A sourced snapshot of the automotive paint history behind Fordite, with dates and context that are easy to cite.

What this page covers
Fordite is not a mineral. It is hardened automotive paint buildup from older factory processes, cut across its layers and polished to reveal the pattern inside. The public record is limited, so this page stays deliberately narrow: it shares only details supported by a named source.
For a collector, the most useful takeaway is not a price estimate or a promise of rarity. It is a clearer way to understand what a Fordite piece can preserve: color, process, place, and time.

Fact 01
997
A factory contact quoted in GIA's 2016 Fordite report said that a one-inch-thick specimen could contain about 997 paint layers. It is a reported example from that factory, not a universal measure for every piece.

1 in.
The 997-layer figure describes a one-inch-thick Fordite slag specimen. A finished cabochon or pendant is only a selected cross-section of that original buildup.

1940s
GIA reports that Fordite was first collected at Ford Motor Company in Michigan during the 1940s, tying the material to an earlier era of automotive paint production.

1960s–70s
According to GIA's 2016 report, material saved from the 1960s and 1970s often carries the boldest color because vehicles in those decades were painted in brighter palettes.

2016
The Gemological Institute of America documented Fordite from the Corvette Assembly Plant, describing repeatedly baked automotive paint buildup rather than a natural mineral.
Source: GIA, 2016Method and source
This page uses the Gemological Institute of America's 2016 report, “Fordite from the Corvette Assembly Plant”, as its primary source. The report identifies the material as repeatedly baked automotive paint buildup and includes firsthand factory context supplied to its contributor.
Where the report describes a specific example, such as the roughly 997 layers in a one-inch specimen, this page presents it as that specific example. It should not be treated as a measurement for every factory, era, or finished piece.
