Ultra Condense
by nouxinf
Ultra Condense lets players compact storage blocks such as coal, iron and gold blocks a further step, so one block holds far more material.
What it does
The mod adds 19 condensed blocks that are crafted from nine of the blocks that already exist in the game, such as redstone blocks and iron blocks. Each new block stores more items per slot than the block it is made from, which lets a player keep a large amount of material in a small space. Crafting goes back the other way as well, so nine vanilla compacted blocks can be recovered from one condensed block.
Some of the new blocks replace the materials used in vanilla recipes. A quartz storage block can be crafted from nine nether quartz, and the condensed equivalents can be used in place of the usual mineral blocks when powering a beacon. The mod is intended for players who store large quantities of ore and minerals and want fewer chests and shulker boxes.
Ultra Condense is published for NeoForge only, for Minecraft 1.21.8, and it runs on client and server. Both the server and every player need it. The mod is released under All rights reserved and is not open source.
Key features
Further compacted blocks
Coal, copper, diamond, emerald, gold, iron, lapis lazuli and netherite each gain a condensed block that stores more material than the vanilla compacted form.
Nine-block crafting
Condensed blocks are made from nine of an existing compacted block, such as redstone or iron blocks, in the same crafting grid pattern players already know.
Reversible recipes
Each condensed block can be crafted back into nine vanilla compacted blocks, so no material is lost when a stock is reorganized.
Beacon and quartz recipes
Condensed equivalents can power a beacon in place of mineral blocks, and nine nether quartz can be crafted into a quartz storage block.

How it compares
Compressed Coal is also a NeoForge storage mod, published for 1.21 – 1.21.10 under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, and it runs on client and server. Better Than Coal is another NeoForge option for 1.21.4 – 1.21.8, with the same client and server environment and the All rights reserved license. Ultra Condense covers only 1.21.8, so players on other versions should look at the wider-range alternative.
