Interesting question and I have been asking myself the same thing...I just got done reading some doctors site that says that the stones are only an oil and mineral mixture.
The first stones I passed I left in a box in the drawer my bathroom and they turned into little lumps of coal...they did not melt away...but they did dry up into little rocks.
The flush from the other day...I was at work and I put them into a small plastic cup with water that I thought would preserve them...well they started to melt away throughout the day until I took them home and put them into the freezer...they instanty froze and retained their color and shape.
A person I work with said that when she worked for a surgeon...he had patients that they removed the gallbladder....he would often give them back their stones in a little jar...and they resembled little lumps of coal...exactly what my stones turned into after they dried out.
I have a big time question for those skeptics that say that the stones are made of oil....when I stored the stones in water and they did in fact start to melt away....THERE WAS NO OIL RESIDUE FLOATING IN THE WATER WHATSOEVER-----obviouse if I add water to an oil base I am going to get seperation...but their was no seperation at all.
Perhaps a skeptic could argue that for me...where is the oil when the stones melt away in water?
