Dans une cuve (22) de liquide, on introduit un liquide (21) séparateur de couche intercalaire contenant un agent tensio-actif, présentant une tension superficielle inférieure ou égale à 45 N/m, par ex. 35 N/m, et contenant des fibres végétales insolubles, par ex. du son ou des issues de riz, à une teneur inférieure ou égale à 5 % en poids, par ex. 0,1 % en poids, rapportée au total. Un verre feuilleté (10) dans lequel les plaques (11) et (12) de verre ont été broyées est introduit par une partie (23a) de couvercle dans une cuve (23) en baril. Des pièces métalliques carrées (25) (éléments d'accélération de la séparation) présentant une dimension de 30 mm × 30 mm et constituées d'un métal présentant un poids spécifique supérieur à celui du verre sont introduits au nombre de 50 à 300 par la partie (23a) de couvercle dans la cuve (23) en baril. Ladite cuve (23) en baril dans laquelle le verre feuilleté (10) et les pièces métalliques (25) ont été introduits est plongée dans le liquide (21) séparateur de couche intercalaire contenu à l'intérieur de la cuve (22) de liquide pour immerger ainsi le verre feuilleté (10) dans le liquide (21) séparateur de couche intercalaire. La cuve (23) en baril est mise en rotation à une vitesse de rotation donnée.
