About this subject

The 78 rpm shellac record was the standard audio format from the 1890s to the 1950s, primarily made from shellac, a natural resin secreted by lac insects. Unlike vinyl records that spin at 33⅓ or 45 rpm, 78 rpm records required heavier styluses and wider grooves. Each side held only about 3 to 5 minutes of audio, restricting recordings to short songs and instrumental pieces. This format became the vehicle for the global spread of jazz, blues, classical, and popular music in the early 20th century.

Shellac records were fragile and heavy, typically black but also produced in red, blue, or green for special editions. Their production involved pressing a mixture of shellac, stone powder, and carbon black. Breakage was common, making well-preserved originals highly collectible. Legendary artists like Louis Armstrong, Duke Ellington, and Carmen Miranda recorded their early hits on these discs.

The shift to vinyl in the 1950s rendered 78 rpm records obsolete, but their legacy endures in museum collections and audio archives. Today, enthusiasts restore vintage phonographs and digitize these recordings, revealing unique sonic textures. The term "78 rpm" has also permeated pop culture, evoking nostalgia and vintage aesthetics.
