To be honest, all of the weapons are black glass. It's just that the spear and the swords she used at the Battle of Haven were also filled with fire. This is shown when she shatters the glass casing of the sword she uses against Jaune.

The difference is that the weapons she made in Volume 2 were made using Dust, whereas the ones after that were made with Maiden powers.
