I have had the Pfaltzgraph Yorktown dishes for more than 40 years. In their literature, they say not to leave your flatware resting on the dishes, especially when sitting in the sink after using them. Over the years, I have picked up extra pieces both at their factory outlet stores (often seconds) and at yard sale and thrift stores. I cannot tell which are from the original set and which were added later. Now, if only I could find the cake pan I thought I bought!
