have some small bonzai pots with plants in them that stand on a south

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

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 (?)
