2005 EXPEDITION: YAMASH-I-T-A ( JAPS) TREASURE
Krugger, break of a piece of your suspect "rock" and put it in a pastic bucket. Cover it over with (fill enough to cover the rock) hydrochloric acid. In USA we would use bottled acid that is sold for using in swimming pools. A little hard to find in Mindanao but available in Davao, or just strong commercial HCL. If it is cement or cement mixed with decoy rock, in a couple of days it will all be dissolved. If it is real rock, it will still be there. If it is limestone or a calcite type of rock it will dissolve but not like a cement based object. Try a piece and let us know what you find.

may i know what is the difference of the dissolved limestone or calcite type of rock from the dissolved cement based object, using hydrochloric acid? is it the color? or the texture?, one more thing, there are some stories that upon pouring an acid on the stone, it immediatelly dissolved? how come immediately,,,is it hydroflouric acid they use?
Peace!
