  1. I have collected Blue Willow for 20+ years. I have recently found out that some may contain lead. Some pieces have no markings while others are from Japan, several different markings from England, and the USA. I would like to ensure that the pieces that are lead free are the ones we use for eating while those that are leaded are used only for display. Can you help?

    1. Hi Becky. In general I would not use Blue Willow pieces for food use. The likelihood of them being very high in Lead is too great. That combined with their age and regular daily use make them a definite Lead-exposure risk in most cases (in the absence of doing your own leach testing on each different plate.)

      Here’s a post about the overarching concern:

      Here’s the Blue Willow category on the blog with several relevant examples:
