Luray Pastel Vintage Luray Dishes Safe?

Vintage Luray Dishes Safe? - luray pastel

I recently acquired a large collection of vintage cake plates Luray fifties. I am wondering whether to paint it a potential risk of lead. I was outside, they eat pretty regularly, but it puts them in the microwave or dishwasher. If anyone is information about the risks of lead in paint Luray courts are greatly appreciated. Thank you!
