I don't think that there exists any proof that allows to declare if a specimes was sandblasted or not.
Anyway, in this sample flow-lines a still clearly visible. |

In photos 2 & 4, the sandblasting removed the crust along preexisting 'contraction cracks.' There are still a few small spots of clay remaining.
I would not say it is definitively any better or worse than a natural specimen. The red-stained crust usually preserves flow-lines. Here they have been removed in favor of a darker-coloured crust.
The alteration should simply be noted...

To me it doesn't matter whether it was cleaned one way or the other. What does matter though is that it is a beauty! |

@Tom, @Paul: I do not know if there was done any kind of treatment like sandblasting or ultrasonic cleaning on this individual. I received it in that state as it can be seen on the photos. But there are still some very small spots of the reddish clay on the surface. Maybe a few words with respect to the provenance: I acquired this specimen in the 90s from Rolf B*hler (Swiss Meteorite Laboratory, Glarus, Switzerland). |

Very funny Paul! I don't think there is such a thing as an immaculate Milly, so I think this one has been overly cleaned, one way or another. |

Tom - maybe, but how can you be so positive it was sandblasted? Perhaps ultrasonic cleaning would do the trick. Perhaps it is an Immaculate Milly. |

This specimen has been sandblasted to remove the natural red clay. |

Super nice piece! You don't too often see a Millbillillie that has 100% dark fusion crust without the reddish clay on part or all of the specimen. This has nice thumb-printing and flow marks from flight. Beautiful! |
