How flat is a granite worktop?

If that slab is only supported at the outer edges I would be very careful what you put on the top as it won't take much of a knock for it to crack.!

Its supported around the perimeter, but inset about 10cm.

No where near mate,you need to fully support it no matter what you will use on it.

I asked my mate who makes counters from Granite and quartz about using quartz unsupported and said wouldn't recommend it, just one tap in right place and it could shatter like glass. Apparently, it can crack under its own weight if wide enough and not supported well enough.
