Here's an alternative to cork, and also some high temperature adhesive to hold it in place. Seems to work quite well on my QiDi Tech 1.
Note: The pads are called "cottons" but are apparently not made of cotton. It is easily cut with scissors and the seller states that it's not flammable. When I tried burning a small piece on my gas stove it does slowly turn to ash, smells ugly, but does not sustain a flame.
