Yep,It's a disk of wax (or other materials) and fine grit used to grind concave mirrors, usually for reflector telescopes.
Yep, making mirrors(not lenses) for newtonian telescopes. It is a hobby of course and it is phenomenal that beeswax actually works. All of a sudden I can make a ton of polishing laps Usually mirrors are polished with gugolz and pitch but beeswax seems to be working well. I am still testing it.Is that something you do? Make lenses for telescopes? Cool.
They will collect propolis but collecting wax is really rare. I don't know if someone actually documented it ? ? ? Anyone ? It came as a surprise to me and to some beekeepers I talked. Collecting wax ?I noticed when I took off the queen excluder and had it sitting on the back patio, one of the girls came and started collecting the propolis off of it and storing in in her pollen basket just like in the pictures.
