The Alchemical Reaction Chamber, or ARC for short, can function as a Furnace, offers a form of Ore-Tripling, can revert Blood Orbs, Netherrite and Reinforced Runes, and is currently the only way to get Weak Blood Shards, specifically from a Saturated Tau.
Most tools used within the ARC degrade over time, but can be enchanted with unbreaking or mending to compensate.
The Sanguine Reverter is used to create Weak Blood Shards, and revert Blood Orbs, Netherrite and Reinforced Runes to their input crafting item.
All Reinforced Runes can be reverted in this way - this is just a demonstration.
Should you wish to automate the ARC, perhaps as part of an Ore-Tripling chain, you may want to know that it is sided, much like a furnace. Tools can only be inserted or extracted from the top, inputs from the sides, and outputs from the bottom. Keep this in mind when placing your Hoppers or Routing Nodes.
