    摘要: In production of artificial material for keys of musical instruments from two or more sorts of casein compositions of different colors, an oriented sheet including linear bodies made of at least one sort of casein composition and arranged in a given orientation is subjected to heat pressing followed by folmalin hardening in order to develop flowing deep stripes and massy impression on the product very close to natural ivory.
