Lusterware is pottery or porcelain that is fired in a kiln with a metallic overglaze for iridescence. Though luster was often applied in a "resist" technique, leaving certain areas of the piece unglazed for decorative effect, some of the most beguiling pieces were lustered in their entirety, adopting the look of the finest wares.

Depending on the color desired, platinum, copper, or gold was chemically dissolved and applied either by brushing or dipping. The unmistakable look of silver was achieved using platinum, while copper yielded a copper or brown look, and gold could achieve gold, pink, or lavender. It was noted that silver luster could be brighter than the most highly polished silver. With age and normal use, the glaze takes on the look of slightly tarnished silver, but the patina is not as dark and black as true silver tarnish.

The process of applying metal oxides to pottery dates back to the eighth century in the Middle East. But it wasn't until the mid-18th century that platinum was discovered, and the Spode factory in England became the first to apply this precious metal to earthenware. The product, known as silver luster or English luster, was unique to 19th-century England as a means of offering a more affordable "poor man's silver" to a broader market. Later, other factories such as Wedgwood produced the ware.

The most widely produced forms of silver luster in the early 19th century were tea and coffee sets, which were likely used only for formal afternoon tea. It is somewhat incredible that 200 years later, ceramic pieces with turned finials, scrolled handles, and sharply detailed spouts survive without damage and remain on the market.
