Abstract
A method for producing a part in the form of a solid block from a natural material in particulate form containing scleroproteins. A phase of heating the natural material, under compression at a pressure greater than or equal to 30 MPa, to a temperature greater than or equal to the denaturation temperature of the scleroproteins contained in the material. A phase of cooling the material thus obtained to a temperature less than 100° C., while maintaining the compression during at least a part of the cooling phase.
