Granite Surface Plate - Cracked?

Also if you suspend and gently strike it with a plastic hammer it won't "ring" cleanly if it's cracked

Thanks Nick!

Not sure about this idea as its pretty heavy but I have used crack detector kits in the dim and distant past. Will do a search and see if I can find one that is suitable and fits within our budget ie cheap :)

Wouldn't accept it my self and send it back. I've never seen crack or defect in any new surface or lightly/correctly used surface plate that is designed to hold any sort of precision.!
