Vintage Fordite of the USA.  Nice thick pieces with lots and lots of paint layers!  

Vintage Fordite is also commonly known as Motor Agate or Detroit Agate.  It was produced during the process of hand spraying vehicles in large automotive factories in decades past.  The oversprayed paint 'slag' accumulated and created layers of colorful enamel that were cured and hardened at high temperatures in the manufacturing process - sometimes 100's of times for the deeper paint layers!⁠  When buildup became obstructive it was removed, thus creating the layered colorful chunks you see today.  

This hand spraying paint process for vehicles is no longer used.  An electrostatic method is now employed that creates very little overspray.  Vintage Fordite is a relic of our manufacturing past.  It is truly a one of a kind material. 

For the lapidarian, Vintage Fordite cuts and polishes very smoothly, creating famously psychedelic agate-like patterns.  

The metallic layers are indicative of vintage Fordite. It is the metallic layers that really make special cabs

We are showing a few example cabs we had cut from this same material for our Gem Dragon Auctions. They are always a popular item!
