Title (EN) GLASS HAVING FINE BUBBLES AND METHOD FOR MANUFACTURING SAME
(FR) VERRE AYANT DES BULLES FINES ET PROCÉDÉ DE FABRICATION ASSOCIÉ
(JA) 微小な気泡を含有するガラス及びその製造方法
Abstract:
(EN) The present invention relates to glass having bubbles wherein, when a cross section of the glass is viewed, the number of bubbles in the cross section is 1.0×102/mm2 or more, a diameter of the bubbles is 50 ìm or less, and an aspect ratio is 1.25 or less. This glass has good external appearance from any direction while having bubbles.
(FR) La présente invention concerne un verre ayant des bulles dans lequel, lorsqu'une section transversale du verre est visualisée, le nombre de bulles dans la section transversale est de 1,0 × 10²/mm² ou plus, un diamètre des bulles est 50 ìm ou moins et un rapport de longueur est inférieur ou égal à 1,25. Ce verre a un bon aspect externe depuis n'importe quelle direction, tout en ayant des bulles.
(JA) 本発明は、気泡を含有するガラスであって、前記ガラスの断面を観察したときの、前記断面における前記気泡の個数が1.0×10個/mm以上であり、かつ、前記気泡の気泡径が50μm以下であり、アスペクト比が1.25以下であるガラスに関する。本発明のガラスは、気泡を含有しながらも、任意の方向からの外観性が良好である。
