附有皮膜的玻璃及其制造方法以及经改质的玻璃基材

本发明的目的在于提供一种附有皮膜的玻璃及其制造方法以及经改质的玻璃基材，所述附有皮膜的玻璃实现了如下：与水系内容物的接触角大、透明性高、润滑性(滑动性)优异、玻璃的二氧化硅成分不易发生剥离(分层)、来自玻璃的成分(硅、硼、钠、钾、铝)向内容物的溶出少、在适用于医疗用玻璃容器的情况下作为医药品的有效成分的蛋白质不易发生凝聚(吸附)、有耐热性、且皮膜的剥离得到抑制。本发明的附有皮膜的玻璃(1)具有玻璃基材(2)、及设置在玻璃基材(2)的至少一部分表面(2a)的皮膜(3)，且从玻璃基材(2)的皮膜(3)侧的表面(2a)直到规定深度(d1)的区域是改质层(4)，改质层(4)的至少一部分具有微晶结构。 An object of the present disclosure is to provide coating film-attached glass in which a contact angle with an aqueous content is large, transparency is high, lubricating properties (sliding properties) are excellent, the peeling (delamination) of a silica component in glass is less likely to occur, the elution of a glass-derived component (silicon, boron, sodium, potassium, and aluminum) with respect to the content is less likely occur, the aggregation (adsorption) of protein that is an active component of a medicinal product is less likely occur in a case where the coating film-attached glass is adjusted to a medical glass vessel, heat resistance is exhibited, and the peeling of a coating film is suppressed, a pr
