Vintage Tableware Party, is it safe?

Hello, I know the Red / Orange Party Ware pre WWII days had lead in ceramic … However, the other original colors like green, yellow, cobalt blue, ivory ….. it is safe to use? I purchased some parts, and wondered if it would be safe to put in the microwave or eat out. Any Fiestaware collectors who know .. I would appreciate any comment. THANKS!

Do not put it in the microwave! There is a pen test lead is available in hardware stores and even Wal-Mart. It is like the pen used to test money. The ink turns on whether there lead in the test subject. Verification in the paint department. Or search online.
