Throne of the Inca - Vitrified Steps at Sacsayhuaman - As Smooth as Glass


Throne of the Inca shows heavy signs of vitrification on many surfaces. These vitrified stones form some of the broad steps that lead up to the top platform, altars, and niches undoubtedly used for ceremonies many centuries ago. An added unique feature is the discovery that these stone steps that show evidence of vitrification are also quite magnetized.


Of course, over the millennia since these areas were constructed, the weather has eroded much of the stone surfaces. This partially destroyed some of the vitrification that may have been evident on most platforms and steps. Some of the larger stones with weights over 100 tons have been altered significantly by what appears to be the application of high heat. Some of the megaliths are split, have changed texture, or their colour has been altered from the original natural state. Vitrification is visible on stones in a more protected spot. It is possible that some of the damaged stone work occurred when the parts of the building fell down due to earthquakes, time, and the effects of extreme weather events. However, the evidence that extremely high degrees of heat contributed to the problem leave some historians mystified.



Also, on the Rodadero hill, archaeologists discovered a tunnel with the vitrified stone ceiling and walls. Additional tunnels and natural cave parts show mirrored surfaces that reflect light easily. Erosion has opened some of these tunnels to the weather since they were built in ancient times. This helped researchers discover more about the extensive network and experience the vitrification in more obvious ways. However interesting the tunnels are, there is no real evidence that clearly shows what they were used for.
