What you are getting is known as photolytic silver.
Papers designed for developing are not very efficient in
producing it because its not desirable in normal use. There
are ways of treating the emulsion to increase the effect, I
don't remember the details but might be able to find them.
My memory is that it involves treating the emulsion with a
solution of Silver Nitrate.
There is paper designed for this kind of printing
called printing out paper or POP. A paper made by Kentmere
in England was distributed in the USA as Centenial POP and
may still be available.
Another way might be to try one of the printing out
alternative processes, for instance salt prints. Salt prints
were common before modern "silver-gelatin" papers were
invented and can be quite beautiful. A Google search for
salt prints will get you a large number of hits including
some with instructions. A good site to get an idea of what
salted paper is is here:
