First, craft some bottles from the Vessels mod, then make some dye base:
Craft six empty bottles along with a bucket of water and a piece
of jungle grass to get 6 portions of dye base.

These craft/craftitem definitions for glass bottles are deprecated and are
only included here for backwards compatibility. Use vessels:glass_bottle
instead.
