I installed a new toilet (bowl and tank) a few weeks ago. Everything
looked good, except that now I see some kind of flakes and particles
collecting in the bowl after every flush. It rather looks like wax
from the wax ring. Is it possible that somehow the wax ring is leaking
into the bowl. Does the water somehow flow backwards at the end of the
flush. It looks that way, because the water level first drops and then
comes back again.

I have looked very carefully and there are no particles collecting in
the tank.

Could I have done something wrong in the installation. I am assuming
that the wax ring failing could be quite nasty. I have not caulked the
toilet down to the floor yet. As far as I can see there is almost no
gap between the toilet and the floor, and the toilet is not rocking at
all.

Dust, plaster from the interstices of the bowl? Was it, for example in
storage a long time before sale?
