This is one of a series of 11 articles published here on LeadSafeMama.com with specific XRF test results for the various colors of modern Fiesta Tableware Company dishes (manufactured/ sold/ available in 2022). An overview article is also available here, discussing the findings for all of the colors, as well as the implications of and concerns for the metals found. Here’s another link to the FIESTA category of articles on this website, which include test results for both vintage and modern options.

Note: At one point (in the past decade), Fiesta brand dishware had the words “Lead Free” embossed into (or printed on) the bottom of each of their dishes along with their logo/ back-mark. I believe that once the company became aware of the fact that there was (in fact) trace Lead in some of their glazes and substrates (possibly based on the findings of Lead Safe Mama, LLC) they removed that language (both from the dishes and from some of their marketing materials).
