Abstract:
A process for the production of a ceramic article, the process comprises the steps of: (a) preparing a particulate mixture; (b) contacting the particulate mixture to water to form a humidified mixture; (c) pressing the humidified mixture to form a green article; (d) optionally, subjecting the green article to an initial drying step; (e) optionally, glazing the green article to form a glazed green article; (f) subjecting the green article to a heat treatment step in a kiln to form a hot fused article; and (g) cooling the hot fused article to form a glazed ceramic article, wherein the particulate mixture comprises from 30wt% to 80wt% recycled aluminium silicate material, wherein the particulate mixture has a particle size distribution such that: (i) the d 50 particle size of from 10μm to 30μm; (ii) the d 70 particle size of less than 40μm; and (iii) the d 98 particle size of less than 60μm, wherein steps (c) and (f), and optionally steps (d) and (e) are continuous process steps.
