Brick blocks are craftable building blocks. There are 3 categories: mudbrick, clay brick, and refractory brick.

Crafting

Mudbrick

There are 2 variants of mudbrick blocks: light and dark. These can be crafted using any combination of dry grass , clay , soil (low and medium fertility only), and sand . Mudbrick is fragile and has a 15% chance of being lost when broken.

Mudbrick blocks have 2 shapes: full blocks and slabs (half blocks).

Clay brick

For specific brick colors and patterns, see Ceramic Blocks .

There are 9 variants of clay brick blocks: black, brown, clinker, cream, gray, orange, red, tan, and fireclay. Raw clay bricks are crafted using 1 of 3 types of clay : red clay, blue clay, and fire clay. When fired in a pit kiln or beehive kiln , the brick’s color will change depending on its exposure to the outside air. Finished clay bricks can be combined with mortar to make clay brick blocks.

Clay brick blocks have 4 shapes: full blocks, slabs, stairs, and chimneys.

Fireclay brick

See also: Fireclay brick

Fireclay bricks are 1 of the 9 variants of clay bricks. Fireclay bricks lack a corresponding chimney, which is replaced by the bloomery . Fireclay bricks can also be crafted into gratings for use in a beehive kiln , and have a heat resistance of 50% (1 in 2 chance to break).

Refractory brick

See also: Refractory brick

Refractory brick blocks are used for building a cementation furnace and beehive kiln . There are 3 tiers of refractory bricks with progressively higher heat resistance, which reduce the probability of being damaged in a damage calculation.

• Tier 1: 90% heat resistance (1 in 10 chance to break)
• Tier 2: 95% heat resistance (1 in 20 chance to break)
• Tier 3: 99.9% heat resistance (1 in 1000 chance to break)

Unfired refractory bricks are crafted using fireclay , crushed quartz , crushed bauxite , crushed olivine (optional for tiers 2 and 3), and crushed ilmenite (optional for tier 3). A pulverizer with bronze pounder caps or a higher tier metal is required to crush these minerals. After firing in a pit kiln or beehive kiln , refractory bricks can be combined with mortar to make refractory brick blocks.

Refractory brick blocks have 2 shapes: full blocks and gratings.

Natural generation

Buried treasure chests found near the surface may contain red brick slabs, brown brick slabs, or fireclay brick blocks as loot.

Chests in ruins may contain fireclay brick blocks as loot. Underground ruins, specifically kitchens, may have a small amount of tier 1 refractory brick blocks or aged irregular brown brick blocks in the fireplace.

Purchasing

8 single clay bricks (red, brown, and fireclay) can be purchased from the building materials trader for 1 to 3 rusty gears . While in stock, this trade can be performed 6 to 10 times per reset.

Usage

Building

Mudbrick and clay brick blocks are solid, non-flammable blocks that can be used in player-built structures. Slabs can be placed horizontally or vertically. Chimney blocks will emit smoke and ember particles when placed above a firepit .

Fireclay brick blocks or refractory brick blocks can be used to build a beehive kiln , which is used to fire raw clay items . Refractory brick blocks are required to build a cementation furnace , which is used for steel making .
