14’40”) Marco posted these photos and it captured my attention. And these photos are of some of the oldest and most enigmatic Stone monuments in India. And they are perfectly Polished when you look at them. They’re made of sandstone and they are columns and they’re traditionally referred to as Ashoka’s columns and this was a 3rd century BC Buddhist King who inscribed his name on many of them with his edicts. Now Marco states that there were once at least 40 of these incredible columns that existed in various parts of India and as far away as Nepal, Pakistan and Afghanistan. Sadly, today just about 20 of them have survived and they’re in a reasonable state of preservation now.
16’03”) Now the craziest thing about these columns is that they display an unexplained smooth and shiny surface which is known as Marian polish. Now it should be noted that sandstone and Limestone cannot be polished to a mirror-like finish as displayed by Ashoka’s columns by any known abrasive method that we would employ today. So how did the Ashoka columns acquire their mirror-like finish and how have they retained their sheen for over 2,000 years if not far beyond that? Now some research suggests that the columns were covered with a mineral coating containing hematite inclusions, which is a magnetic mineral, and this coating appears to have been glazed or vitrified at extremely high temperatures to make it weather- and scratch-resistant.
17’35”) Now a similar technique may have been used to create these spectacular Barabar caves, ... a set of seven caves that were carved ... from solid Granite. ... These are from India as well. ... I’ll show you a photo here of Marco inside. It’s incredibly mirrorlike as well. So it looks like they were using some kind of a similar technique. And we also see vitrification like this all over in Peru. There’s an obscure cave just right above Cusco.
