What are Setter Plates and Monolithic Boards made of?
Most of the Mattech boards are made from stacked FractalBalls. Alternately, the HMG1 or Alumina material is also available as plates and discs (which are not made from FractalBalls), and these are listed under Setter Plates and Monolithic Boards. Setter plates may also be used as membranes, as they have interconnected porosity.
