I've seen similar looking materials made up from layers of auto paint. Not saying that's what this is, just that it exists.
Being in and around Detroit, back in the 60's one of the members of the local gem and mineral group was a painter for Ford, that was when they did it the old fashion way with a human, spray gun and the hard lacquer paint. The frame carts that the bodies were painted on had to be cleaned every so often as the paint build up would get an 1"or 2" thick. He would bring out the chunks, as they used muffler chisels to chip it off. Think of Spectra -ply multi colored wood blanks.
He made lapidary style cabs, bolo slides etc. he also sold the rough by the pound at the local rock shows. It was .25 to.75¢ a pound. He called it Mustang agate. Depending on the color layers some was great looking and some were not so good.
Last year a member of the local group sold a couple of small sections he had it was by the ounce and was a couple bucks per ounce, man who knew. In the late 60's/early 70's people from Chevy and Dodge were selling it to.
Since they switched to a form of electrostatic application of the paint and dipping. the collection and cleaning of the racking system has been eliminated. :frown:
It really would make interesting pens, if you had pieces large enough to tun through the layers.
