I read that article this week too and was dismayed. I'm still using my Corelleware that I got as a wedding present 51 years ago.
I ordered replacements in the white Corelleware. One can't beat the quality of these dishes. It makes me wonder why it took them to 2005 to stop using lead paint. The blue snowflake design was sentimental to me. I'll miss them.
I plan on offering the old plates to a neighbor who loves planting flowers in pots. They would be ideal to set a flower pot on.
