sawdust and theblood of slaughtered animalscattle andpig . It was invented (and patented) by Dr W H Dibble ofNew Jersey in the last quarter of the nineteenth century.Hydraulic press ure (40,000 psi) and chemical compounds, blood and sawdust were transformed by Dibble's Hemacite Manufacturing Company into everything fromdoorknob s and roller skate wheels tocash register buttons andtelephone receivers; there is even extensive use in Victorian jewellery.
