Hello, I have a roughly cutted Muonionalusta slice to make beatiful. I will grind, polishing and etching it ... and after for prevent rust and stabilize it I'm planning to use the method alcohol + water + NaOH . But I have few question:
Ethanol at 96% works fine? I have to use distilled water or normal water? For 100ml of solution I have to use 70ml of ethanol and 30ml of water, is this proportion correct? How many grams (or spoons) of NaOh I have to use? How many days I have to leave the slice in the solution? 7-10 days? In this period I have to change the solution or the first potion works fine for all these days? And after? What I have to do? I have to wash it with ethanol and after dry up in oven, 80°C? After could I also put some rust prevent varnish? Any other tip are welcomed!!! Thanks a lot!!! Francesco! ______________________________________________ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
