The Glacidite Ore is an ore block added by Glacidus. It generates in Frozen Antinatric Stone around layers 84-85, in veins of up to 5 blocks. 20 veins are generated per chunk, but only stone horizontally adjacent to Glacium is turned into the ore.
When mined with a pickaxe with a mining level of 2 or higher (Iron Pickaxe or better), it drops 1 Glacidite Fragment. Fortune has no effect on the drops, while mining the ore with a pickaxe enchanted with Silk Touch will drop the ore block.
