Abstract: Embodiments of this application provide glass and a preparation method thereof, a glass member and a preparation method thereof, and an electronic device. The glass includes glass phase layers that is located on a surface layer of the glass and includes no crystal, and a glass-ceramic layer that is stacked with the glass phase layers and includes crystals. In the glass according to the embodiment of this application, the surface layer of the glass is a complete glass phase, so that the surface layer has high ion exchange efficiency in a chemical strengthening process, which is conductive to stress enhancement of the surface layer. In addition, an interior of the glass is the glass-ceramic layer, which can resist a central tensile stress and crack propagation, so that the glass has both a high fracture toughness of glass-ceramics and a deep chemical strengthening stress of glass, and has excellent anti-drop performance.
