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. In Tekkit, it is used to craft Blulectric Alloy Furnaces and Mercurial Eyes.
