Abstract

L'invention concerne une porcelaine colorée à aspect granulé obtenue par injection, notamment la porcelaine à usage quotidien, la porcelaine hygiénique, la porcelaine ornementale toutes obtenues par coulage sous vide ou par coulage à matrice. Les granules présentent deux couleurs différentes, un diamètre variant entre 1 mm et 50 mm et une granulométrie oscillant entre 50 et 50.000.000. Le procédé de fabrication consiste à préparer des grains colorés, une pâte, à obtenir une préforme et à la cuire. L'invention permet d'obtenir une préforme tridimensionnelle et une surface ornementale montrant un motif de granules de granit 100 %, ce qui donne à la porcelaine un aspect fini semblable au marbre, granit ou jade gravé sur l'article et lui confère une apparence brillante et somptueuse.
