IRON METEORITE ETCHANT. The methods used to reveal the Widmanstätten pattern on iron meteorites vary. Normally the meteorite slice is ground and polished first, then cleaned to remove any residuals. The slice is then placed into Nital or an acidic ferric chloride solution. Since the nickel content of each meteorite varies, the time of etching. The distinctive Widmanstätten pattern (named for Count Alois von Beckh Widmanstätten, director of the Austrian Imperial Porcelain Works, in 1808), seen on some etched iron meteorite surfaces, is created by the interlocking crystal structure of two nickel-iron alloys (kamacite and taenite) Etching the Widmansätten pattern on Gibeon So we had a slight problem with our sample of the Gibeon meteorite. For reasons I won't go into, those marks (aka the Widmanstätten patterns) were polished off the surface of our sample Iron Meteorite: Detail of a polished and etched slice from a siderite (iron) meteorite found in the Brenham, Kansas strewnfield in 2005 by professional meteorite hunter Steve Arnold.

We have etched many meteorites over the years, in our opinion a lighter but detail- rich etch is preferable over a darker one. Additionally we use a very slow etching technique which brings out much more contrast between the different shades of gray present in a Widmannstätten- pattern, however, instead of a couple of minutes this process. You don't want so much current that the meteorite electrode is gassing or the bubbles will mask off the etching and cause pitting after a long period of etch. I do deep etching of 316 with a similar setup, ferric chloride on it's own won't touch it without the electricity assist. Positive terminal connects to the piece being etched These meteorites can be sliced and etched, revealing patterns of cross-hatched lines, called Widmanstatten figures. These meteorites, in ancient times, were considered as a prized source of metal for making weapons. Nickel-Iron Meteorite's high vibration intensity activates the kundalini channel along the spine
Iron meteorites with very little nickel called Hexahedrites will have no distinctive pattern when etched because only a single type of nickel iron mineral could form.
