My Wife has 5 Emma Bridgewater mugs. All, to varying degrees, have crazed. 2 or 3 to a point where she doesn't like to use them. As they don't look clean. Given the price of these items and the time they have had to perfect their manafacturing processes I have to say we are more than disappointed. As these are of different designs and purchased as different times it cannot be assumed that this was a faulty batch. On reading their website you need to quote order numbers etc. in order for their customer services to respond which we cannot do as these were all purchased for her as presents. I have left 1 star as no stars is not an option. Needless to say we will not be purchasing anymore products from EB. Buyer Beware!
