PvP crafting materials are salvaged from PvP rewards using a PvP Salvage Kit. These materials can be used at the Mystic Forge to craft specific PvP items.
You can buy salvage kit and chests to salvage from the rank glory vendor.
Glory is a currency that players can spend on reward chests filled with random loot, while rank is a measurement of your total accumulated glory. As your rank increases, you unlock new tiers of reward chests, and thus access to more impressive looking equipment.
All PvP rewards are account bound, and can be stored in a collection in your PvP Locker. This means that even if you obtain items which your current character cannot equip, you can store it for later use.
All materials go into the PvP-Locker then you use "Deposit All Collectables".
