How can I tell early “Worcester porcelain” from later “Royal Worcester”?

"Worcester porcelain" can describe Worcesterware made during various periods of ownership, including an early factory that began in 1751. The Royal Worcester Museum notes that porcelain production began in 1751 and highlights Dr. Wall's role in the field. Later, in 1862, the Worcester Royal Porcelain Co Ltd was founded, a major collector's line that sorts through the practice of marking "Royal Worcester" eras. One practical method, start with the mark, then confirm that the form and decoration are consistent with the expected period. Early pieces often tend towards 18th-century forms, Chinese-inspired decoration, and rare marks such as the crescent moon associated with early-period Worcesterware. Later Royal Worcesterware often shows crown marks, "Made in England," and clearer factory identifiers. For expensive items, consult a specialist or visit the museum's resource website.
