Odd question he

I recently acquired several pieces of chem lab benchtop material from
a Freecycle board, with the idea of using them for -- something.

The question is, what are these slabs made out of? They are extremely
heavy and quite flat.

So far as I can determine, they are made of some sort of resin
material.

Does anyone know if this material can be cut and shaped with regular
woodworking tools?

Do I need a water-cooled cutoff saw?

Should I throw them in the river?

Start my own chem lab?

Any help greatly appreciated.
