I suspect that this is the case when talking about coated papers, such as
the glossies you get in magazines and such. Newsprint is probably a
different type of animal. Mostly pulp with far fewer fillers. I worked in
a paper mill before going off to college...don't remember mixing any kaolin
in the common newsprint, but there was plenty of it, railroad carloads of
it, that went into the paper made for the likes of Time and Newsweek. Of
course that was in 1969...technologies may have changed radically, and my
memory could certainly be faulty.
Why not go to your neighbors that burn wood for heat or in their fireplaces,
give them a metal ashcan, and offer them a pot or two if they'll collect
their ash for you and burn it without adding all kinds of garbage and other
stuff.

Matt wonders...
What would you guess about plain white office paper?
It is not glossy, so I am guessing that it probably would be mainly paper,
and not be coated. Do you think plain white office paper contains much
kaolin?
I live outside Washington, DC. We don't have any sawmills nearby, but by
golly we got tons of office paper! If I could figure out a way to burn it
successfully...
I recently wrote to Lowell Baker about adapting his sawdust burner design to
use shredded paper. He raised this issue of the clay coating. If white
office paper isn't clay coated, shredded paper might be a useful fuel.
There certainly is an unlimited supply around here. Mostly it just ends up
in the trash. Most business don't recycle their paper unless the local laws
require it.
Could be an interesting experiment.
