Things You'll Need:
- Earthenware air-dry clay
- Small pebbles
- Waterproofing clay sealant
-
Step 1
Pull and condition a piece of clay of the right size for a miniature fireplace. For a standard dollhouse scale of 6:1, this will be a chunk about the size of a golf ball, depending on how big you want to make your fireplace. Use more clay if you want to build a tall chimney section or other large structures as part of your fireplace. Work the clay in your hands to soften it.
-
Step 2
Shape the fireplace's rough form. Slightly flatten the round piece, then press one edge of it against your tabletop to flatten it into the the bottom of the fireplace. Press your thumbs into the center of the shape to form the hollow that will become the hearth. Extend the hollow down to the bottom of the fireplace.
-
Step 3
Refine the shape. Pinch and press the inside hollow of the hearth into the shape you want. Leave it rough for an old peasant's fireplace, but refine it into corners for a more modern or upscale fireplace. Shape the outside edges of the fireplace into a boxy shape by pressing each edge against the tabletop.
-
Step 4
Moisten the surface of the fireplace. Rub a generous amount of water all over the outside surface of the fireplace shape until it glistens. Let the form sit for several minutes until the water soaks in and the surface of the clay is tacky; this will make the clay soft enough to add the stone.
-
Step 5
Add stones. Press small pebbles into the surface of the clay. Position them as densely or far apart as you like. Be sure to press the stones far enough in that they are least half submerged in clay to ensure they stay securely in place.
-
Step 6
Clean the surface of the stones of clay paste. While the clay is still wet, wipe away any clay residue from the exposed stone surfaces using a damp rag.
-
Step 7
Let the clay dry overnight. Apply a coat of waterproofing sealant.
