Vyse's neighbour, George Eumorfopoulos, had amassed a large collection of Chinese Sung, Korean and Persian pottery. These caught Vyse's interest, and he started experimenting in the Sung style. Nell, who had trained as a singer, had also studied German and French, enabling her to decipher 19th century works on early Chinese glazes and Charles to reproduce chun (an iron glaze used in Chinese celadon ware), tenmoku and T'zu-chou stoneware glazes. Their experiments with oriental glazes established that the blue in celadons was due to iron and not copper as had been thought. Their work was sold at Walker's Gallery in New Bond Street.
