also this,softening stones with plant extracts
And I'm still searching......
Excellent - that second link is exactly what I was looking for! Thankyou.
From the second link..
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 article states that they experimented and found a solution containing acetic acid, oxalic acid and citric acid the most effective and that large
quantities of these could have been produced by the ancients using common plants such as "Fruits, Potatoes, Maize, Rhubarb, Rumex, Agave Americana,
Opuntia, Ficus Indica and Garlic to name a few."
I definitely recommend anyone interested in this to read the short article in the second link above.
