" This aluminum magazine was replaced by the well-known magazine featuring a body made of glass-reinforced, rust-colored, AG-4S cellulose resin. This was followed in turn by a magazine with a body of dark-brown butyrate plastic (also called ABS) of the type commonly used in appliance manufacture in the United States.

대충 베이클라이트가 아니라 유리섬유를 스깐 AG-4S라는 글

대충 해외에서도 왜 베이클라이트라 부르는지 모른다는 내용

대충 문과의 뇌로 이해해봤을 때, 기술적으로는 베이클라이트와 비스무리해서 그런가같다는 내용

사실 참조한 글들이 완전히 신뢰할 수 있는 글들이 아니라 정보 글로 올리기 좀 그런데 여러 곳에서 발암물질 베이클라이트는 아니라니 올려봤음
