Abstract

Mine colorate non cotte ottenute formando una composizione di miscela da un agente di carica, un agente colorante, un legante e simili senza usare cera o simili, aggiungendo una sostanza repellente l'acqua/olio alla composizione di miscela, impastando la miscela con un solvente e/o un plasticizzante, estrudendo il materiale impastato, facendo essiccare gli articoli estrusi per rimuovere il solvente e/o il plasticizzante da essi in modo da formare pori aperti a causa della minore bagnabilità della sostanza repellente l'acqua/olio, e quindi impregnando gli articoli porosi con un olio, un grasso e/o una cera e procedimento per la preparazione delle medesime.
