Minecraft Java 26.4 Snapshot 6: Snow Bricks and an Icy Sulfur Cube
27 Snapshot 6 was released on October for Java 26.4: new winter blocks, a sulfur ice cube and automatic memory setting.
Minecraft Java is getting even colder. On **October 27, 2026**, Mojang released **26.4 Snapshot 6**, a test build featuring winter building blocks and a mob that turns water into ice. Here are the highlights, without a lengthy list of technical fixes.
Snow bricks: how to craft
Four snow blocks arranged in a square of **2×2** turn into snow bricks. From them, slabs, steps and walls are available: you can build a fortress, a needle or a snow-covered city with neat masonry.
There are nuances: a stone cutter for creating snow slabs, steps and walls is not suitable, and it is necessary to extract the bricks themselves to save the block with a shovel**. New materials significantly expand the possibilities of winter construction.
Cold Sulfur Cube: Water turns into ice
A new kind of sulfur cube appears if the mob absorbs the blue ice. After that, he knows how to stay on the water and create a circle of frosty ice under himself - like the charm of "Icebreaker".
But this is not an endless ice factory: there must be free space above the water, and the cube must start moving while on the ground. But for test maps, ice arenas and unusual mechanisms, the idea looks promising.
Productivity changes and corrections
Java now automatically selects the amount of memory for JVM: up to **25% of the computer’s RAM**, but up to **4 GB**. This is the default value, not the universal recommendation for large modpaks.
Fixed departures at the opening of inventory, individual errors of ice caves and mob behavior. Bricks made of dense ice now require a pickaxe to produce a block. The ice crystals received atmospheric sounds.
How to install Snapshot 6
Open **Minecraft Launcher → Installations**, turn on snapshots and create a separate installation **26.4 Snapshot 6**. Do not run the main world without a backup: test versions can damage saves and are incompatible with some mods and server plugins.

Where to play Minecraft Java with friends
While testing snowbricks in a separate world, you can use **BlockRadar** Find Minecraft Java servers with the appropriate version, online and mode. Snapshot 6 support should be checked separately: snapshots are usually not compatible with stable version servers.
