Solid Brass

It would be a solid bronze trash act as a Faraday cage good?

Given that the top is also covered by some type of solid metal? I wonder how to make an economic Faraday cage only one such case decides EMP pulses saturate my neighborhood, because of nuclear war. Also, as an addition would only be a simple tin biscuit tin (the kind with clowns and unicorns in it) work?

Only if there is a top of driving.
