10. Radioactive Plates and Cups (Vintage Fiestaware)
Vintage dinnerware, especially brightly colored pieces like Fiestaware, may contain hazardous amounts of radioactive materials. In the mid-20th century, some manufacturers, including Fiestaware, used uranium in their glazes to create vibrant colors, particularly the signature orange and red hues. While the radioactive content is usually low, prolonged exposure to these items—especially if they are chipped or cracked—could lead to increased radiation exposure. Over time, this can pose a risk to your health, particularly if you use these plates and cups regularly for food or drink. If you own vintage Fiestaware or other similar dinnerware, it’s wise to retire them from regular use and consider displaying them as collectibles rather than using them for meals. Always be cautious of vintage dinnerware from this era and check for any warnings regarding its safety.
