How to Identify Vinyl or Styrene Records: A Comprehensive Guide
Old post-shellac records can sometimes pose an intriguing challenge when determining whether they are made of vinyl or styrene. This article provides a thorough guide on how to identify these records through various inspection methods.
Visual Inspection
Even the most attentive visual examination can provide crucial information about the composition of a record. Here are the key observations:
Color and Finish
Vinyl records are predominantly black and exhibit a smooth, shiny surface. Styrene records, on the other hand, often appear slightly more matte and can display a more varied color scheme, including colored or translucent options.
Flexibility
One of the most reliable ways to differentiate between vinyl and styrene is to test the flexibility of the record. Vinyl records tend to be more pliable, making them easier to bend without breaking. Styrene, being more brittle, is more likely to crack or break when bent.
Weight
The weight of the record can be another telltale sign. Vinyl records are generally heavier due to their denser material composition. If a record feels unusually light, it might be made of styrene.
Audio Characteristics
While this requires the use of appropriate listening equipment, the sound quality can provide a subtle clue. Vinyl records are known to produce a warmer, richer sound compared to styrene, which tends to sound thinner or harsher.
Label and Catalog Information
Examining the record's label and catalog information can offer additional insights. Some record labels and manufacturers used specific materials for their releases, so researching these can provide clues about the material used.
Scratch Resistance Test
A simple scratch resistance test can further confirm the material. Gently scratching the surface with a fingernail can reveal that styrene is more prone to scratches and may leave noticeable marks, while vinyl is more resilient.
Proper Disposal and Usage of Vinyl Records
It is crucial to handle vinyl records with care, especially when considering their re-purposing. There is a concerning trend of people repurposing old vinyl records, particularly the thinner, more flexible LPs, to make candy dishes. However, this practice is highly discouraged due to safety concerns.
Health Hazard: When heated, vinyl records release toxic gases. These gases are particularly dangerous and cannot be easily neutralized by special recycling processes. Even crushing vinyl for recycling can release these harmful gases.
For proper disposal, old vinyl records can be used in creative and safe ways. For instance, vinyl can be used as building material, such as lining a chicken coop. However, it is important not to heat the record under any circumstances as this could emit toxic fumes.
Thicker, more durable vinyl records, such as 180-gram disks, are preferred by vinyl enthusiasts for their superior sound quality and longevity.
By understanding these methods and practices, record collectors and enthusiasts can better appreciate and care for their vinyl collections.
