[3] This was a time of experimentation and technical innovation, when Japanese artists produced works more advanced than had been achieved before, which could not be replicated with modern techniques.
[2][5] Along with Hattori Tadasaburō, Kawade developed the moriage (盛上七宝 "piling up") technique which places layers of enamel upon each other to create a three-dimensional effect,[6][7] often used in depicting flowers or blossoms.
In 1911 the art historian Jiro Harada wrote that Kawade wasdeservedly considered the greatest enamel expert in the manufacture of shippo at the present time.
[...] He has been engaged in the shippo industry for the last forty years, and the advantage of his scientific knowledge and his indefatigable devotion to the work have enabled him to invent new colours in enamels.
One such work, executed by Kawade in 1906, was a pair of vases presented by the Emperor to the American cartoonist Henry Mayer, thanking him for cartoons on the Russo-Japanese War published in The New York Times.
