How to Make a Slump Mold for Pottery
To make a slump mold for pottery, you will need a few basic materials and follow a specific process.
First, gather some clay, a rolling pin, and a bat or piece of plywood.
Start by kneading the clay to remove any air bubbles and make it easier to work with.
Then, roll out the clay to your desired thickness and shape it into a slab large enough to accommodate your pottery piece.
Next, place the slab of clay onto the bat or plywood and use a variety of tools to create curves, contours, or textures on the clay surface.
These alterations will determine the final shape and design of your slump mold.
Once you are satisfied with the mold’s appearance, let it dry completely.
This usually takes a few days, depending on the thickness of the clay.
Afterward, you can use your slump mold for pottery by placing rolled clay slabs or other pieces onto it and letting gravity cause the clay to slump into the desired shape.
Remember to add some release agent, like vegetable oil or a commercial release spray, to prevent the clay from sticking to the mold.
By following these steps, you can create your own slump mold for pottery and explore a new technique in your ceramic work.

Techniques For Making A Slump Mold For Pottery
Creating a slump mold for pottery involves a variety of techniques that can help you shape clay into beautiful and functional forms. Here are some techniques to consider when making a slump mold:
-
Texturing the mold: Before shaping the mold, you can add texture to the clay surface. This can be done by impressing objects onto the slab, creating a unique pattern or design.
-
Adding handles or feet: If you plan to make a bowl or a plate with a footring, you can attach small clay coils to the bottom of the mold to create feet. Similarly, you can attach handles to the sides of the mold if desired.
-
Sculpting the mold: Instead of using a ceramic or glass object as a mold, you can sculpt your own form using clay. This allows for more artistic freedom and customization.
-
Layering techniques: To create more complex molds or multiple parts, you can use layering techniques. This involves stacking and joining multiple slabs of clay together to form the mold.
-
Experimenting with shapes: Don’t limit yourself to traditional forms. Play around with different shapes and sizes to create unique and innovative slump molds.
By exploring and experimenting with these techniques, you can enhance the creative possibilities of your slump mold making process.
- Textured mold surface

Tips And Tricks For Creating A Slump Mold For Pottery
Creating a slump mold for pottery can be a fun and rewarding experience. Here are some tips and tricks to help you along the way:
- Use a non-stick surface: To prevent your clay from sticking to the wooden board, cover it with plastic wrap or a non-stick cloth. This will make it easier to remove the mold object and shape the clay.
- Smooth out the edges: After cutting around the mold, make sure to smooth out any uneven or rough edges. This will help create a clean and refined mold.
- Consider size and proportion: When choosing the size and shape of your slump mold, consider the size of your kiln and the proportion of your final ceramic objects. You want to ensure the objects you create using the mold will fit in your kiln for firing.
- Experiment with different materials: While ceramic and glass objects are commonly used as mold objects, don’t be afraid to experiment with other materials such as plastic, metal, or wood. Each material will produce a different texture or finish on your clay objects.
- Practice patience: Allow your slump mold to dry completely before using it. Drying times may vary depending on the thickness of the clay and the humidity in your environment. Rushing the drying process may lead to cracks or warping in the mold.

Frequently Asked Questions
What material is used for slumping molds?
When it comes to creating ceramic slump molds, there are various materials to consider. While options such as pottery plaster, plywood, and insulation foam are commonly used, one intriguing choice stands out – bisque-fired clay. By utilizing the very material that is being molded, it not only offers flexibility in design but also ensures compatibility with the ceramic medium. The use of bisque-fired clay for slump molds enables artists to explore and experiment with unique shapes and textures, adding an element of cohesiveness to the overall ceramic work. Its versatility and potential for artistic expression make it an appealing choice for mold-making in ceramics.
How do you use a slump mold for pottery?
To use a slump mold for pottery, begin by preparing a slab of clay that has been rolled to a thickness of approximately ¼ inch. Next, carefully drape the clay slab over the surface of the mold and gently press or tap it into the desired shape. The weight of the clay and the mold’s contours will help shape the pottery as it gradually takes on the form of the mold. Once the clay is aligned with the mold and sufficiently shaped, it can be left to dry and harden before being removed from the mold for further finishing and firing processes.
What size are slump molds?
Slump molds, also known as slump cone apparatus, come in a standardized size. These molds have internal dimensions that follow a specific configuration. The bottom diameter of the slump mold is 20 cm, the top diameter is 10 cm, and the height measures 30 cm. Additionally, the metallic sheet used for the mold must have a thickness of no less than 1.6 mm. These precise measurements ensure consistency and accuracy in conducting the slump test.
What are some alternative materials that can be used to create a slump mold for pottery?
Some alternative materials that can be used to create a slump mold for pottery include wood and plaster. Wood can be easily shaped and carved into the desired form for the mold. It is a durable material that can withstand the pressure of the clay while allowing for easy release of the finished pottery. Plaster is another commonly used material for creating slump molds. It can be poured or carved into the desired shape and provides a smooth surface for the clay to slump onto. Plaster molds are also reusable, making them a popular choice among potters.
