Identifying the stone on my Eastlake sideboard?
I just acquired a nice mahogany (I think!) Eastlake sideboard. The top of it is stone, but I'm not sure what kind it is. I'd like to identify it so I know what to clean it with. It also has a broken corner, which I'd like to reattach.
Can anyone tell me what kind of stone this is? It's INCREDIBLY heavy, if that means anything!
Here's the whole sideboard:
Also, does anyone have any product recommendations for cleaning/polishing products and an adhesive to reattach the broken corner with?
