Hairline crack in ceramic sink

I had a call from a customer today. I'd fitted a ceramic sink for them a few years ago , it's the basin and drainer type. Seems he's dropped a saucepan into the bowl and there's now a hairline crack running across the bottom of the sink. It seems to be just in the glaze and there's nothing on the outside of the bowl and it's all still watertight. He's asked if there's anything that can be done with it before they go down the route of replacement. I did wonder if one of the enamel repair kits would work but have never used one so unsure if it would be suitable. Open here to suggestions.
From a quick google this is the first result

Not sure how obvious or invisible the results are...

Even Dentists have a job matching enamel colours, there are bath repair services, but at an expense, so a kit worth a try and use a sink mat protector; can use a contrast like charcoal.
My Son has also done the same damage to his one year sink!

His wife did say he should use a plastic bowl in the sink although that's a bit horse and stable door type of thing. I'll mention the repair kit to him , I suppose at lest than 15 quid it might be worth a try. If it works you can let your son know...

Ceramic sinks are like all pottery there is a fired bisque centre that forms the shape and it is then coated in a ceramic glaze which is then fired in the kiln. Invariably it is just the glaze that cracks and the bisque centre is fine so it is unlikely to leak, it is purely cosmetic. It is hard to match a glaze and even more so to hide the new finish. Just imagine repairing a white tea cup. It is cracked but does not leak.

Yes I know what you mean. The sink doesn't leak and probably never will. I think the crack taunts him for being clumsy. To be honest I'm not sure just how the stuff in my link works , there's not really any gap for it to fill so I suppose it must sit on the surface and whether that would be more obvious than a hairline crack I really don't know.

I called by to the customer yesterday to give him the results. I mentioned the kits available and like me he is wary of the reviews on the likes of amazon and also couldn't see how it would mend a crack without leaving a raised area. So I think the idea is going to be dropped but the suggestion of a rubber mat sink protector seemed like a good idea to him.
