I think the worry would be about how much a paper and crayon wears down the stone underneath (which the article alludes to with gravestone rubbings).
A damp sponge on top of aluminum foil still isn't contact-free, but I would guess it to be less of an impact than rubbing with a crayon. (It is also way more efficient to recycle aluminum compared to paper or wax).
- saagarjha 6y agoSurely because aluminum is extremely energy-intensive to extract from ore, not because its recycling process uses significantly less energy than paper recycling?
- dwohnitmok 6y agoIIRC almost all aluminum foil comes from recycled aluminum whereas most writing paper is virgin paper so the energy comparison is between aluminum recycling and paper manufacturing. I don't remember the numbers off the top of my head, but my impression is that paper manufacturing is quite energy-intensive as well. My bet is that recycled aluminum wins out.
