My brother and his wife had their bathroom redone recently - more
recently a hairline crack had occurred in their sink, one of thse bowl-
shaped things sitting on a table base. He was wondering what he could
use to seal the crack, not necessarily to make it invisible, just
functional.
I haven't seen the place in ages and I'm not sure what the material is
- he said it's stone, but maybe it's some manmade composite, ceramic
or what...I imagine that would determine the fix.
He's still trying to figure out how the crack got there...doubts
something fell on it, wonders if a recent reroofing job might have
jarred some plumbing - a vent stack or something.

If it was recent, there might be a warranty.

The roof repair is likely unrelated.

Not knowing any more, it would be impossible to recommend a material or
method of repair.
