Unique science pack (or bottle/flask/beaker/whatever you call them) designs for each type so that they can be distinguished from each other on more than just their colour.

Changing the flask designs used

This mod uses Quality Glassware to source the flask designs the science packs are replaced with, you can override the flasks used by adding a comma separated list of <id>=<model>/<variant> to the Quality Glassware Overrides startup setting. For example to have the Automation science pack use a pyramid bottle, and Space science pack be an hourglass set Quality Glassware Overrides to automation-science-pack=pyramid/liquid_red, space-science-pack=hourglass/liquid_white.
