Material naturala , eraldatuak eta
                   sinetikoak
MATERIAL NATURALAK : Naturan dauden bezala erabiltzen dira , aldaketarik gabe edo aldaketa gutzirekin. (Harria , zura …)
 MATERIAL ERALDATUAK : Lehengaien hainbat prozesu fisikokimiko ezarrita lortzen dira. Horren artean , beirak , zeramika
                                                      …
    MATERIAL SINTETIKOAK: Metodo kimikoen bidez lortzen dira , oso propietate desberdinak dituzte beste material
                                                 batzuetatik.
