Only use distilled water in the Clay Hydrator because it does not have impurities, which help prevent molding. When adding clay to the Hydrator, loosely wrap it in a small piece of plastic wrap. Do not wrap it too tightly, because this allows the moisture in the air to get into the clay. Never place clay directly on the sponge, or the water and the clay will make a mess and form slip. Make sure your hands are clean
Each sponge is sized perfectly for the Clay Hydrator, so everything fits together nicely. This bottom sponge should be soaked a little more thoroughly, allowing a small amount of water to rest in the bottom of the base. This water is slowly absorbed through the bottom sponge, and continuously pulled up into the air by the top sponge. During this process, your clay absorbs this much needed moisture and re-hydrates any metal clay. This innovative design creates the perfect environment to keep metal clay hydrated for several months.
Clay Hydrator does not re-hydrate completely bone-dry clay.
Note: When using the clay hydrator, you are creating a moist environment for days, weeks or months at a time which can encourage mold. Distilled water and clean hands are essential.
