Crafting and Building with Black Argillite in Born in Chaos
Black Argillite in Born in Chaos is a versatile dark masonry material crafted from subterranean clay, deepslate, and quartz to construct fortress walls and illuminated lamps. While players often rely on standard stone variants for construction, argillite introduces deep charcoal textures tailored for gothic spires, catacombs, and dungeon renovation. Mastering its compounding, kiln firing, and architectural stonecutting unlocks a comprehensive suite of building blocks.
Compounding and Kiln Firing
Synthesizing raw Black Argillite requires blending earth, sedimentary clay, and crystalline quartz on a crafting table:
- 1 Nether Quartz
- 2 Cobbled Deepslate
- 1 Clay
Mixing these ingredients shapelessly yields unrefined Black Argillite. In its unworked state, raw argillite can be crafted into basic architectural slabs, stairs, and discrete redstone triggers:
- 1 Black Argillite crafts 2
Black Argillite Button items. - 2 Black Argillite arranged horizontally craft 2
Black Argillite Pressure Plate items, which blend invisibly into deepslate flooring to trigger concealed traps.
To unlock high-durability masonry, place raw argillite into a furnace or blast furnace. Firing cures the mineral into 
Fired Black Argillite, the essential foundation for refined structural variants.
Masonry Variants and Weathered Textures
Using Fired Black Argillite at a crafting bench or stonecutter yields an expansive palette of building elements:
Black Argillite Brick: Arrange 4 Fired Black Argillite in a 2x2 square to craft clean masonry blocks.
Cracked Black Argillite Brick: Smelt standard argillite bricks in a furnace to simulate structural degradation and ancient age.
Mossy Black Argillite Brick: Combine argillite bricks with vines, moss blocks, or moss carpets to produce weathered versions.
Black Argillite Column: Stack 2 Fired Black Argillite vertically to produce upright decorative pillars, or craft 3 columns into 6 
Black Argillite Column Slab blocks.- Architectural Details: Utilize a stonecutter to carve bricks and fired stone into stairs, slabs, and defensive perimeter walls. Stonecutting yields two slabs per block, while stairs and walls maintain a 1:1 conversion ratio.
Assembling the Argillite Lamp
To illuminate dark corridors with matching fixtures, incorporate fired stone into an 
Argillite Lamp:
- 4 Fired Black Argillite positioned in the four corner slots
- 4 Glass Pane placed along the top, bottom, left, and right cross edges
- 1 Glowstone Dust secured directly in the center slot
The resulting lamp emits a steady, bright glow framed by reinforced dark stonework, making it an ideal ceiling lantern or courtyard torchpost for medieval castles.
