Create a plaster relief sculpture

This is a great introduction to plaster casting. Fun, easy and great to do with kids. This s a wonderful example of how art can be more than just something you do with a pencil and paper.

Step 1 Creating the negative plug.

Into the canvas lay 3 blocks of modelling clay side by side. There will be a small area left to the side and to the top that you will be able to fill with a block cut to those specific sizes. Once the clay is in smooth it out. You can then make impressions with your chosen implement. In this case I am using an old wooden door stop. Apply some hand cream around the timber with the bright brush.

Step 2 NOTE : Do Not Leave your hands in Plaster while it hardens

Pouring the plaster. Put on your gloves. Plaster is mixed 2 parts plaster to 1 part water. In a plastic bucket mix up the plaster with the water. It should be the viscosity of thickened cream. You can then pour the plaster into the mould. Make sure the plaster reaches the top of the frame and smooth it off with a palette knife.

Step 3 Undercoating.

Paint a thin coat of Paynes Grey over the sculpture. Use the large flat brush for this and make it as consistent as you can. Let this dry.

Step 4 Top coating.

Squeeze out some Metallic Blue and dry brush it over the high parts. Let this dry. Next lay some Metallic Purple over the top.

Step 5 Varnishing.

Lastly squeeze out some gloss medium and cover the entire surface with the Taklon brush. This step is optional and not in the video but I think it will add a nice sheen to the finished product.
