Hello List, I have a nice 16.4g complete slice of Portales Valley with some large metal veins and fusion crust. Now I am thinkling about etching the slice to bring out the Widmanst�ten pattern in the metal. Is there anything special I need to care about when etching Portales Valley?
I have etched several of my iron meteorites, and even a large iron nodule in my 28g slice from the Estherville mesosiderite. But I have never etched a ordinary chondrite, so I though I rather ask... Would the experts on this list also recommend to lacquer the slice after etching? My slice is currently not covered with lacquer, and there is not the slightest amount of rust visible now. But can the acid make the iron start to rust? Is there any danger that the nitol used for etching or the alcohol used for cleaning the specimen would destroy the thin fusion crust? Thanks for your help, Herbert Raab Linz, Austria ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
