The Inert Thaumium Cap is a cap added by Thaumcraft 4. It must be crafted into the Charged Thaumium Cap via an Infusion Altar before becoming suitable for wand creation.
Thaumium is known for its ability to store and absorb magic, so using it to craft wand caps is a logical choice. It is very efficient at focusing vis of all types.
Crafting these wand caps in an arcane worktable is not sufficient - they need to be infused with additional magical energy to make them usable.
