Lasilevys

Lasilevys is a term of Finnish origin that translates to "glass record" or "glass disc." Historically, it referred to a type of phonograph record made from glass instead of the more common shellac or vinyl. These glass records were produced in the early days of sound recording, often used for experimental purposes or by enthusiasts.

The fragility of glass made these records impractical for mass production and widespread use. They were susceptible to breaking and were generally more expensive to manufacture than their more durable counterparts. Despite their limitations, lasilevys represent an interesting early step in the evolution of audio recording technology. Examples of lasilevys can sometimes be found in historical audio collections or museums dedicated to the history of sound. Their existence highlights the continuous innovation and experimentation that characterized the development of the phonograph and recorded music.
