Create elegant square ceramic plates, dishes, bowls, and slab-built pieces with our Bastille slump mold for clay. This 3D printed plastic mold is designed to help you form clean, repeatable shapes with a softly rounded square profile and consistent results.
The Bastille design is ideal for makers who want to move beyond round forms while keeping a smooth and balanced look. It can be used for both plates and bowl forms, depending on the clay placement and the depth you choose, making it a practical option for pottery studios, home ceramic practice, and coordinated handmade tableware collections.
Like all our molds, Bastille is designed and made by us at DIY Project Depot, with close attention to durability, ease of use, and reliable everyday workshop performance.
To use a slump mold, roll out a clay slab and gently lay it inside the mold so the clay drops into the form under its own weight. Then press it carefully into place, compress the surface, trim the rim, and allow it to stiffen to leather-hard before removing. This technique is beginner-friendly and makes it easier to achieve smooth, even, repeatable shapes.
Size options
The mold is available in multiple sizes to help you create flower-shaped plates or bowls that suit your project.
- Square mold sides: 12 to 36 cm (4.7" to 14.2")
- Mold depth: 5 to 17 cm (2.0" to 6.7")
Please note that the final fired ceramic piece will usually be smaller than the mold, due to normal clay shrinkage during drying and firing. For many clay bodies, total shrinkage is often around 10–12%, though this can vary depending on the clay and firing temperature.
