Questions & Answers about Die Hälfte des Kristalls wird blau.

Why do we use the genitive (des Kristalls) here instead of a partitive apposition, like we do with measurements?

Unlike units of measurement or containers (like ein Glas Wasser) which use apposition without changing the case of the material, nouns expressing fractions or portions—like die Hälfte (the half), ein Drittel (a third), or ein Teil (a part)—require the partitive genitive to show what they are a portion of.

Could I use von to say 'half of the crystal' instead of the genitive?

Yes, you can say Die Hälfte von dem Kristall. In everyday spoken German, replacing the partitive genitive with von + dative is very common. However, the genitive des Kristalls is the standard in written German and sounds more elegant.

Since des can be masculine or neuter, what gender is Kristall?

Kristall is typically masculine (der Kristall). It can sometimes be neuter (das Kristall) when specifically referring to high-quality crystal glass. Handily, both masculine and neuter share the exact same genitive form: des Kristalls.
