Understanding Silicon Moulds

Silicon moulds are flexible moulds typically made from silicone rubber. They come in various shapes and sizes, allowing for a wide range of design possibilities. These molds can capture intricate details and textures, making them ideal for replicating complex patterns or shapes in pottery. My favourites are redesign with prima

Choosing the Right Clay

When using silicon molds for pottery, selecting the right clay is crucial. Opt for clay that is not too wet. Rolling it out a couple of times on a ware board can dry it enough to make it easier to use. .Ensure that the clay is free of air bubbles before using it with the mold.

Preparing the Mould

Before using a silicon mold, it’s essential to prepare it properly to ensure successful casting. Begin by cleaning the mold to remove any dust or debris. Depending on the type of mold, you may need to apply a release agent to prevent the clay from sticking. Common release agents include talcum powder, cornstarch, or a silicone spray. Be sure to follow the manufacturer’s instructions when applying the release agent to achieve the best results. I use corn flour/ corn starch and dust it on using a soft paint brush.

Casting with Silicon Moulds

1. Rolling Out the Clay: Roll out a slab of clay to the desired thickness using a rolling pin or slab roller. Ensure that the slab is large enough to cover the surface area of the mold.
2. Pressing the Clay into the Mould: Gently press the clay slab into the mould, ensuring that it conforms to the shape of the mould and captures all the details. Use your fingers or a clay tool to press the clay firmly into the mould.
3. Trimming Excess Clay: Carefully trim away any excess clay using a firm rib scraping over the area working from the middle toward the edges to avoid pulling the clay out of the mold . Pay attention to the edges to ensure a clean finish. Use your scoring tool while the clay is still supported by the mold.
4. Releasing the Clay: Once the clay has been pressed into the mold, carefully bend the mold away from the clay to release the formed clay piece. Take your time to avoid damaging the delicate details.
5. Finishing Touches: After releasing the clay from the mould, you may need to do some additional trimming or refining to perfect the shape. Smooth out any rough edges and make any necessary adjustments before allowing the clay to dry.

Tips for Success

• Experiment with Different Moulds: Don’t be afraid to experiment with a variety of silicon moulds to discover new shapes and textures.
• Proper Care and Maintenance: Clean your silicon moulds after each use to prolong their lifespan. Store them in a cool, dry place away from direct sunlight.
• Practice Patience: Working with silicon moulds requires patience and precision. Take your time and pay attention to detail for the best results.
