I want to know the answer to the following question:
In addition to wool, what is uranium salt a mordant of?
All the background I'm provided with is that "Uranium was also used in photographic chemicals (especially uranium nitrate as a toner), in lamp filaments for stage lighting bulbs, to improve the appearance of dentures, and in the leather and wood industries for stains and dyes.". Is that enough to answer the question?
Answer: no
