I want to know the answer to the following question:
What material is used in order to release the vinyl records from their molds?
All the background I'm provided with is that "The production of shellac records continued until the end of the 78 rpm format (i.e., the late 1950s in most developed countries, but well into the 1960s in some other places), but increasingly less abrasive formulations were used during its declining years and very late examples in truly like-new condition can have as low noise levels as vinyl.". Is that enough to answer the question?
Answer: no
