Abstract

Método para la fabricación de productos de yeso, comprendiendo las siguientes operaciones: producir a elevadas temperaturas una mezcla líquida homogénea de pez y de una materia orgánica, no humedecible, que sea sustancialmente inmezclable en pez y se halle en estado sólido a temperatura ambiente, siendo la relación de la pez con la materia orgánica entre 25: 1 y 7 : 1; mezclar la mezcla líquida con yeso y agua para formar una pasta que tenga el factor correcto de absorción de agua, siendo el peso de la mezcla líquida igual a desde el diez al veinte por cien del peso del yeso hemi-hidrato, sobre una base de paso seco; darle a la pasta resultante la forma requerida; dejar que se solidifique la pasta formada; y calentar la pasta solidificada a una temperatura bastante elevada para fundir, tanto la pez como la materia orgánica, pero bastante baja para impedir el deterioro de la pasta solidificada.
