The piece is sculpted with Plasticine and cast from fiberglass resin. These are not the best mateials to use but they are cheap and get the job done.
I was inspired by Sylvia's Super Awesome Show, she made it look easy.
Step 1: What you need
Plasticine (oil clay)is used for making the master shape. Real Plasticine is meant to melt hen it gets to about 100C which would make it easy to get out of the mold. Unfortunately mine was a knock off that just caught fire.
Plaster of Paris is for making the mold. you pour it around the Plasticine sculpture.
Not pictured is Lego, for making a box, and plastic wrap or aluminium foil for lining the box.
Step 2: Make the piece
I rolled the clay flat an trimed the excess. Then I made a right angle shape. In the join i added a small sausage to make sure there was proper contact between the pieces. I did not want a mold with gaps.
I cut out a small cylinder and attached it to the top. This created an overhang in the mold that gave me trouble later.
Since i was trying to create a right angle I molded it onto the corner of the kitchen counter.
Cutting the clay is much easier if your tools are lightly oiled.
