Sintered Bricks in Once Human are a mid-game crafting material essential for constructing cement structures. Cement is the game's strongest building material, so you will need plenty of Sintered Bricks to upgrade your house and bolster your defenses for Territory Purification to farm Starchorm. Additionally, to stand a chance against the various bosses in Prime Wars — which scales up to Nightmare difficulty — you must build defensive structures using Sintered Bricks.
This guide covers everything you need to know to make Sintered Bricks in Once Human, including how to unlock the recipe and the materials required to craft them.
How to unlock Sintered Bricks in Once Human
To unlock the recipe for Sintered Bricks in Once Human, you must spend three Meme Points/Ciphers and 200 Energy Links in the Forging Techniques node within the Infrastructure tech tree of the Memetics system. This is a Tier 3 node located under Smelting Essentials and requires the Bronze Pickaxes node in Tier 2 as a prerequisite to unlock it.

How to craft Sintered Bricks in Once Human
To craft Sintered Bricks in Once Human, you will require three items: Gravel, Charcoal, and a Furnace. Gravel and Charcoal are among the first resources you mine and smelt during the game's tutorial, and a Furnace is one of the first craftable facilities.
With these resources, you can craft as many Sintered Bricks as needed to build a robust base and defensive structures in the Once Human's Prime Wars.
However, mining Rock with pickaxes and smelting Gravel in a basic Furnace is extremely time-consuming. Given the large quantity of bricks required to upgrade a base, this method is far from efficient.
Using an Electric Furnace and an Advanced Electric Drill can exponentially speed up the process. Additionally, an Electric Furnace eliminates the need for Charcoal when smelting Gravel. These advanced tools can also be unlocked in the Memetics tech tree.
Moreover, if you are lucky enough to get the Electric Furnace: Efficiency Lover Memetic Specialization or purchase its Memory Fragment from another player, activate it to significantly boost the speed of crafting large quantities of Sintered Bricks.
