Perhaps add a scroll wheel to the crucible to prevent text rendering issues like so.
Alternatively have text resize itself when more metals are added.

Options I can see:

• some sort of scrolling (either just scrolling in the area, or a dedicated scroll bar)
• lowering text size (still has the issue, just less so, will also be increacingly unreadable as minecraft font scales in number of pixels.
• adding multiple pages. This is the option I think would be the easiest (because this is quite the edge case), least intrusive, and it matches the other gui that has this problem (skills)
