Calcite now has its own block set in Minecraft Java Edition. According to Mojang’s patch notes for 26.4 Snapshot 7 (released November 3, 2026), Calcite gets Pillar, Slab, Stair and Wall variants, and two new sets sit on top of it: Polished Calcite and Polished Calcite Bricks. By our count of the notes that is 12 new blocks, all of them in a snapshot and not yet in the 26.3 release. Mojang calls Snapshot 7 the “final gameplay features for the upcoming game drop”.

Quick answer: Minecraft calcite blocks in 26.4
- What is new: a Calcite Pillar, Slab, Stair and Wall; a Polished Calcite block with its own Slab, Stair and Wall; and a Polished Calcite Bricks block with Brick Slabs, Stairs and Walls.
- How to craft: Polished Calcite from 2×2 Calcite Blocks, Polished Calcite Bricks from 2×2 Polished Calcite Blocks. The pillar, slab, stair and wall variants can also be made in a Stonecutter.
- Where calcite generates: as the second layer of Amethyst Geodes (since 1.17) and, in 26.4, as one of the two main blocks of the new Ice Caves biome.
- Sulfur cubes: Calcite, Polished Calcite and Polished Calcite Bricks all belong to the Slow Bouncy sulfur cube archetype.
- Status: Java Edition snapshot only. The latest release is still 26.3 and Mojang has not announced a 26.4 release date.

Every new calcite block in Snapshot 7
Mojang’s notes list the three sets one after another. The table below follows the notes’ wording, so the block names are Mojang’s own.
| Set | Blocks in the notes | Crafting according to the notes |
|---|---|---|
| Calcite | Calcite (already in the game), plus new Pillar, Slab, Stair and Wall | Pillar, Slab, Stair and Wall can be crafted using a Stonecutter |
| Polished Calcite | Polished Calcite, Slab, Stair, Wall | Polished Calcite from 2×2 Calcite Blocks; the block, Slabs, Stairs and Walls can also be crafted using a Stonecutter |
| Polished Calcite Bricks | Polished Calcite Bricks, Brick Slabs, Brick Stairs, Brick Walls | Bricks from 2×2 Polished Calcite Blocks; Brick Slabs, Stairs and Walls can also be crafted using a Stonecutter |
What the notes do not say
Be careful with anything beyond the table. The notes do not give the number of blocks a 2×2 recipe produces, do not say which block goes into the Stonecutter for each recipe, and do not list crafting-table recipes for the slabs, stairs, walls or the pillar. They also do not state a mining speed, a blast resistance or a tool requirement for the new blocks. Open the Stonecutter or the recipe book in a Snapshot 7 world to confirm inputs and yields before you plan a big build.
The resource pack changes in the same notes confirm the block names. Mojang added the textures calcite_pillar_side, calcite_pillar_top, polished_calcite, polished_calcite_bricks and polished_calcite_slab_side. The snapshot moves the data pack version to 126.0 and the resource pack version to 102.0, which matters if you maintain a pack (see our Minecraft texture packs list for what we covered on 26.3).
Where to find calcite in Minecraft
Mojang’s notes name two natural sources. The notes do not mention any other place, so treat anything else you read about calcite generation as unconfirmed.
| Source | What Mojang’s notes say | Version |
|---|---|---|
| Amethyst Geodes | Geodes can be found anywhere underground in the Overworld. The outer layer is Smooth Basalt, the second layer is Calcite, the inner layers are Amethyst blocks | 1.17 (June 2021) |
| Ice Caves | A new cave biome that can generate under the colder biomes in the Overworld and “consists mainly of Packed Ice and Calcite”. Ore patches there can replace Ice and Calcite | 26.4 Snapshot 3 (October 6, 2026) |
In practice that means a geode hunt works in any Overworld world, while Ice Caves need a 26.4 snapshot world and a cold area. Our 26.4 Snapshots 1-6 recap covers the rest of the Ice Caves package: icicles, ice crystals, the Frostbite mob and the Freezing effect. If you want calcite blocks in bulk, geodes are the source the notes confirm for release versions, since Ice Caves exist only in the snapshots so far.
The same notes tease “a new decorative block to the game… somewhere” without naming it, so do not assume it is a calcite block.

Calcite and sulfur cubes
The one gameplay rule attached to the new set is a sulfur cube rule. Mojang’s notes say Calcite, Polished Calcite and Polished Calcite Bricks belong to the Slow Bouncy archetype. In the 26.2 release notes that archetype is described as slow speed, high bounciness, medium friction and medium air drag, and it is the one used when a cube absorbs stone-like blocks. The notes do not list it as buoyant. Our sulfur cube guide has the full table of all 13 archetypes, how to absorb a block and how to get it back with Shears.
So a cube carrying a calcite block hits slowly but bounces a lot, which is the opposite of a wood-fed Bouncy cube (fast and high bounce). That is our reading of the stats, not a Mojang recommendation.
Build ideas for the calcite set
Mojang does not publish colors or build advice, and we have not played the snapshot, so this section is our own suggestion from the block list rather than tested play. Calcite is the pale layer seen inside geodes since 1.17.
- Pillars: the new Calcite Pillar has separate side and top textures in the resource pack, which points to a column block you can stack for porches, gates and bridges.
- Stairs and slabs in three finishes: raw, polished and brick versions give three surface looks in one palette, useful for floors, steps and roof edges.
- Walls: every set has a wall, so fences, balcony rails and garden borders can match the main building.
- Ice cave builds: since Ice Caves are made mainly of Packed Ice and Calcite, a calcite-and-ice base can blend into one.

Is calcite in the release yet?
No. As of the check above, the latest release is 26.3 (September 15, 2026) and the latest snapshot is 26.4 Snapshot 7. The calcite block set exists only in snapshots, and you can try snapshots from the Installations tab of the Minecraft Launcher by enabling snapshot versions (general launcher advice, not from the notes). Mojang has published 26.4 snapshots on Tuesdays since September 22, so another snapshot could arrive on November 10, but that is a pattern, not an announcement. Snapshots are test builds, so play them on a copy of your world (our advice, not from the notes).
What else is in Snapshot 7
- A new music disc, “Flurry” by Hyper Potions, with a chance of being found in Igloo basement chests and a comparator output of 7 in a Jukebox.
- Strays now spawn in Deep Frozen Ocean, Frozen Ocean, Frozen Peaks, Frozen River, Jagged Peaks and Snowy Slopes; wearing leather armor stops Zombies and Skeletons converting into Frostbites or Strays.
- Keyboard navigation and narration in gameplay screens, including the Stonecutter, which is where you will craft most calcite variants.
- The “Default” Graphics API setting now randomly picks OpenGL or Vulkan on each startup, as a temporary test.
FAQ
What does calcite do in Minecraft?
In Mojang’s notes, calcite is a building block: it forms the second layer of amethyst geodes and is a main block of the Ice Caves, and 26.4 Snapshot 7 adds pillar, slab, stair and wall variants plus polished and brick sets. The notes list no other use besides its sulfur cube archetype.
How do you make polished calcite?
According to the Snapshot 7 notes, craft Polished Calcite from 2×2 Calcite Blocks. Polished Calcite can also be made in a Stonecutter. The notes do not state how many blocks you receive.
How do you make polished calcite bricks?
Craft Polished Calcite Bricks from 2×2 Polished Calcite Blocks. Brick Slabs, Stairs and Walls can also be crafted using a Stonecutter.
Is there a calcite mountain?
Mojang’s notes do not describe one. They name only amethyst geodes and the Ice Caves biome as places where calcite generates.
Is calcite in Bedrock Edition?
Snapshots are a Java Edition feature and the notes cover Java only, so we cannot say whether or when the new set reaches Bedrock.
