That’s all it takes. You’ll notice the clay colors changed. I’ve been benching for the last week and compiled this from an assortment of images after many remounts. So long as you dry the clay off, you can continue to re-use it many times. Just be very careful to not roll anything metallic into it. For example, I had some metal shaving from dremeling some aluminum and I dropped a piece of clay on the floor, embedding metal shavings into the clay.
