Hmmm. I'm not finding it as such. However "anor" translates as "sun" in Sindarin and Noldorin according to https://eldamo.org/content/search/search.html
and "naur" into "fire" in Sindarin and "flame" in Noldorin. So it translates as "sunfire."
Meanwhile, "mor" translates as "darkness, night" in Sindarin. I'm not turning up anything for the rest of that word (Mordarcer) but if contextually it's another material, it could be the dark equivalent.
