Abstract
A container having an indicator for detecting the presence of chemical elements is provided. In one embodiment, the container comprises a cavity therein for receiving an article having a first metallic element, the cavity being substantially sealed from a surrounding environment outside the container. An indicator is disposed within the sealed cavity, the indicator having a second metallic element with a standard potential less than the standard potential of the first metallic element, whereby a change in state of the second metallic element alerts an operator to the presence of a predetermined chemical element within the container.
