Hello, I have a question. As we know an iron meteorite, such like Campo del Cielo for example, have a black surface. I have here a deeply rusted Campo, I'm planning to remove rust with a sand blasting process. But with this I will obtain a greysh surface, like naked iron, the same color of a slice. Not really a natural color for the exterior of an iron meteorite and also not aestetically pretty, looks too artificial for me. There is something to do for restore the original black color? Or it's better to remove the rust with a traditional steel brush, maybe with a drill ???
Tips for mechanical or chemical process are welkomme!!! I can try with the classical NaOh bath, I have also Phosphoric, Citric and Oxalic acid :) Thanks <x>x<x>x<x> Francesco --- Questa e-mail è stata controllata per individuare virus con Avast antivirus. https://www.avast.com/antivirus ______________________________________________ Visit our Facebook page https://www.facebook.com/meteoritecentral and the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list
