Given we know she can manipulate molten glass(to forge her weapons on the fly), and she even used it to reform the arrow she melted around the sheild in Pyrrha's final battle, the simplest explanation is that she melted the arrow impaled in Pyrrha's chest and split it like a super-fine molten cheese-grater, splitting her cells which then immediately incinerated as their smaller mass then succumbed the heat her maiden powers created to melt the Obsidian.

Why couldn't she do this to start? Aura, Before Pyrrha had it, but after the arrow to the chest she didn't.
