Thanks for expalining that! I thought I hadn't done the process right (5 days apple juice but ate the usual junk and should've waited for day 6 to do the olive oil mix). So I was disappointed there were no stones visible (I didn't use a collander for the mad dash to the bathroom). There was just the tan stuff with a few "moth wings". The rest was just sludge that as you say, burned like "HELL" and felt like red hot gravel stones.
