Ford F-150 Fordite
Fordite, also known as Detroit agate or Motor City agate,[1] is old automotive paint which has hardened sufficiently to be cut and polished.[2]It was formed from the buildup of layers of enamel paint slag on tracks and skids on which cars were hand spray-painted (a now automated process), which have been bakednumerous times.[3] In recent times the material has been recycled into jewelry.[4]
