Hello List, This topic reminds me of the "Magic Cleaning Potion" we purchased from a hippie at the Denver show last year. We figured it was a combination of acids after accidentally reverse etching some Tazas with it. He was right this potion was capable of cleaning things. Not only did it etch our Tazas from the outside-in giving them a 3D appearance, it disintegrated a 2' square hole in our driveway after eating through a seam in a tin bucket. We can hardly wait to give this dude a piece of our mind this year as this potion gassed us out of our shop with a noxious brown cloud and damaged a bucket, ~ 400 grams of Tazas and our driveway. Be careful when using any type of acids to etch or clean with.

It is then diluted (by pouring acid into alcohol) down to "1 molar" (16:1 vol/vol), but in quotes because that should be with anhydrous, or 95% minimum ethyl alcohol....I usually consider "molar" as in water, hence the important clarification. > Doug > > careful and have fun drawing figures:) > ______________________________________________ > Meteorite-list mailing list > [EMAIL PROTECTED] > http://six.pairlist.net/mailman/listinfo/meteorite-list ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
