A house made of stone is naturally sturdier than one made of wood, and when it comes toOnce Human, you’ll want the most durable house you can get. Even if you aren’t worried about other players raiding your home, Deviation attacks are still a thing, and they can quickly destroy your property unless you upgrade to usingSintered Bricks
Sintered Bricks are an advanced building material that’s also used for a few other building recipes. If you want to reinforce your base orget into farming inOnce Human, then Sintered Bricks are going to be a necessity. Here’s how to make them.

How To Get Sintered Bricks In Once Human
Sintered Bricks are crafted in a Furnace, and they’re used to make many different stone structures. However, before you may start making them, you need to unlock theForging Techniquesmemetic node under the Infrastructure tree. This is a Tier 3 node, so you’ll need to spend both Ciphers and Energy Links to unlock it.
Once you have Forging Techniques unlocked, bring 10 Gravel and 3 Charcoal to any of your Furnaces at home. This will yield a single Sintered Brick. The good thing about Gravel is you can get it from miningany mineral inOnce Humanlike Tin, Iron, and Copper. Charcoal is pretty easy to gather in bulk as well — just chop down a few trees and turn them all into Charcoal at a Furnace, and you’ll be good to go for a short while.

If you’ve unlocked the ability to craft solar panels or bio-mass generators, then you may instead use an Electric Furnace to remove the Charcoal requirement. An Electric Furnace requires 5W of electricity to operate, so make sure to have enough juice flowing through your base so you don’t run out of power for everything else.
Best Way To Get Gravel
The best way to get Gravel for Sintered Bricks is to use an Electric Rock Drill, a power tool that you’re able to make once you unlock Electric Drills memetic node under the Infrastructure tree. Apart from giving you higher yields than normal compared to using a pickaxe, Electric Rock Drills also completely mine out ore nodes almost instantly. To craft one, you’ll need at least an Intermediate Supplies Workbench as well as the following materials:
You can find Aluminum by exploring level 30+ areas like Chalk Peak, and you’ll need to unlock the Aluminum Ingots node under the Infrastructure tree. Aluminum Ingots can only be made in Electric Furnaces.

Similarly, you canget Special Parts by collecting junk from high-level areas. Some pieces of scrap from regions like Chalk Peak and Red Sands can be dismantled into Special Parts. For best results, look in industrial areas like refineries, workshops, and garages.
As for the Storage Battery, you can craft it in an Intermediate Supplies Workbench using 15 Steel Ingots, 20 Rubber, 20 Acid, and 10 Electronic Parts. Unlock theElectrical Kitnode under the Logistics tree to get the crafting recipe for it.
