Why Use a Polymer Rib?
Polymer ribs offer several advantages for ceramic artists. They can be used to smooth clay surfaces, compress clay, refine curves, shape walls, and remove unwanted marks.
The ability to choose between different shapes and firmness levels also means you can select a rib based on the specific task you’re performing.
Polymer Rib for Wheel Throwing
For wheel throwing, polymer ribs can help shape and compress clay while maintaining control over the form. Softer ribs can be useful for smoothing and refining surfaces, while firmer ribs can provide more resistance when compressing and shaping clay.
Different shapes can also make certain tasks easier. Smaller ribs are useful for detailed areas, while wider ribs can cover larger surfaces more efficiently.
Polymer Rib for Handbuilding
Polymer ribs aren’t limited to wheel throwing. They can also be useful for slab building, pinch pots, coil building, and other handbuilding techniques.
A soft rib can help smooth joins and refine surfaces, while a firmer rib can provide greater control when shaping slabs and creating defined edges.
Polymer Rib for Sculpting
Sculptors can also use polymer ribs for refining clay forms. The different shapes allow artists to work on both broad surfaces and smaller details.
A soft rib can be especially useful for smoothing and blending clay without creating overly harsh marks.
How to Choose the Right Polymer Rib
Choosing the right rib depends largely on the type of work you do.
Choose a very soft rib if you primarily want gentle smoothing and surface refinement.
Choose a soft rib if you want a balance between flexibility and control for general clay work.
Choose a firm rib if you need more resistance for throwing, compressing, and shaping clay.
You should also consider the shape. A small rib may be better for detailed work, while a larger rib can save time when smoothing broad surfaces.
The Mudtools Polymer Rib collection offers pottery tools for a wide range of applications. With different shapes, sizes, and firmness levels, these ribs can be useful for throwing, handbuilding, sculpting, smoothing, compressing, and refining clay.
For beginners, starting with a versatile shape can be a good way to learn how polymer ribs feel and perform. Experienced potters may prefer keeping several shapes and firmness levels in their toolkit so they can select the appropriate rib for each project.
Ultimately, the best Polymer Rib depends on your technique, the size of your work, and the level of control or flexibility you need.
