How to Craft Andesite Bricks, Tiles, and Pillars
From Andesite to Bricks
Andesite Bricks are the base block for the whole Andesite family. Place Andesite in a crafting grid to produce Andesite Bricks, then use those bricks as the input for the rest of the set. From Andesite Bricks you can craft Andesite Brick Slab, Andesite Brick Stairs, Andesite Brick Wall, and Andesite Brick Gate directly.
Tiles and Pillars
Andesite Tiles are a separate decorative branch. Craft Andesite Tiles, then derive Andesite Tile Slab, Andesite Tile Stairs, Andesite Tile Wall, and Andesite Tile Gate from them. For vertical accents, craft Andesite Pillar and Andesite Corner Pillar. The plain Andesite Gate is also available if you want a fence-style opening without the brick texture.
Stonecutting Shortcut
If you have a stonecutter, feed Andesite Bricks or Andesite Tiles into it to produce the slab, stair, and wall variants more efficiently than grid crafting. Keep a stack of Andesite Bricks on hand as your master material — every other Andesite block in the set traces back to it, so you only need to manage one input.
