Widmanstatten patterns are formed by interwoven bands of kamacite and taenite inside of iron-nickel meteorites. These patterns can only form over literally millions of years of very slow cooling. It has been estimated that it took about 1,000 years for these meteorites to cool by just 1 degree Celsius! This video shows a time lapse view of the meteotite as a mixture of Nital (nitric acid and methanol) is applied to the meteorite.
