Soldner mixers are made of concrete, which when wet, release the clay. Most mixers chop or squeeze clay with multiple blades. Soldner mixers cut and rotate it in a single motion, spatulating and blending the mix continuously. Use the tub for clay storage. Slake your trimmings, make it your slop barrel or store mixed clay in it.
Replacement parts are standard off the shelf items.
Most mixers are still in use after twenty years. Use the image map at the top of the page to navigate.
