- This page is about the Void Jar added by Thaumcraft 5. For other uses, see Void Jar.
The Void Jar is a block added by Thaumcraft 5. It is an advanced version of the Warded Jar- when extra Essentia is pumped into it, it will simply be vented. Additionally, with a Label, it will pull in less Essentia than the normal Warded Jar.
Void jars function much the same as normal warded jars with one important difference - even when full they are still able to accept essentia, but the excess essentia is simply vented. This allows you to always have some essentia of that type available, but get rid of any excess that may build up.
Like normal jars, void jars can accept labels, but their suction with a label is less than that of a normal labeled jar (about halfway between unlabeled and labeled jar).
A word of warning: occasionally the venting process causes flux, but this is fortunately rare.
