Brick Blocks are a decorative building block that does not naturally spawn anywhere. It is mostly used to make nice looking homes and towers. Since brick is non-flammable, it is often used to make fireplaces. Brick blocks are made by putting Clay in a Furnace and then crafting the Bricks in a 2x2 square. Brick is a durable block and resists explosions well. A pickaxe must be used to recover the resource of a placed block, but it will take under a second to break. Breaking a block with the players hand is slow and will not yield the resource.
Brick Blocks are used to craft Blulectric Alloy Furnaces and Mercurial Eyes. They are one of three option ingredients for crafting a Coal Chunk which is used to make Industrial Diamonds. Brick Blocks are also used to make patterns in the Filler.
