1. A method for producing a part in a form of a solid block, from a natural material in a particulate form containing scleroproteins, comprising, carried out dry:
a phase of heating the natural material under compression at a pressure greater than or equal to 30 MPa and at a temperature greater than or equal to a denaturation temperature of the scleroproteins to obtain a denatured material; and
a phase of cooling the denatured material to a temperature less than 100° C., the compression at the pressure greater than or equal to 30 MPa being maintained for at least a part of the phase of cooling.
