Using it to set blocks on fire counts as 1 use.
- Bow
- Firing an arrow counts as 1 use.
- Elytra
- Flying for one second counts as 1 use.
- All other tools can be used indefinitely.
Proper use of tools will maximize their durabilities. Assuming a player uses a tool appropriately, the following list shows the maximum durabilities for tools of each material type.
- Gold - 33 uses
- Wood - 60 uses
- Stone - 132 uses
- Iron - 251 uses
- Diamond - 1562 uses
- Fishing rods - 65 uses
- Flint and steel - 65 uses
- Carrot on a stick - 26 uses
- Shears - 238 uses
- Bow - 385 uses
- Elytra - 432 uses
Video
- Note: The video states that "attacking with a pick, axe or shovel counts as one use". This is incorrect - using a pickaxe, axe or shovel on the wrong type of block only counts as one use, but attacking mobs counts as two.

Tags and Bits are items exclusive to the [[Java Edition 23w13a or b|23w13a_or_b]] [[Easter eggs#April Fools|April Fools' joke]] snapshot from 2023. They are used to craft in-game representations of [[NBT format|NBT tags]].
==Obtaining==
A [[stonecutter]] can be used to cut a [[Name Tag|name tag]] into either 16 "Name" or 16 "Tag" items. These can be cut into 16 Bit items each.
{{Stonecutting
|head=1
|showdescription=1
|Name Tag
|Name, 16; Tag, 16
|description=The resulting "Name" items must be named in an [[anvil]].
}}
{{Stonecutting
|showdescription=
|Name; Tag
|Bit, 16
|foot=1
}}
To be able to proceed from here the <code>nbt_crafting</code> vote must be approved. Bits can be used in a crafting table to craft Left Curly, Right Curly, Left Square, and Right Square. In appears like these are the only tag items that can be crafted from Bits.
A [[Crafting Table|crafting table]] can be used to convert a "Tag" item into a "Byte Tag." The amount of [[stick]]s added to the crafting recipe specifies the value of the Byte, as a [[wikipedia:Signed number representations#Two's complement|signed 8-bit value]]. For example, a "Tag" and a full stack of sticks make a Byte with the value <code>64b</code>, while 255 sticks result in <code>-1b</code>. Only one of the sticks is consumed. Two Bytes can be crafted into a "Short Tag" (equivalent to 16 bit), two Shorts into an "Int Tag" (equivalent to 32 bit), and two Ints into a "Long Tag" (equivalent to 64 bit). Many other combinations that form either 16, 32, or 64 bit are possible. For example, two Shorts and an Int make a Long. When combining values, their digits are stuck together in the given order, e.g. <code>1b</code> and <code>0b</code> make <code>256s</code> (equivalent to 0100<sub>16</sub> in [[wikipedia:Hexadecimal|hexadecimal]]). Undoing any of these crafting actions in e.g. a stonecutter is not possible.
"Float" and "Double Tags" can be crafted by adding one or two [[boat]]s to any numeric tag. A "String Tag" is crafted with a "Tag" and a piece of [[string]].

"Name" and "String Tags" must be named in an [[anvil]] before they can be used. Unnamed Names and Strings always produce a "Sssyntax Error". None of the other tag items can be named.
All these items can be combined in a crafting table to form a short sequence of JSON code, as long as the resulting syntax is valid. For example:
*A pair of Curlies that enclose a named "Name" item and some value, e.g. a Byte, create a "Compound Tag" with the content <code>{Example:0b}</code>.
**Because of the limited size of the crafting table only 3 name-value pairs can be put between Curlies at a time. Compound Tags of any length can be created by concatenating two or more Compound Tags.
**An empty pair of Curlies produces an empty Compound Tag with the content <code>{}</code>.
*A pair of Square brackets that enclose any number of values, e.g. 7 Bytes, create a "List Tag" with the content <code>[0b,0b,0b,0b,0b,0b,0b]</code>.
**Because of the limited size of the crafting table only 7 values can be put between Square brackets at a time. List Tags of any length can be created by concatenating two or more List Tags.
**An empty pair of Square brackets produces an empty List with the content <code>[]</code>.
**"Name" items cannot be used in a List.
The resulting Compound and List Tags can be used as values in other Compound and List Tags, as deeply nested as you want.
==Usage==
Tags appear to have no further functionality. They cannot be eaten or placed in the world, except in an item frame, as each other item can. However, Compound Tags with values like <code>{Enchantments:[{id:"minecraft:sharpness",lvl:127b}]}</code> will show the [[Enchanting|enchantment]] glint and actually act accordingly when used.<ref>https://www.reddit.com/r/Minecraft/comments/129xdyl/i_figure_out_how_the_nbtcrafting_in_the_vote/</ref> This appears to work with many weapon and tool [[Enchanting#Summary of enchantments by item|enchantments]].
In theory, an extremely lucky <code>replace_recipe_output</code> vote can change the crafting recipe for compound tags to output something else. When cheats are enabled you can test this with a command like <code>/vote rule minecraft:replace_recipe_output approve {key:"minecraft:compound_tag",value:"minecraft:netherite_sword"}</code>. However, as long as this vote is approved no other compound tag can be crafted. Use <code>/vote rule minecraft:replace_recipe_output repeal *</code> to undo all recipe replacements.
In combination with the <code>midas_touch</code> vote tag items can be converted into [[Gold Ingot|gold ingots]]. These retain their NBT data. When the world is loaded in another version of the game tag items disappear, but gold ingots persist.
==Trivia==
*This implies that a [[Name Tag|name tag]] is 128 bit.
*Compound and list tags are special in so far that the value they show in their [[tooltip]] is not merely a property of the item, but their ''actual'' [[NBT format|NBT data]]. This is also the reason why naming them is disabled as that would mess up the NBT data.
*The snapshot also contains an [[History of textures/Unused textures|unused texture]] for an {{ItemLink|End Tag}}.

'''Glowstone dust''' is an [[item]] obtained from mining [[glowstone]], and is mainly used to create [[potion]]s with increased strength and decreased duration.
== Obtaining ==
=== Mining ===
When broken using anything other than a [[Silk Touch]]-enchanted [[tool]], a [[glowstone]] block drops 2-4 glowstone dust. A [[Fortune]] enchantment increases the chances of higher drops, with Fortune III allowing an average yield of 3.5 glowstone dust per block.
=== Mob loot ===
[[Witch]]es have a chance of dropping 0–6 glowstone dust upon death. This is increased by 3 per level of [[Looting]], for a maximum of 0-15 glowstone dust. <!-- Do not add the blaze as it is in violation of MCW:UPTODATE due to the Legacy Console Edition being discontinued. Any edit that adds the blaze to this section will be immediately reverted. -->
=== Trading ===
{{IN|bedrock}}, journeyman-level cleric [[villager]]s sell one glowstone dust for 4 [[emerald]]s as part of their trades.

A '''redstone comparator''' is a [[block]] that can produce an [[Redstone Dust|output signal]] from its front by reading [[chest]]s, [[lectern]]s, [[beehive]]s and similar blocks, or repeat a signal without changing its strength. It can also be set to either stop outputting a signal when its side input recieves a stronger one (front torch off), or subtract its side input's signal strength from its output (front torch on).
== Obtaining ==
=== Natural generation ===
Redstone comparators generate in [[Ancient City|ancient cities]].
=== Breaking ===
A redstone comparator can be broken instantly with any [[tool]], or by hand, and drops itself as an item.
{{Breaking row|Redstone Comparator|horizontal=y}}
A redstone comparator is removed and dropped as an item if:
* its attachment block is moved, removed, or destroyed;
* [[water]] flows into its space;{{only|java}}
* a [[piston]] tries to push it or moves a block into its space.
If [[lava]] flows into a redstone comparator's space, the redstone comparator is destroyed without dropping as an item.

}}
== Usage ==
A redstone comparator can be placed on the top of any [[opaque]] block with a solid full-height top surface (including upside-down [[slab]]s and upside-down [[stairs]]). {{IN|be}}, a comparator can also be placed on [[wall]]s and fences. For more information about placement on transparent blocks, see [[Opacity/Placement]].
The redstone comparator has a front and a back — the arrow on the top of the comparator points to the front. When placed, the comparator faces away from the player. The comparator has two miniature redstone torches at the back and one at the front. The back torches turn on when the comparator's output is greater than zero (the arrow on top also turns red). The front torch has two states that can be toggled by {{control|using}} the comparator:
* Down and unpowered (indicating the comparator is in "comparison mode")
* Up and powered (indicating the comparator is in "subtraction mode")
The redstone comparator can take a signal strength input from its rear as well as from both sides. Side inputs are accepted only from [[redstone dust]], [[block of redstone]], [[redstone repeater]]s, other comparators, and [[observer]]s in specific scenarios. The redstone comparator's front is its output.
It takes 1 [[redstone tick]] (2 game ticks, or 0.1 seconds barring lag) for signals to move through a redstone comparator, either from the rear or from the sides. This applies to changing signal strengths as well as simply to turning on and off.
Redstone comparators check their power state before their scheduled ticks update. This results in redstone comparators not usually responding to 1-tick fluctuations of power or signal strength — for example, a [[clock circuit|1-clock]] input is treated as always off from the side, and always on from the rear. This happens because the signal changes back to its original state before the redstone comparator checks its input states. However, certain setups such as powering any input with two separate observer pulses at the same time will cause a redstone comparator to respond to 2 gametick pulses.
The redstone comparator has four functions: maintain signal strength, compare signal strength, subtract signal strength, and measure certain block states (primarily the fullness of containers).
=== Maintain signal strength ===
A redstone comparator with no powered sides outputs the same signal strength as its rear input.
=== Compare signal strength ===
[[File:Comparators Explained.png|Comparators in comparison mode.|thumb]]
A redstone comparator in comparison mode (front torch down and unpowered) compares its rear input to its two side inputs. If either side input is greater than the rear input, the comparator output turns off. If neither side input is greater than the rear input, the comparator outputs the same signal strength as its rear input.
The formula for calculating the output signal strength is as follows:
<code>output = rear × [[Wikipedia:Iverson bracket|[]]'''''left''''' ≤ '''''rear''''' AND '''''right''''' ≤ '''''rear'''''[[Wikipedia:Iverson bracket|<nowiki>]]]</code>
{{-}}
=== Subtract signal strength ===
[[File:Redstone comparator.png|thumb|The greatest of the side inputs A and C is subtracted from the rear input B, outputting 1. If either A or C were greater than B, it would output 0.]]
A redstone comparator in subtraction mode (front torch up and powered) subtracts the signal strength of the higher side input from the signal strength of the rear input.
<code>output = max('''''rear''''' − max('''''left''', '''right'''''), 0)</code>
For example: if the signal strength is 6 at the left input, 7 at the right input and 4 at the rear, the output signal has a strength of ''max(4 − max(6, 7), 0) = max(4−7, 0) = max(−3, 0) = 0''.
If the signal strength is 9 at the rear, 2 at the right input and 5 at the left input, the output signal has a strength of ''max(9 − max(2, 5), 0) = max(9−5, 0) = 4''.
=== Measure block state ===
{{Schematic | caption = A redstone comparator can measure the fullness of a chest, as well as other block states, even through an opaque block.
|rd-ew!|rc-w!|ch|SB|rc-e!|rd-ew!
}}
A redstone comparator treats certain blocks behind it as power sources and outputs a signal strength proportional to the block's state. The comparator may be separated from the measured block by an opaque block. However, {{in|je}}, if the opaque block is powered to signal strength 15, then the comparator outputs 15 no matter the fullness of the container.<ref>{{bug|MC-64394}} (resolved as "Works As Intended")</ref>

A redstone comparator can output a signal indicating how full a container is. (0 for empty, 15 for full, etc.) The table on the right is described more in detail, later in this section.
Containers that can be measured by a comparator include:
* {{BlockLink|Furnace}}
* {{BlockLink|Blast Furnace}}
* {{BlockLink|Smoker}}
* {{BlockLink|Brewing Stand}}
* {{BlockLink|Hopper}}
* {{ItemLink|Minecart with Hopper}} on top of a [[detector rail]]
* {{BlockLink|Dispenser}}
* {{BlockLink|Dropper}}
* {{BlockLink|Chest}}
* {{BlockLink|Trapped Chest}}
* {{ItemLink|Minecart with Chest}} on top of a [[detector rail]]
* {{BlockLink|Barrel}}
* {{SchematicSprite|size=16|ch-e}}{{SchematicSprite|size=16|ch-w}} Large chest
* {{SchematicSprite|size=16|ch-e}}{{SchematicSprite|size=16|ch-w}} Large trapped chest
* {{BlockLink|Shulker Box}} (any color)
Generally speaking, the comparator output signal strength represents the average fullness of the slots, based on how many of that item form a full stack (64, 16, or 1 for non-stackable items).
The ''Minimum Items for Container Signal Strength'' table (right) shows the minimum '''''full-stack-equivalent (FSE)''''' to produce different signal strengths from common containers. A '''''full-stack-equivalent''''' quantifies how many normal 64-stackable items are needed to output a corresponding signal strength. The 's' is a constant 64, with the additional amount needed following after.
One may also consider the terms: '''c''umulative-weight''''' or '''''weighted-sum''''' instead of '''''full-stack-equivalent'''''.
Items that stack to a max of 16 ([[snowball]]s, [[sign]]s, [[ender pearl]]s, etc.), contribute +4 to the ''full-stack-equivalent'' for each unity (count of 1 item). Similarly, items that stack to 1 ([[minecart]], [[boat]], etc.) contribute +64, and items that stack to 64 contribute +1.
Example 1: 3 ender pearls will contribute a 3 x 4 = 12 ''full-stack-equivalent''.
Example 2: 16 ender pearls and 60 redstone dust contributes a 16x4 + 60x1 = 124 ''full-stack-equivalent''.
Example 3: 1 minecart and 60 redstone dust contributes a 1x64 + 60x1 = 124 ''full-stack-equivalent''.
Example 4: To produce a signal strength of 10 from a hopper, one requires a ''full-stack-equivalent'' of at least 3s + 14 = 206 but strictly less than than 3s + 37 = 229. This can be done with 3 minecarts, and 14 dirt.
When a comparator measures a large chest or large trapped chest, it measures the entire large chest (54 slots), not just the half directly behind the comparator. A chest or trapped chest that cannot be opened (either because it has an opaque block, [[ocelot]], or [[cat]] above it) always produces an output of 0 no matter how many items are in the container — shulker boxes can always be measured, even if they cannot open.
;Calculating signal strength from items
:When a container is empty, the output is off.
:When it is not empty, the output signal strength is calculated as follows:
:<code>'''''signal strength''''' = floor(1 + (('''''sum of all slots' fullnesses''''') / ('''''number of slots in container''''')) × 14)</code>
:<code>fullness of a slot = '''''number of items in slot''''' / '''''max stack size for this type of item'''''</code>
:''Example:'' 300 blocks in a dispenser (which has 9 slots), where each block stacks to a maximum of 64 has a 300 ''full-stack-equivalent.'' This produces an output with a signal strength of 8:
<blockquote>
1 + ((300 items / 64 items per slot) / 9 slots) × 14 = 8.292, floored is 8
</blockquote>
;Calculating items from signal strength
:It can be useful in redstone circuits to use containers with comparators to create signals of a specific strength. The number of items required in a container to produce a signal of desired strength is calculated as follows:
:<code>items required = max('''''desired signal strength''''', roundup(('''''total slots in container''''' × 64 / 14) × (desired signal strength − 1)))</code>
:''Example:'' To use a furnace (which has 3 slots) to create a strength 9 signal, players need 110 items:
<blockquote>
max(9, (3×64/14) × (9−1)) = 109.714, rounded up is 110
</blockquote>

==== Miscellaneous ====
[[File:Comparator storage.png|Comparators used to measure containers.|thumb]]
Some non-container blocks can also be measured by a redstone comparator:
;{{BlockLink|Beehive}} and {{BlockLink|Bee nest}}
: A hive or nest outputs a signal strength equal to the amount of honey in the hive/nest.
;{{BlockLink|Cake}}
: A cake outputs a signal strength relative to the amount of cake remaining. Each slice is worth 2 signal strength, with 7 total slices, for an output of 14 for a full cake.
[[File:Cauldron Redstone Strength Values.png|Cauldron signal strength|thumb]]
;{{BlockLink|Cauldron}}
: A cauldron outputs different signal strengths depending on how much water or powdered snow is inside. From completely empty to completely full, the output values are 0, 1, 2, and 3. If lava or powder snow is inside, the strength is always 3.
[[File:Composter Redstone Strength Values.png|Composter signal strength|thumb]]
;{{BlockLink|Composter}}
: A composter outputs different signal strengths depending on the level inside. From completely empty to completely full, the output values are 0, 1, 2, 3, 4, 5, 6, 7 and 8.
;{{Anchor|CommandBlock}}{{BlockLink|Command Block}}
: A command block stores the "success count" of the last command executed, which represents the number of times the most recently used command of this command block succeeded. A "success" is defined by the [[command]]'s success conditions: if a red error message is returned in the chat, the command was not successful.
: Most commands can succeed once per execution, but certain commands (such as those that accept players as arguments) can succeed multiple times, and the comparator outputs the number of times it succeeded (maximum 15 when sent to redstone dust, but in the code it is able to go up to the 32-bit integer limit, and can be used in contraptions with no redstone dust with those values).
: A command block continues to store the success count of the last command executed until it executes its command again, thus the comparator continues to output the same signal strength even after the command block is no longer being activated (it doesn't turn off when the signal to the command block turns off).
;{{BlockLink|End Portal Frame}}
: An end portal frame outputs a full signal of 15 if it contains an [[eye of ender]] and zero otherwise.
[[File:Item frame and comparator.png|A comparator can measure the presence and rotation of an item frame's contents.|thumb]]
;{{EntityLink|Item Frame}}
: A comparator can measure the state of an [[item frame]]'s contents. An item frame comparator outputs 0 if the item frame is empty, or 1 to 8 for any item depending on its rotation: 1 at initial placement, plus 1 for each 45° of rotation for a maximum of 8.
: For an item frame that holds a map, a unit of rotation is 90° instead of 45°, but a comparator still outputs power levels 1 to 8. It takes two full rotations to cycle through all comparator outputs, and each orientation of the map corresponds to two output levels that differ by 4.
: The comparator must be placed behind the block the item frame is attached to, facing away from the item frame. The block must be a full block, and the item frame cannot be submerged in water. Having a sign in the same block as the item frame will prevent the frame from sending a signal as well.{{only|java}}
;{{BlockLink|Jukebox}}
: A jukebox outputs a signal strength indicating which music disc is currently playing. See the ''Minimum Items for Container Signal Strength'' table above.
;{{BlockLink|Lectern}}
: A lectern outputs a signal strength that depends on what page the player is currently on. The calculation used is:
:<code>'''''signal strength''''' = floor(1 + (('''''current page''''' - 1) / ('''''number of pages in book''''' - 1)) × 14)</code>
:This results in page 1 having a signal strength of 1, and the last page having a signal strength of 15. The exception is a single page book, which will output a signal strength of 15.
:For example, a book with 15 pages will output a signal equal to the current page number. A book with 5 pages will output signal strengths of 1, 4, 8, 11 and 15 for the different pages. A book with 100 pages will have the signal strength increase to the next level on pages 1, 9, 16, 23, 30, 37, 44, 51, 58, 65, 72, 79, 86, 93 and 100.
:
;{{BlockLink|Respawn Anchor}}
: A respawn anchor outputs a signal strength of 0, 3, 7, 11, or 15, depending on the "charged" value.
;{{BlockLink|Sculk Sensor}}
: A sculk sensor outputs a signal strength depending on the type of vibration that is detected.
;{{BlockLink|Chiseled Bookshelf}}
: A chisled bookshelf outputs a signal strength between 1 and 6 indicating the last slot interacted with. When no slot has been interacted with yet, it outputs 0.
