Or you could try an offcut of polished plate glass, or even float glass - mine's 1/2" thick and dead flat!

I bought a marble floor slab (very similar to that in the picture) for exactly the same purpose that you suggest. I think it only cost a quid. I was very disappointed when I got it home and checked, it had a 10 thou dip in the middle!! I still can not work out how they managed to produce that effect. Maybe they tightened it in a jig prior to polishing and the jig was so tight that it distorted the slab. I have had more luck with a chunk of marble rescued from a marble kitchen work surface, they chuck away the piece that they cut out for the sink. I hope this helps.

For twenty quid, plus a fiver for p&p it sounds quite attractive! Does anyone have any experience of this good looking lump of granite? Is it flat? Does it scratch too easily?
