@rail posted:Another suggestion for building a salt pile: you can use a piece of carved foam and use paint or white glue, or on a piece of wax paper build a pile gradually using a spray bottle with water base urethane clear finish. Start by making a small pile and spray, and add another layer and spray until you have the desired size and profile. When dry, (may take a few days, depending on the size), cut the wax paper around the base if it doesn't release from the pile. Another method would be to use modeling clay, or play-dough to make a pile profile and add the material with paint or white glue. Good luck, and post some pics.
Using urethane finish is a great idea. But, I would skip spraying the inner layers. Just build a loose pile slightly smaller than your target, and build up just enough layers to make it strong enough. This produces a hollow pile which is lighter, uses less material, and makes no difference visually.
