I mean, Cinder used orange Dust to make black glass weapons, and it's possible they were specifically obsidian, which is volcanic black glass.

And she was using orange Dust in Volume 1 Episode 1, when she fired a shot at Glynda that splattered when Glynda blocked it.

And there were orange Dust crystals in the volcanic biome in the tournament, which had lava geysers.

So, there are reasons to support orange Dust being lava.
