hey a friend of mine just redid his kitchen and has tons of scrap pesies of wood. and now seing my stove wants to give (dump) all the scrapes with me. is plywood ok to burn? it is glued together so im a little werry of accepting this wood. u know how it goes "oh u have a stove/ fireplace oh i have all this wood"......... i would think anthing with no glue would be safe right????
