FTB Jar Mod (Forge)

This mod adds jars that let you add custom recipes with KubeJS or datapacks. Supports both item and fluid inputs and outputs. Tempered Jars can be connected with tubes to tanks, chests and other item/fluid handlers. You can put Auto-Processing block on top of it to enable automation. The jar will stop if there's no room for outputs. 

The game will let you know, if you have missing items

Each type of temperature has multiple items that make it either more or less efficient
