PROBLEM TO BE SOLVED: To provide a glass capable of optical structuring with a combination of crystallization and etching by light exposure without devitrification during melting and molding, a method for structuring the glass and a structured product obtained by structuring.SOLUTION: There is provided a glass capable of optical structuring containing Siof 45 to 65 cation%, one or more kinds of crystal actuation body of 30 to 45 cation%, one or more kinds of crystal antagonist of 3.5 to 9 cation%, and one or more pairs of nucleating agents. There is provided a method for providing the glass to an etching step after irradiating glass ultraviolet light capable of being structured, where a. the crystal actuation body is selected from Na, Kand Li, b. the crystal antagonist is selected from A1, B, Zn, Snand Sb, and c. the pair of the nucleating agent contains cerium and at least one kind of agent selected from a group of silver, gold and copper. There is provided a product structured by the method.SELECTED DRAWING: None 【課題】溶融、成形時に失透せず、露光による結晶化とエッチングの組合せで光構造化が可能なガラス、および該ガラスを構造化する方法、構造化により得られる構造化された製品、を提供する。【解決手段】Ｓｉ4+を４５〜６５カチオン％、１種以上の結晶作動体を３０〜４５カチオン％、１種以上の結晶拮抗体を３．５〜９カチオン％、および１つ以上の成核剤の組を含む光構造化が可能なガラス。ａ．前記結晶作動体は、Ｎａ＋、Ｋ＋およびＬｉ＋から選択され、ｂ．前記結晶拮抗体は、Ａ１３＋、Ｂ３＋、Ｚｎ２＋、Ｓｎ２＋およびＳｂ３＋から選択され、ｃ．前記成核剤の組は、セリウムと、銀、金および銅の群からの少なくとも１種の剤とを含む、構造化可能なガラス紫外光で照射したのちにエッチングステップに供する方法。該方法により構造化された製品。【選択図】なし
