Making your own ceramics can be a way to express your
creativity, but some techniques and materials used in the process
could spell bad news for your health and the environment. If not
prepared properly, some glazed ceramics can leach potentially
harmful heavy metals. Scientists now report progress toward a new
type of glaze that includes gold and silver nanoparticles, which
are less toxic and more environmentally friendly than currently
used formulations, while still providing vibrant
colors.
