Els components pricipals de l'argila són els silicats d'alumini hidratats (Al₂O₃·SiO₂·H₂O) amb petites quantitats de Fe₂O₃, MgO, CaO,Na₂O i K₂O</p> <p><strong>Productes : </strong>Les fases cristal·lines son: Hematite, quars, corindó, clinoenstatite,òxid de potassi. Per vitrificar la ceràmica sovint s'afageix feldspat de potassi (K₂O·Al₂O₃.6SiO₂) que fon a baixa temperatura i es transforma en vidre.</p> </div></div></div></div></fieldset> <fieldset
