Jon- I think you're thinking Pond's cold cream, not Noxema (which would be blue glass). But no-- that's a little scraper. Looks like chalcedony maybe? And yes- primarily to scrape and soften hides. Then comes the 'brain wash'. Good finds! Yakker
....thanks guys! That white scraper is "real stone" not "store bought"...honest.. lol I guess like yakker said some sort of chalcedony but very opaque...will post another maybe better pic.....
