Large plaster mold using frosting method

This video is a compilation of videos from my residency in the Netherlands.  In the videos we are being taught to make a light mold for casting large objects.   First segment covers frosting and subsequent segments cover using burlap to reinforce the mold.  In the end we make a two-part mold for slip casting or press molding.  Please let me know if you want me to demonstrate this in person.
