Metal Clay 101: Moisture Retention and Storage By Kris Kramer
Since the finest creations are made with the freshest of clay, keeping your clay fresh is critical for a good result. Moisture keeps binder in the clay at its peak performance, allowing you to best texture and join clay in your beautiful creations.
Everyone develops his or her particular way to store clay for the short- or long-term. Here are some tools and processes to know about while you develop yours. Many of these tools can be purchased or homemade.
While Working — Parked Clay Never, never leave your clay out exposed to air while you are working on a creation.
Put clay away immediately, even if temporarily. You can quickly pop this clay into a Clay Safe or Vault, or you can hide it under a moisture chamber (see below). I like to place mine in misted plastic food wrap, wrapping the clay in the plastic wrap once or twice to either park it on my workstation or to sit on it (that gets all the air out). Then I can go back to work on my piece until I am finished and it’s time to store the clay properly.
