Making moulds with Plaster

Making moulds for ceramic work is easy and affordable. To make bowls you can either spray the bowls with a release agent, such as silicone or cover the bowl with a clay layer. This means you can etch or alter the shape to suit before pouring in plaster.

To make my heart mould I formed a solid heart shape and pressed it firmly to the base of a plastic container. After pouring the plaster I jiggle the container to release any bubbles.

Once set, the plaster mould can be easily removed and used. When creating wall hangings it’s important to consider how the piece will be hung. I attach clay using a vinegar and water mix to help with the blending of the clay. Using a small 2cm long piece of straw I cut a hole, so the wire can be used for hanging the ornament when finished.

After about a week of drying, weather dependant, the pieces can be put into the kiln for a bisque firing up to 1040oC. Then once the glaze has been applied, the pieces will receive a second firing, up to 1200oC. Complete.


Kids Market-ing

I love trying to get my kids into making money. Community markets are a great way to teach them the basics of working for their money. Last year I used Vistaprint, and produced stickers for them to sell. I created the image and added the towns name.           If the kids wanted to spend money at the market they had to first earn it, even to buy their lunch!

This year we added plaster crafts to the table, for other kids to buy to take home and paint.

Using a collection of moulds, made with liquid latex, purchased from Trig Instruments, the kids and I worked as a team to produce a selection of plaster crafts. As they were made the morning of the market, once out of the moulds I put them in the oven on a very low heat to speed up the drying process.

The kids also had poster paint at the market, in case kids wanted to paint them while there, and had plastic plates for them to take them home on.
