Why is a black surface a better emitter of IR than a silvered surface?

[Glenn G]

I can just get the idea of a silvered surface reflecting IR and a black surface absorbing IR (analogous to how light behaves) but I can't see how a silvered surface, if warm is a poorer emitter than a Matt black surface, if warm?
Would appreciate any help without going too in depth.
Regards,
G.

hi there

there's no point me typing out a long answer when some one else has already done so ...
