That stuff gets confusing, at least to me. The molded button material
Gutta Percha has also been called bakelite, if erroneously. GP goes
back into the middle 19th century. Is there any relatively easy means
of distinguishing them? I've seen Gutta Percha buttons in black only
while the bakelite electric fixtures I've seen have all been brown. Is
it as simple as that?
