(1) Enough CaO in andesite. According to one poster it's like 6%. If it was 20 % or more, the rock would become like a soup when treated with acid..
5.2% not enough. You know that really.
(2) Vitrification (ie,
giving it a gloss) is possible by applying acids. Fact: They still use that nowadays.
These people say otherwise. Proof needed to contradict them. Show me where acid vitrifies granite please.

(3) There are enough plants in Peru and the Amazon jungle that have more than enough acid. The problem is finding out which one of them the Incas used. The plant we are looking for may be standing in front of your window.
Speculation and no proof. As you say "the problem is......." (that's a big problem).
Davidovits has already proven it. He was able to mold rock by using plant acids; I posted a link to his paper a couple of times. We are here only talking about chemically altering the
outer layer of rock (granite and andesite), or your 'vitrification
No proof. Plus the moulding goes very deep. My pictures proved that. Your ignoring key evidence.
(4) No need to penetrate quickly.
So how long does your chemical take to act on rock to completely soften it? Heat can do that. Chemicals? Never.
(5) No need to treat it. Just pour the liquid over a finished rock, and every hole and crack will be 'vitrified'.
The problem I identified was the quantity needed. Are you proposing that they dipped 50 tonne blocks in an acid bath to soften them? The pock marks and mould marks go deep and all over the rocks in some cases. How could they be coated if not dipped in a bath?
You have posted several photos of accurately cut stones, stones of which even a blind man can see they have been pounded on with some rock giving its surface a zillion tiny dents.
You conveniently skipped past those posts where I asked you about it.
Pure conjecture. No proof that the precision blocks at Sacsayhuaman and Cuzco were pounded. Far more evidence exists that they were moulded. I have provided many pictures that prove this. You have produced none to show that they were pounded. The Inca walls definitely were. Not the precision ones. You have never attempted to explain the mould marks.
The burden is on you Abe. You have provided no evidence. I have provided ample.
