Stone softening

FIrst post on this Forum for 2018.  Not expecting much traffic.  But anyways, have been very intersted in stone softening for a couple years now.  Fascinated by the prospect and am interested if there’s any people who have building experience and have fallen down the rabbit hole on this? 

Alot of stuff in Peru is very convincing, but from a building efficiency standpoint, really any megalithic work  where its polygonal design, or at least, as in the great pyramid, is  construction incorporating tight seamed work on non similar stones is really enough.  Or I should say is either proof of a stone softening approach, or that these ancient engineers had a terrible case of OCD combined with being glutton for punishment, and had the construction effiency intelligence of an 8 year old.   I have a hard time believing anyone who thinks our ancient relatives with the same brain size, would suffer such illiogical construction approaches. 

I am not a fan of geopolymers as an explanation for these examples of megalithic seeming 'softened stone’ work.   And I am certainly not believing the copper chisles and pounding stones ideas.   I believe the bosses or knobs support the stone softening approach, as well as several other aspects that would require images. 

Happy to discuss if there’s any interested.  Cheers.

Stone softening

I remember reading, somplace and quite some time back, about a bird the made it’s nest in stone cliffs. It woul rub some sort of leaf on the chosen spot. It took alot of leaves but eventually the stone started to ‘rot’ and crumble away.

The person that wrote the article suggested that the the pre-columbian Americans used this method, along with stone tools, to so finely fit their ‘building blocks’.

 

i do remember

they are called cliff swallows and they use leaves and grass and other stuff for the nest for the eggs. and they make their bird house out of “mud”. and after a while the mud does break apart and crumble. you are right though about ancient cultures using mud to seal joints in masonry, stone construction. we call that “mortar”. i remember that documentary on the show called “Nature”, it is on tv just before Nova. in the 30 years i have been in the construction i have used natural stone, man made stone, concrete block, bricks, wood. sometimes i use mortar, someytimes just dirt, and sometimes nothing at all as the man made blocks are designed that way. i have visited many historcal places and it is obvious their construction methods and materials have not change that much.

stone softening

I know about cliff swallows and so did the person writting the article. The birds they were speaking of were different. What made them stand out, in their mind, was that they formed holes in the cliffs by rubbing with the leaves and then pecking like wood peckers at the rock. They claimed that the nests ended up being 4 to 6 inches deep  into  the cliff face. They actually did make a comparison about the similarity between cliff swallows, weaver birds and these birds.

I’ve read about the many

I’ve read about the many claims of some chemical plant based ‘stone softening’ thing.  Not it.  Its a reach.   There’s no visible evidence of a chemical change to the stone.  And there’s an implied gradual activation level and depth to the affect.  It would be a tech we can’t explain.  But the evidence I'm referring to which is in so many places around the world, have a degree of precision that, if considered as a result of the projection of our modern approach to building, would make riparianfrstlvr’s 30 years of construction experience seem like a sad waste of time.  no offense.   The architectural evidence demonstrates that if they needed to, they could have banged off hundreds of same size blocks which would in our experience, make building far easier.  And yet they made stone structures with all different sized stone pieces.  No big thing there, but then they have seam gaps that appear to have a fraction of a mm in tollerance.  Zero chance that was done by hand, especially with any blocks that were big.   If you start down the road of high level CnC work that falls apart too.  Too much work.  To high a level of precision in part rather than in whole.    If you were to CnC all the pieces of the ascending passage in the great pyramid with CnC, there would still be a cumulative error issue in assembly.  They built huge stone structures easily, and with the stone softening tech, it removes most of the pre visualization necessary for a large engineering project.   Yada yada.
