Jar Label (Thaumcraft 4)
- This page is about the Jar Label added by Thaumcraft 4. For other uses, see .
The Jar Label is an item added by Thaumcraft 4. It is used to label Warded Jars and Arcane Alembics to allow only one type of essentia to enter the container. Placing a blank label on a container with essentia will automatically modify that label to the aspect inside. It can be pre-labeled by crafting a blank label with a filled Phial of Essentia; the Phial is not consumed in the process.
