Is it possible to remove engravings on a wall, that is to say that if someone came along and 'chiseled' off engravings is it possible to make the stone appear aged as if nothing had ever been there using some sort of chemical technique or the like?

Sandblasting. It's how they remove graffiti.

What level of technology is available, and how deep are the engravings?

Technology is now and they are basically heiroglyphic-deep...

Yes, although the stone has to be chiseled off to remove a whole layer of wall and it's not immediate. You spray the wall with various salts of elements like manganese and iron to accelerate the aging process. Follow up by smearing it with local lichens pulverized into a yogurt nutrient base and in a couple of years it might look naturally old.

It might look reasonably authentic, but a forensic analysis would certainly show otherwise.

thanks all...it wouldn't be for forensic testing just if someone came up and looked at the wall again that it would look the same just no engravings...cheers
