Provenance History
Mass-produced in England for domestic use and international export (particularly to the North American market) during the turn of the century; likely passed through domestic household ownership.
Art Historical Significance
Represents the industrial expansion of Staffordshire pottery during the British Empire. Johnson Brothers was one of the most successful exporters of 'White Granite' or Ironstone, a durable alternative to porcelain that democratized high-quality tableware for the middle class.
Notable Features
Distinctive 'Royal Ironstone China' backstamp featuring the British coat of arms, used to signify quality and durability for the export market.
Condition Issues
Extensive 'crazing' (network of fine cracks in the glaze) and 'browning' or 'peppering' where oils and debris have permeated the porous body through the crazing lines. Minor surface abrasions and foot ring wear.
Conservation Recommendations
Avoid use with food due to porous crazing; clean with mild non-ionic detergents; store in a stable environment to prevent further expansion/contraction of the ceramic body.
