Are you a vinyl record aficionado concerned about the tiny bubbles often found on freshly pressed records? You're not alone. While bubbles in vinyl aren't typically a cause for alarm, they're a common occurrence that can raise questions about the record's quality and lifespan. But will these bubbles go away over time? The answer is a bit complex, as it depends on the type of bubble and several other factors.
The term 'bubbles' in vinyl records can refer to two main issues: pipette or delaminating bubbles. Pipettes are tiny, harmless bubbles that form due to trapped air during the manufacturing process. These usually fill with liquid vinyl and don't pose any threat to the record's sound quality or lifespan. On the other hand, delamination bubbles occur when the layers of vinyl in the groove separate, which can potentially impact sound quality and the record's longevity. Let's dive deeper into these two types of bubbles and understand whether they disappear over time.
Pipette Bubbles
Pipettes are common in new vinyl records and are nothing to worry about. They're usually tiny and barely visible to the naked eye. These bubbles form during the manufacturing process when air gets trapped between the two layers of polyvinyl chloride (PVC) that make up the record's groove. The trapped air doesn't create any issues with sound quality, and the bubbles often flatten out and become less visible over time as the record plays and the PVC softens.
It's also worth noting that some pressing plants intentionally introduce pipettes into the records to help prevent delamination bubbles. This process, known as 'ählange,' creates small, controlled bubbles that reduce the likelihood of more serious delamination issues. So, in this case, pipettes can actually help improve the record's lifespan and sound quality over time.
Do Pipettes Go Away?
While pipettes don't completely disappear, they do become less visible and less noticeable over time. As the record plays, the heat and vibrations from the needle cause the PVC to soften and the bubbles to flatten out. This process can take several plays, but it leads to improved sound quality and a reduced risk of delamination. However, pipettes may not be entirely invisible even after numerous plays, but their impact on the listening experience is negligible.
To encourage pipettes to flatten out, consider playing your records regularly. The heat and vibrations from the needle help to break down any remaining air pockets. Additionally, proper storage can prevent new pipettes from forming. Keep your records in a cool, dry place, away from direct sunlight and excessive heat, which can cause PVC to degrade and form new bubbles.
Delamination Bubbles
Delamination bubbles, however, are a different story. They occur when the layers of PVC in the record's groove separate, creating larger, more visible bubbles that can impact sound quality. Delamination is more common in older records or those stored in poor conditions (like extreme heat, cold, or humidity). While it can happen to new records as well, it's less common with modern manufacturing techniques.
Delamination bubbles can cause problems with sound quality, as they create gaps in the groove where the stylus can jump or cause a 'popping' noise. In severe cases, delamination can lead to significant degradation of the record's surface, making it unplayable. Unfortunately, delamination bubbles do not go away over time. Instead, they can grow larger and more pronounced, causing further damage to the record.
Preventing Delamination Bubbles
Since delamination bubbles don't go away, preventive measures are crucial. Store your records in a cool, dry place, ideally between 68-77°F (20-25°C) with a relative humidity of 45-50%. Avoid exposing your records to extreme temperatures, direct sunlight, or excessive heat, as these can cause PVC to degrade more quickly. Proper storage also includes using high-quality inner sleeves to prevent dust and scratches from compromising the record's surface.
Regularly inspect your records for signs of delamination. In mild cases, you might be able to flatten out the bubbles and improve sound quality using a record flattener or weight. However, if you notice large, pronounced bubbles or significant degradation of the record's surface, it may be time to contact a professional record restoration service. They can often remove bubbles and restore your record to playable condition, although they can't guarantee the original sound quality.
In the vast world of vinyl records, bubbles aren't always a cause for concern. Pipettes, the most common type of bubble, usually flatten out over time and don't impact sound quality or the record's lifespan. Delamination bubbles, on the other hand, require preventative measures and professional care if they do occur. By understanding the different types of bubbles and taking care of your record collection, you can ensure a lifetime of enjoyment and preservation of your beloved vinyl records. So, while some bubbles may go away over time, it's essential to prioritize proper storage and care to protect your records from the more serious issues that can arise from neglect or improper handling."
