Slip Casting with Plaster Molds - In Six Steps

For classroom use, this video shows step-by-step how plaster molds can be used to make forms out of clay. This process is called slip-casting. For simplicity's sake, I am boiling the process down into six main steps.
*Edit: At the time I made the video, I did not realize that potter's plaster is different from Plaster of Paris. Several helpful viewers have pointed this out. This information in the video is inaccurate. Please forgive my misunderstanding.
