The Radioactive Element: Uranium
The primary radioactive element found in some Fiestaware pieces is uranium. Uranium oxide was used in the glaze to achieve the bright, vibrant colors that Fiestaware is known for, particularly the orange, red, and yellow shades. The use of uranium in ceramic glazes was not unique to Fiestaware; many manufacturers during the early 20th century utilized this element for its color-enhancing properties. However, the discovery of its radioactivity has led to a significant decrease in its use in consumer products.
Why Uranium?
Before the risks associated with radioactivity were fully understood, uranium was valued for its ability to create a wide range of colors when used in glazes. The oxidation states of uranium allow it to produce different hues, from yellow and orange to pink and red, depending on the conditions under which it is fired. This versatility, combined with the durability and colorfastness it imparted to the glaze, made uranium an attractive choice for ceramic manufacturers.
Identifying Radioactive Fiestaware
Not all Fiestaware pieces are radioactive, and the presence of uranium is mostly found in items produced before the 1970s. Color is a significant indicator, with red, orange, and yellow pieces being more likely to contain uranium. However, color alone is not a reliable method for determining radioactivity, as some non-radioactive pieces may also exhibit these colors. The age of the piece is another crucial factor, with older items being more likely to contain uranium due to changes in manufacturing practices over time.
Testing for Radioactivity
For those concerned about the radioactivity of their Fiestaware, testing is the most reliable method for determining the presence of uranium. A Geiger counter can detect the radiation emitted by uranium, providing a straightforward way to identify radioactive pieces. However, accessing a Geiger counter or knowing how to interpret its readings can be challenging for the average person. Alternatively, consulting with a professional or a reputable antique dealer who specializes in vintage ceramics can provide valuable insights.
