Ran across this the other day, and I thought the glowforge could be a great application for this burgeoning technology: turning soot into printer ink. Apparently some students at MIT have been able to turn collected soot into ink. Maybe in the future, our glowforges will not only make cool stuff, but also refill our black printer cartridges!

Interesting. There used to be a brown paint called mummy ochre. I bet you can guess what it was made from. The producers ‘ran out’ of materials in the 1920’s and had to move onto other carbon based pigments. Lamp black paint used to be made with charred wood and bones.
And put that ink on paper home made from dryer lint.
