Fitzhugh
Spode used the name Fitzhugh, a name associated with Chinese porcelain patterns that had become popular in the United States near the end of the eighteenth century, to describe patterns that employed a trellis and diaper border used to accompany selected center designs. These center designs included one with four groups of flowers with objects surrounding a medallion-like design, and others with armorial devices and monograms. Today, the name Fitzhugh is commonly used to as an alternate name for Trophies Dagger.
felspar porcelain
Spode introduced "Felspar porcelain" to the market in 1821 when feldspar (modern spelling) was substituted for china stone in their standard bone china body. Production continued into the Copeland & Garrett phase of the company (1833-1847).
firing
Subjecting clay to heat, and fusing the clay to create pottery, different clay mixtures fire to different temperatures and create different kinds of pottery. Biscuit firing creates a stable piece of pottery Glaze or glost firing secures a shiny coating to the surface of a piece of pottery Decorative effects used in pottery often require additional separate firings
freeman of the city of London
No merchant might trade in London unless he had the freedom of the City, and only those approved by the relevant guild were granted that freedom. Since none but freemen could be elected aldermen, they controlled the city council which regulated all municipal affairs. Since the capital was also the centre of commerce, they dominated trade and industry throughout England. There was no guild for pottery or porcelain makers or dealers, so Josiah Spode entered the guild or livery company of the Worshipful Company of Spectacle Makers.
