Firstly I rolled out buff clay about 1cm thick and wide enough to make a wall around to contain the liquid plaster. I picked three books to use to indent into the clay. I used oil to grease up the sides so they wouldn't stick to the clay. I pressed firmly into and evenly in the clay. Now it was time to make the walls around the clay these need to be sturdy and make sure there are no holes so the plaster does not escape through.
Next was to mix up a batch of plaster using plaster powder and water, moving very quickly as you go. Make sure you can see the top of the mound so that's how you know you have enough powder next get your hands in and stir removing all lumps. I then poured the plaster in my clay mould. and waited for 20 minutes.
As soon as the plaster had dried completely carefully remove the clay by peeling the clay back. Fire the clay mould to use for later.
After the clay had been fired I used it to make a glass mould. I painted the words "footsteps on broken glass" using luster and then fired it in the kiln.
The outcome didn't work as well as I had hoped because the glass didn't fall into the moulds as well but I liked the process and will use it again.
