Seating a wobbly bath sink

What kind of sink? Vessel, self r****ng, undermount? What material porcelain on steel, stone, ceramic?

Silicone caulk to plumbers putty is used. Might only need to tighten the hardware.

Thanks.

Appears to be a plain ceramic bowl sitting on a composite cabinet. No hardware holding it down, just the weight of the sink.

Looks like the previous owner or original installer placed some kind of green colored putty/sealant under the sink.

Double sinks. One does not wobble. The other one does. Not a big thing but aggravating.

Thanks.
