Because Quark changes how ore generation works (making ores spawn in large, rare clusters rather than spread out), finding Corundum can be frustrating without the right strategy.
Quark allows corundum to grow on basalt when exposed to certain conditions. This farm exploits: quark corundum farm
Harvesting: Use Pistons triggered by the Observers to break the upper sections of the crystal. Because Quark changes how ore generation works (making
Vertical Expansion: A single Corundum source block will slowly grow a column upwards, up to 3 or 4 blocks high. rare clusters rather than spread out)
Layout: Place your Corundum Blocks in a row with at least 4 blocks of air space above them.
