Designed for everyday use, the Cornishware 15 oz. mug makes a great collector’s item as it has great range that can take one from the breakfast table, to the office desk and beyond. Like Cricket and the Wellington boot, T.G.Green & Co.'s Cornishware's status is a cast-iron British classic evoking both pride and passion as a symbol of great ‘Britishness’ across the globe. First produced in the 1920's, the distinctive pottery owes its name to an employee who said it reminded them of the blue sky and white-crested waves of Cornwall. Adorned by millions and extremely prized by collectors, each piece if finished by hand, so there are natural variations in the color and glaze making each piece unique. Dishwasher, microwave and oven-safe, all Cornishware has a backstamp shield that is fired onto every item to ensure authenticity.
