Amazingly, a recent ethnological discovery has actually shown that some witch-doctors of the HUANKA tradition remarkably, use no tools in the making of small stone objects, but in fact still use a chemical solution made from plant extracts to actually soften the stone material!

According to Dr. Davidovits, in a paper that was written by Dr. Davidovits, A. Bonnett and A.M. Marriote and presented at the 21st International Symposium for Archaeometry at Brookhaven National Laboratory in New York, USA in 1981:

“The starting stone material (silicate or silico-aluminate) is dissolved by the organic extracts, and the viscous slurry is then poured into a mould where it hardens. This technique, when mastered, allows a sort of cement to be made by dissolving rocks; statues which could have been made by the technique of the pre-incan HUANKA, by dissolution followed by geopolymeric agglomeration, are found to contain Ca-oxalate in the stone.”
The trio then proposed the hypothesis that the large stones found in the Mayan Fortresses and monuments were in reality, artificial and had in fact been agglomerated with a binder after certain rocks had been slowly disaggregated, an idea that fits very well with what the walls look like and also happens to be in total agreement with local legends and traditions such as those that were told to Fawcett.

The group then even went on to present to the meeting some actual samples of stone that had dissolved and re-aggregated themselves to prove it!

“We present here the first results on plant extracts on the dissolution or dis-aggregation of calcium carbonate containing rocks (Bio-tooling action). The feasibility of chemically working calcium carbonate with various carboxylic acids found in plants (acetic, oxalic and citric acid) has been studied. Maximum bio-tooling action is obtained with a solution containing:
Vinegar (1 M) (acetic acid)
Oxalic acid (0.9 M)
Citric acid (0.78 M)
The great surprise was actually to discover very ancient references to their use since Neolithic times for working materials which are very hard but easily attacked by acids, such as chalk.
Thus, a bas-relief from the tomb of Mera, at SAQQARAH (VI dynasty, 3Millenium B.C., Egypt) shows the hollowing out of “Egyptian alabaster” (CaCO3) vases by a liquid contained in a water skin or bladder. An experiment of interest was to compare the “bio-tooling” technique with the shaping of a hole using a steel tool and the quartz sand technique recommended by prehistorians. The hole resulting from sand abrasion has rough walls, whereas bio-tooling gives a smooth finish.”

The work by Dr. Davidovits is nothing short of brilliant and also very refreshing. It’s also interesting to note how quickly the problem was solved once the right approach to dealing with it had been adapted.

There is now very little doubt about how the Ancients actually built these incredible structures and indeed, softened or perhaps melting the stone has always really been the only possible explanation. The ancient Mayans were indeed quite capable of producing very large quantities of the acids that were used by Dr Davidovits in his experiments from many plants that were quite common to the region in the distant past. Plants such as: Fruits, Potatoes, Maize, Rhubarb, Rumex, Agave Americana, Opuntia, Ficus Indica and Garlic to name a few.

It is highly feasible that the stones were quarried, then broken or crushed to manageable sizes for transportation to the locations and re-aggregated on site while being cast back into the megalithic slabs we now see, after all, since we have seen that they certainly had and knew about the means to do it, it somehow seems absurd to think they would not have made use of the knowledge.
