does anyone know about, chemistry, bircks and metals? Answered
umm, i was resently being bored with an arc welder (not a safe thing)
and amzed to find that if you put enough energy into a normal red brick that it will chemicly start to decompose,
it left a large area missing and with a grey almost glass like surface in the area with the most abuse, (this i can understand)
the thing that i found that was odd about this was when i lookd at the small colection of metal that formed when it cooled,
the main thing in it is iron (i was using an arc welder with normal rods and an iron rod) but i appears to have an almost flaking metal surounding it, its not impusitys that u normal get when weldin, it has an irridesent purple colour to it and is problaby made up from something in the brick.
