Brenham, Pallasite, Lot of 3 Slices, 3.81g

$20.00

Brenham is a pallasite meteorite that was first recovered from the rural farmfields of Kansas in 1882. Over the years, hundreds of individuals and fragments have been recovered. It is a metal-rich pallasite with some pieces that almost entirely metal. It is also known for having large olivine (peridot) crystals.

I recently acquired a large slice of this meteorite. The slice was "sick" from being improperly stored for many years in a humid environment. The beautiful slice still had many fresh-looking olivines and lots of unoxidized metal, but it was absolutely shot through with rust veins and some sections were falling apart. Without immediate conservation, this slice would eventually decay into a pile of rust flakes and loose olivines.

This slice was quickly broken down into sections (no further cutting) and mechanically cleaned to remove all surface rust. The pieces were then baked in a hot oven for many hours to purge any residual moisture trapped inside the meteorite. The slices were then removed from the oven and allowed to cool in a controlled, low-humidity environment. Once cooled, the specimens were lightly treated to retard future oxidation. If now properly stored, these specimens will be stable and suitable for collecting and display. 

Refer to the photo. The black centimeter cube is shown for scale and is not included. You are purchasing the specimens shown. This is a lot of 3 (three) small part slices that weigh a combined 3.81 grams. You get all three of them. Your purchase will include a labeled gemjar for safe storage.
