Resonant Crystal Blank is the unfinished form of the top HV crystal in Ala Industrial, a tech mod for Minecraft 26.2 Java Edition that runs on both Fabric and NeoForge. A crafting table yields one blank from four Resonant Shards in the corners, three Spatial Crystals across the top and sides, a finished Lapotron Crystal in the center, and an Energy Clot III in the bottom middle; the finished Resonant Crystal itself has no recipe. Resonant Crystal Blank carries a 1,500,000 EU buffer, accepts energy in any charge slot at 128 EU/t, and never gives a single EU back: the buffer is the manufacturing price of the crystal, not a battery.

A full charge takes about 9 minutes 45 seconds, because 128 EU/t is a hardware ceiling no charge slot in Ala Industrial exceeds. A Battery Box slot, a Reinforced Energy Storage slot, a Charging Station, a worn Energy Pack and a right-click Battery transfer all work, and chargers from other mods fill the blank as well. Once the buffer is full, Resonant Crystal Blank disappears and the finished Resonant Crystal takes its place — a plain item without a charge bar that later goes into the Workstation recipe. The crystal ladder climbs from Energy Crystal through Lapotron Crystal to Resonant Crystal, and since the blank is built around the finished previous rung, no step can be skipped.
