Devoré techniques use blended fabrics which combine protein-based fibres (animal fibres) with cellulose-based fibres (plant fibres). In order to create the 'burnout' pattern, a chemical gel containing sodium hydrogen sulphate is applied to the fabric in patterns, dissolving away the cellulose-based fibres and leaving behind the protein-based fibres, which are not affected by the chemical.

This technique can also be used with combinations of fibres mixed with metallic yarns that literally can't be burnt away.
