PROCESS FOR THE PRODUCTION OF A CERAMIC ARTICLE

A process for the production of a ceramic article includes 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 to form a hot fused article; and (g) cooling the hot fused article to form a glazed ceramic article. The particulate mixture includes from 30 wt % to 80 wt % recycled aluminium silicate material. The particulate mixture has: (i) a d50 particle size from 10 μm to 30 μm; (ii) a d70 particle size of less than 40 μm; and (iii) a d98 particle size of less than 60 μm. Steps (c) and (f), and optionally steps (d) and (e) are continuous process steps.
