In an FOP 1, a glass body 8 is configured by including antimicrobial glass portions 10 made of antimicrobial glass containing Ag.sub.2O. Here, the glass containing silver does not have chemical durability, so that it has properties to easily emit Ag ions due to moisture. Ag ions have an excellent antimicrobial effect. Therefore, by configuring the glass body 8 to include the antimicrobial glass portions 10 containing Ag.sub.2O, the glass body 8 can obtain a sterilization effect due to the action of Ag ions. Therefore, the FOP 1 can be provided with antimicrobial activities.

A method for the production of blanks for sintered glass bodies for glass seals, wherein with a 3D printing method, a number of layers are arranged one above the other. In a first step, a first layer of a glass powder is spread on a surface, a computer-controlled stream of a printing fluid is directed to selected areas of the first layer in a pattern prescribed by the computer. In a second step, a further layer of the glass powder is spread over the first layer and on it, a computer-controlled stream of printing fluid is directed to selected surfaces of the second layer in a pattern prescribed by the computer, the two steps are repeated until the blank is formed. The glass powder components contain SiO.sub.2, Na.sub.2O, K.sub.2O, CaO, MgO, B.sub.2O.sub.3, BaO, Al.sub.2O.sub.3, PbO, Li.sub.2O and SrO as well as a solid binder made of dextrin.

A glass precursor gel and a method of making a glass product from the glass precursor gel are disclosed. The glass precursor gel includes a bulk amorphous oxide-based matrix that is homogeneously chemically mixed and includes 30 mol % to 90 wt.% silica and at least one of the following: (A) 0.1 mol % to 25 mol % of one or more alkali oxides in sum total, (B) 0.1 mol % to 25 mol % of one or more alkaline earth oxides in sum total, (C) 1 mol % to 20 mol % boric oxide, (D) 5 mol % to 80 mol % lead oxide, or (E) 0.1 mol % to 10 mol % aluminum oxide. A method of making a glass product from the glass precursor gel involves obtaining the glass precursor gel, melting the glass precursor gel into molten glass, and forming the molten glass into a glass product.

The invention relates to a method for producing a coated, chemically prestressed glass substrate having anti-fingerprint properties. The method includes: applying at least one functional layer to a glass substrate; chemically prestressing the coated glass substrate by an ion exchange, where existing smaller alkali metal ions are exchanged for larger alkali metal ions, and are enriched in the glass substrate and the at least one functional layer; activating the surface of the at least one functional layer, where if more than one functional layer is present the surface of the outermost or uppermost layer is activated, the activating including one of several alternatives; and applying an amphiphobic coating to the at least one functional layer of the glass substrate, where, as a result of the activation process, the functional layer interacts with the amphiphobic coating.
