Sculpture and St Francis Moldmaking 2

See the dark holes? Each and every one must be sealed.


The mold rubber will seep into any tiny gap, so the entire surface is inspected. Any gap between the blocks is sealed with plasticine. That saves wasted (and very expensive rubber) and makes a stronger  mold.







Here's the sculpture after all the holes have been filled.
A thick coat of shellac fills any holes I missed and seals and prepares the surface for mold making.

art is tedious! I go to shellac almost daily to solve something I am in to. Happy Valentines!

Thanks, Theresa. Hope you have flowers and good food today, too!

Hemp has been replaced by fiberglass but Shellac hasn't changed much for centuries, and we wouldn't have it any other way.
