have some small bonzai pots with plants in them that stand on a south facing
window ledge. The window ledge itself has a shiny tiled surface.

the pots stand on small ceramic saucers. these saucers do not leak water.
(one is glazed on its top surface so cannot leak ). but there always seems
lots of wet underneath them. is this some kind of condensation? or how
would it get formed ? thanks

You say one is glazed on the top surface, implying that it's unglazed
on the under surface and that the others aren't glazed at all.

If they are earthenware saucers, they will be porous and will allow
water to permeate, albeit very slowly, and condensation will appear on
any surface they stand on. The one with glaze may be crazed (a fine
crack pattern in the glaze) which will also allow water into the body
of the saucer, and you'll get condensation underneath as with the
unglazed ones.

You could try drying them out completely (put them in a warm dry place
like an airing cupboard for a few days (without their pots!), and give
the upper surfaces a coat of varnish. OTOH, if they're standing on a
tiled surface, the condensation isn't doing any harm, so why bother?

I had that with some saucers - When I put some fully glazed ones (old side
plates) underneath it stopped.
I guess the glazing was a bit porous (?)
