Further Metal Aggregate testing

The black iron shavings I used in my first metal aggregate casting test rusted as expected.  They were also very sharp and there was not enough of them to provide a powerful effect (though continued weathering over time will only enhance the effect).

For future tests I will use a finer consistency of metal that can be mixed into the concrete in greater quantities or can be used only at the surface of the concrete.  I will use copper which will be easier to see in an unrusted state and whose rust will be more dramatic.
