Removing stone worktop

[Conan257]

As part of the renovation I'm doing of an older house, I need to remove the worktop from the kitchen.

It's some kind of stone, no idea what, and has the corners mitered and bonded in some fashion.

Any tips for breaking the join? Apart from just brute force? Whole thing is 7m long, so I'll never get it lifted without a lot of help

Yeah, it's 1m, then 4m, then 2m in a strange u-shape.

I'll try again levering it with the crowbar, maybe get the father to sit on one bit
