history: I like vinyl records more known as a Phonograph record. That's nice. Did you know that they are also known as record or gramophone record? Thats right, thats another term for it. Its an analog sound storage medium. Yeah, and the discs were common to be made from shellac What is shellac? I've never heard of it. shellac was once used in electrical applications Does it come from a tree. The vinyl's seem more of a plastic than anything so I assume it must be some sort of rubber. No its a resin secreted by the female lac bug, on trees in the forests in india and thailand Wow that is amazing how someone had the notion of creating vinyl's from a bug. Polyvinyl chloride became more common though in the 1950's.
knowledge: PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible.
