I'm sourcing a new sink for my kitchen.

I had virtually decided on a 'granite' style from Carron Phoenix
(rather stark but indestuctable) until I saw Focus now stock an
attractive white ceramic sink called Rustica from CP for about the
same price. (Strangely the Rustica is not listed on Carron Phoenix
own webpage)

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?
