I bought an old college chemistry textbook at a yard sale for fifty
cents. When I opened the book to read it two small pieces of neatly
folded yellowish wax paper dropped out. They each contained a piece of
some type of metal.
The two metal pieces were clean grey strips about 8mm × 5cm. With
about the thickness of a piece of typing paper, the edges were sharp
enough to cut a finger.
The metal was somewhat hard but was bent easily like copper.
Wasn't attracted to, or repelled by a magnet.
It conducted electricity.
When put into the flame of a propane torch it expanded slightly, glowed
mostly white and a little yellowish, but did not melt.
After being removed from the torch flame the metal quickly cooled,
remaining intact without distortion. It had some very faint rainbow
colors on the surface where the flame had made contact. Presumably, the
colors were oxides of some sort. The metal was still easy to bend, no
brittleness from the heating.
Am wondering if the metal is Platinum.
Any ideas on what the mystery metal is?
