Thank you for your research.
I have full sets of:
Johnson Brothers Granite Fruit Sampler,
Johnson Brothers’ the Twelve Days of
Christmas, and
Spode Billingsley Rose
1. Do these three sets contain lead?
2.Are these dishwasher safe?
3. If they contain lead, should they be thrown
out?
I have the Mill stream Johnson Brothers plates and bowls in the color Blue. They look like their red ones you tested. Do the blue plates also have lead? Thanks so much!
Yes they do – Jonson Brothers dishes are not safe to eat off of. Here’s the full category of articles here to look through: https://tamararubin.com/category/johnson-brothers/
