La receta del esmalte es muy sencilla: 60% de cenizas y 40% de la pasta usada para construir la pieza. Luego le agrego un 8% de cualquier esmalte transparente comercial de baja temperatura.
Como no conozco la composición del esmalte (usé Crecer 701) , no está relacionado en la receta de abajo. Recordar agregarlo.
