Motor City Aggate
Fordite also known as Detroit Agate or Motor City Agate.
Fordite, also known as Motor City Agate, is a unique automotive enamel material
with an interesting history. The original layered automotive paint slag “rough” was
made incidentally, years ago, by the now extinct practice of hand spray-painting
multiples of production cars in big automotive factories.
The oversprayed paint in the painting bays gradually built up on the tracks and
skids that the car frames were painted on. Over time, many colorful layers built up
there. These layers were hardened repeatedly in the ovens that the car bodies went
into to cure the paint. Some of these deeper layers were even baked 100 times.
Eventually, the paint build-up would become obstructing, or too thick and heavy,
and had to be removed. As the story goes, some crafty workers with an eye for
beauty realized that this unique byproduct was worth salvaging. It was super-cured,
patterned like psychedelic agate, and could be cut and polished with relative ease!
Wow! “RECYCLE IT!” seemed to be the resounding sentiment. And so it was…
As word got around about this remarkable material, it’s been said that rock hounds
started showing up at auto factories, offering to help remove that problematic
paint!
Sadly, the techniques that produced this great rough years ago, are no longer in
practice. Cars are now painted by way of an electrostatic process that essentially
magnetizes the enamels to the car bodies. This leaves little, or no overspray. The
old factory methods that created this incredible material are long gone.
The Fordite “mines” are dry, so get some while you still can!
