A method of modifying a substrate comprising an etching step comprising contacting one or more primary surfaces of a glass, glass-ceramic, or ceramic substrate with a solution for a time period of 20 minutes to 8 hours to generate one or more etched primary surfaces, the solution comprising over 10 percent by weight of one or more alkali hydroxides, the solution having a temperature within the range of 100 C. to 150 C., the substrate having a thickness between the primary surfaces that decreases during the time period by 5 m to 100 m at a rate of 2 m per hour or greater. The solution of the etching step does not comprise hydrogen fluoride. The one or more alkali hydroxides of the solution of the etching step can be sodium hydroxide (NaOH), potassium hydroxide (KOH), or a combination of both sodium hydroxide and potassium hydroxide.

The present invention is a decorative member that is attachable to an outer surface of a vehicle, the decorative member including a glass plate that has a first main surface that faces an outer side of the vehicle, and a second main surface that faces an inner side of the vehicle; and a plate-shaped support member that is attached to at least the second main surface of the glass plate and is made of a resin material, in which the support member is configured to be attachable to the outer surface of the vehicle.

The application relates to bond materials for a grinding wheel, in particular a glass ceramic and a preparation method thereof, and a bond for the composite grinding wheel. The glass ceramic is prepared from raw materials comprising kaolin, silica, diboron trioxide, lithium superoxide, albite, potassium feldspar, talc, dolomite, phosphorus pentoxide, and yttrium oxide. A glass ceramic composed entirely of microcrystalline phases is obtained from the glass prepared by the above raw materials at 900-1020 C., achieving a complete conversion of the glass phase at a low temperature. The application also provides a bond for a composite grinding wheel, comprising glass ceramic and glass with mass ratio of (20-50):(50-80), the glass phase having a low flow temperature and, together with the glass ceramic phase, forming encapsulation of the abrasive particles, realizing low-temperature sintering of the grinding wheel. Microcrystalline phase in the bond results in high mechanical strength for the obtained grinding wheel.
