i have read here, most recently from eernest4, that you can stoke your stove with all kinds of wood junk, including stuff which is painted lacquered, liquoured, glued, and who knows, even upholstered. we are not talking of putting this stuff in a cat, of course. but someplace else - maybe a site about operating a masonry stove - they said to be real careful not to put in anything except for usda grade AA wood - you know what i mean, the stuff that trees are made of, au natural. becasue of strange heat, weird particulates, free radicals, i don't know. what's the story here. recycling wood junk into heat seems a nice green thing to do. will it ruin oa stove or masonry heater?
