Salt dough recipe:
1 cup table salt
2 cups plain flour
1 cup water
1 tsp vegetable oil
1 tsp Golden Acrylic Medium Heavy Matte Gel
Add more water/flour to get consistency right.
Stores well wrapped in cling film.
I became quite interested in the properties of salt dough, it may be worth investigating larger additions of acrylic medium as it lends transparency to the mix which makes a material reminiscent of porcelain.
These have been stained using B's Damar Varnish mix tinted with oil paint. Fumes nearly blew my head off, I would never again do so many in one sitting.
