Issue Title

It says "Solid Casings dictate Chemical Plant tier", but there's nothing to say what this does.

Expected Behavior

The next line should tell us what the tier does presumably.

Possible Solution

Add tooltip text.

Context

I have no idea why I would upgrade from steel to anything above that.

Game Environment

GTNH 2.0.8.3

Misc Info

Check all that apply ([ ] -> [x] - use a lowercase x)

•    Using GT:NH/GT:New Horizons?
•    Single Player?
•    Multi Player?

Look at the recipes in NEI, they’ve got a tier tooltip.
