The White Finishingis a pop-up sponge made with a tight cell material and is less absorbent than the Blue Workhorse. It is excellent for finishing work, final detail and clean-up of surfaces and won’t pull out grog or other materials in the clay body. Think of it like a chamois sponge.
Natural sponges have been used by potters for years. However, the quality of natural sponges can be unpredictable and we try to be environmental conscious about what materials we use and the long term effects. Mudtools sponges are made of a biodegradable and environmentally friendly material that is incredibly durable. Your Mudsponge comes to you compressed for economy of space and for the fun of watching them expand when introduced to water.
