Established in 1830, the company was known for producing Royal Vitreous Porcelain dinnerware, tea sets, and toilet ware, with a reputation for intricate floral designs. Historical documentation from The Pottery & Glass-Brass Salesman indicates the company operated under various names over time: initially as J. Maddock from 1842 to 1855, then J. Maddock & Son from circa 1855 to 1870, and J. Maddock & Sons from circa 1870 to 1896. In 1896, it incorporated as John Maddock & Sons Ltd, suggesting that the absence of “Ltd” in the user’s description points to a manufacturing date before 1896. Given the user’s mention of “John Maddock and Sons” without “Ltd, ” it aligns with the period from 1870 to 1896, a common timeframe for their export ware marked with Ethe bowl was made by John Maddock & Sons between 1870 and 1896 in Staffordshire, England, based on historical records. Very large basin excellent in used condition.
