David J gurgled happily, sounding much like they
were saying:

Now I thought that ceramic sinks were equally indistructable - a
lifetime guarantee is given. Then browsing through eBay I spotted one
for sale at a reduced price because it was 'chipped'.

So is a ceramic sink not as durable as I had expected?

A ceramic sink is relatively easy to chip. Probably not as easy as
stainless is to dent, but certainly not difficult.
