Quicksilver is an old name for mercury, and mercury crystals look similar to aloxide crystals... Which is to say, no freaking clue but:

1. Report it (F8),

2. Enable console (in F3 menu, enable cursor with F8), open it (tilde I think) and type: item aluminumoxide 4,

3. Throw 4 (example) quicksilver things into the trash if you want to be fair.
