Among Boulton's most successful products were mounts for small Wedgwood products such as plaques, cameo brooches and buttons in the distinctive ceramics, notably jasper ware, for which Wedgwood's firm remains well known. The mounts of these articles, many of which have survived, were made of ormolu or cut steel, which had a jewel-like gleam. Boulton and Wedgwood were friends, alternately co-operating and competing, and Wedgwood wrote of Boulton, "It doubles my courage to have the first Manufacturer in England to encounter with—The match likes me well—I like the Man, I like his spirit."
