I've heard of sculptors using wire on the inside of their clay sculptures to keep complex structures together, but clay shrinks when it dries and it should crackHow would on to that while keeping they clay from cracking?
How would on to that while keeping they clay from cracking? The clay with metal structures inside is either non-hardening clay that is used to make molds for casting in harder materials or it is polymer clay where the inner core is heavy duty aluminum foil to reduce the amount of clay and support the uniform thinner outer layer during bakingCeramic clay, which both shrinks and is fired, is not made with metal inside - the thicker portions are made hollow, supporting larger upper parts by being allowed to partially dry (leather hard) during the work.
