Abstract

It is well known that most protein substances may be hardened to form relatively hard, tough, and water resistant materials by suitable chemical treatment. Perhaps the oldest application of this type is the tanning of leather. Much more modern and of much more popular appeal is the production of some 10,000 tons casein annually to be made into such items as buttons, buckles, fountain pens, and various novelties in an attractive array of pastel colors. While milk casein, hardened by formaldehyde, makes excellent plastics the casein is higher in cost than some available proteins so that the possibility of using other proteins has been given considerable study.
