Do your glass walls have 2 surfaces each? When dealing with refraction, a
ray passes through a surface and with an ior and assumes itself to be
'inside' that material until it passes through another surface, therefore
glass or transparent objects need to have an actual thickness to appear
properly.   The refraction distortion on your glass appears as if this is
the case.  Where it passes through the 2 sides of the glass (i.e., the
bottom part of the bowl) it seems to be solid glass.
