Nitratine Dust

Nitratine dust is a buyable object. It is buyable in Liidhaga from Sindh's Alchemy. It is used in glass working to make the glass colorless, rather than its default faint blue-green color.

Ingame description:

This powdered nitratine is white, like chunky salt; its loose-packed mass is
unremarkable. It's very fine, like sand or dirt, and when properly mixed with
heated glass it should yield a colorless mass.
