How to fix a hole in vintage porcelain sink?
I love my vintage 1960's porcelain bathroom sink (photo #1) - original toilet matches it.
At some point in time I must have made a bone-head move and smacked the bottom of the sink with a wrench while installing a faucet. The resulting cracks have been visible for years but didn't seem to be a problem.
Then a year or so ago I noticed a chip out of the top surface, so I applied some sealant over it to try to protect it from the water. Unfortunately, that chip recently turned into a Hole that goes through the bottom of the sink (photo #2). When investigating the hole, under the sink, a couple loose chips of porcelain came off in my hand - bummer (photo #3).
I know all about preserving porcelain glaze and preventing scum and hard water build-up on porcelain and fixtures; but I don't know anything about Porcelain Repair. Is it possible to fix the chips and fill the whole to preserve my sink? Help!
