Terrazzo

I want to make a terrazzo tabletop. I was in the marble & granite industry
around 10 years ago. We never installed terrazzo. How do I pour a terrazzo tabletop approx. 32" square. Set forms etc, but what is the mix of portland and sand . I  also want to color the portland mix and add glass and stone
chips.I know a local marble company that can polish it with a slab polisher will that work with the glass in the mix.? Will diamond pads polish the edges as
well ?
