Crystal Memory
Crystal Memory is an IndustrialCraft 2 storage crystal that records a single item or block pattern for the Replicator's matter-duplication system.
Description
Crystal Memory acts as the data carrier of the IC2 replication chain. Place Crystal Memory in the bottom-right slot of a Scanner together with the target item, and the Scanner spends EU to read and write that item's pattern onto the crystal. Move the loaded Crystal Memory into a Pattern Storage to bank the recipe, then a Replicator rebuilds the item from UU-Matter using the stored pattern. A single Crystal Memory holds only one pattern at a time, and scanning a new item overwrites the old data, so keep a separate blank crystal for every item you plan to mass-produce.

How to use Crystal Memory in IndustrialCraft 2
-
1
Craft Crystal Memory (raw)
Place 5 Silicon Dioxide and 4 Obsidian Dust in an alternating pattern on the crafting grid to produce one Crystal Memory (raw).
-
2
Smelt it in a furnace
Smelt the Crystal Memory (raw) with coal or any fuel in a furnace to harden it into a finished, blank Crystal Memory.
-
3
Scan a target item
Open a powered Scanner, place your item inside, and put the blank Crystal Memory in the bottom-right slot so the Scanner writes the item pattern onto it.
-
4
Store the pattern
Move the loaded Crystal Memory into a Pattern Storage to save the recipe permanently and keep the data ready for replication.
-
5
Replicate from UU-Matter
Feed the pattern to a Replicator supplied with UU-Matter and EU to duplicate the original item as often as your matter reserves allow.
A Crystal Memory keeps only one pattern at a time — rescanning a different item erases the previous data, so dedicate a separate crystal to each item you want to replicate.
