Wedgwood's best known product is jasperware created to look like ancient cameo glass. It was inspired by the Portland Vase, a Roman vessel which is now a museum piece. The first jasperware color was Portland Blue, an innovation that required experiments with more than 3,000 samples. In recognition of the importance of his pyrometric beads (pyrometer), Josiah Wedgwood was elected a member of the Royal Society in 1783. The Wedgwood Prestige collection sold replicas of the original designs as well as modern neo-classical style jasperware.
