AFTER THE SPECIMEN HAS BEEN PROCESSED INSIDE THE CAPSULE WITH DESIRED FLUIDS, THE COVER IS REMOVED FROM THE CAPSULE TO FORM AN OPEN MOLD, THE SPECIMEN IS TRANSFERRED FROM THE OPEN MOLD TO AN OPEN-TOPPED BOX-LIKE BASE MOLD, AND THE OPEN MOLD IS PLACED IN COUPLED RELATION OVER THE BASE MOLD. MOLTEN PARAFFIN IS THEN POURED THROUGH THE OPEN MOLD INTO THE BASE MOLD. AFTER THE PARAFFIN HARDENS, THE OPEN MOLD AND THE RIGIDLY ATTACHED PARAFFIN BODY CONTAINING THE SPECIMEN ARE SEPARATED FROM THE BASE MOLD, AND THE OPEN MOLD IS MOUNTED IN THE HOLDER OF A MICROTOME FOR SUBSEQUENT SLICING OF THE PARAFFIN-EMBEDDED SPECIMEN.
