Lead is so important in making ceramics, there is nobody proposing to ban it. Instead, the main proposal is to require ceramics to be tested after manufacture to ensure that the dose of lead leached into any given food or drink is sufficiently low.
The main way that is achieved is by firing the ceramics at higher temperatures and longer to ensure the lead is better chemically bound to the rest of the pottery and leaches slower.
That sounds like very bad news to me. So now I have to trust whoever made the ceramics to not sacrifice this step, which I can't really check on my own.
This is based on making pottery as a hobby: Most craft potters working in earthenware use lead glazes as the colour response is more appealing than what can easilly be achieved with other low-temperature fluxes. It's also more resistant to crazing, and for earthenware to be functional it's important the glaze doesn't craze significantly as earthenware is slightly porous- if the glaze is crazed then your coffee cup will leave a damp mark on the desk.
