I am building a melter that is about 28" X 28". For a wax pan i was planning on a bread pan. With the width of the glass that I got was wondering if I could make a mold out of wood. What I was thinking about is one similar to a soap mold that can be taken apart to remove the wax. I know it will stick the first time around but my question is will the wood eventually obsorb to the point that it will pop out.
