I have a vintage divided serving dish.  It is glass.  It measures about 13 1/2"  x 9 1/2" across the top and sits 1 1/4" from the surface.  There are 5 shallow divided area's.  I did not feel/see any chips.  There are a few places where the white finish is worn off to show specks of black underneath - you have to look for this for the most part to see it, there are none that jump out at you, the largest is about the size of a medium tip pen.
