Lasimainen

Lasimainen is a Finnish adjective meaning glass-like or glassy. It is formed from the noun lasi (glass) with the suffix -mainen, which indicates resemblance. The term describes surfaces or textures that are smooth, shiny, and often transparent or translucent, similar to glass. It can refer both to physical properties, such as transparency and a glossy finish, and to visual appearance.

In geology and mineralogy, lasimainen describes textures that resemble glass, including volcanic glass or rocks with a vitreous matrix. These materials typically lack crystalline structure and tend to fracture conchoidally, producing smooth, curved surfaces. In materials science and everyday language, lasimainen is used to characterise coatings, plastics, ceramics, or metals that look or feel glassy—highly polished, clear, and reflective.

Usage notes and nuances: lasimainen emphasizes the aesthetic or optical quality of glass-like appearance rather than asserting that the material is truly made of glass. It can be applied to surfaces such as polished metal, lacquered wood, or glassy finishes on ceramics. The term is distinct from lasinen, which more directly means “made of glass” or “glassy,” and from lasittunut, which can mean glazed over or coated in glaze.

In summary, lasimainen describes something that resembles glass in appearance or texture, spanning everyday language and scientific descriptions while conveying a sense of transparency, smoothness, and shine.
