    I recently made a RTV mold of some tree bark. I was molding some
    other items and had RTV left overs. Instead of throwing it away I
    poured it onto a piece of oak firwood that was lying around. Yes, it
    did penatrate into the bark and Yes, the bark did adhere. After
    curing for 36 hours I placed the RTV/bark item into the sonic cleaner
    overnite. The wood swelled and became soft and mushy. After breaking
    of the larger pieces, which at this point were easily removed, I
    steamed the mold to help remove the tiny particles still attached. I
    then repeated the process about three times. I now have a usable
    contact mold that I can lay up with hot wax to get a very usable
    representation of tree bark. Seems like great minds all think alike.
    How is it that I poured this mold just before this thread started?
