MudTools Pottery MudSponge Absorbent Wheel Throwing Sponge — Orange, Compressed Pop-Up High Absorbency

The MudTools Orange Absorbent MudSponge is a compressed, kidney-shaped pottery sponge that expands in water and gives potters superior moisture control on the wheel.

Designed for wheel throwing and handbuilding, this compact sponge unfolds into a durable, highly absorbent tool that fits comfortably in the hand. Made in the USA from an environmentally friendly material, the MudSponge offers both space-saving shipping and long-lasting use in the studio. It measures 3.75 x 2.63 inches and arrives compressed, popping open the first time you dunk it in water.

How does the MudSponge help control moisture during throwing?

The MudSponge soaks up and releases water precisely where you need it, letting you tame clay consistency without over-wetting. Its material holds more water than many finishing sponges, so you spend less time re-wetting and more time shaping. Because of the sponge’s absorbency, it helps smooth surfaces and remove excess slip while maintaining the clay’s firmness.

• High absorbency reduces frequent dunking and drip on the wheel
• Kidney-rib profile makes targeted moisture application easier
• Durable matrix resists breaking down with regular use

Why choose a compressed pop-up sponge instead of a traditional sponge?

Compressed packaging saves shelf and shipping space, and the MudSponge springs back to full size after its first soak. The compact form makes it convenient to carry in a kit or store in a drawer until needed. Once hydrated, the sponge behaves like a full-size pottery sponge without taking room in transit.

• Ships flat to minimize storage and shipping footprint
• Expands instantly when introduced to water for immediate use
• Easy to tuck into a tools bag or kit when dry

What makes the shape and material suitable for wheel throwing and handbuilding?

The MudSponge is moulded into a traditional kidney-rib silhouette so it nests naturally in the hand for controlled shaping and smoothing. The curved edge follows the contour of pots for even contact, while the flat surfaces aid in flattening and finishing. The material combines absorbency with resilience, so it maintains form through repeated work sessions.

• Kidney-rib shape provides ergonomic grip and surface contouring
• Edges help get into tight curves and under lips without gouging
• Material resists crumbling, lasting through many sessions

How should I care for my MudSponge to extend its life?

Rinse the sponge after use to remove clay and allow it to dry between sessions to prevent mildew. Avoid harsh detergents or wringing too aggressively—gentle squeezing and air drying are best. Periodic rinsing and drying will keep the sponge functional and hygienic for many throws.

• Rinse thoroughly after use to clear clay and slip
• Squeeze gently and air dry; avoid machine spinning
• Store dry to reduce odour and prolong lifespan

Who this is for: The MudTools Orange Absorbent MudSponge is aimed at wheel-throwers and handbuilders who want a compact, dependable sponge that offers excellent water management and ergonomic control. It’s ideal for studio potters, students, and instructors who value space-saving tools, long-lasting materials, and a traditional rib shape that complements typical throwing techniques.
