It's a non-woven fabric that provides a smooth surface for clay work. |
|
For hand building or slabs with a rolling pin, use one piece of SlabMat. A piece of rubber shelf liner under the SlabMat will keep it from sliding. Slab roller possibilities: for small slabs, use one piece of full size SlabMat folded in half with the clay sandwiched in between. (If you crease the SlabMat, the crease is permanent.) For long slabs, use two full length sheets of SlabMat or SlabMat can be used in combination with canvas to get one side textured and one smooth. |
|
Yes. Avoid contamination. |
|
You may wipe the surface with a damp sponge, but do not saturate it with water. Allow the SlabMat to dry completely before use. |
|
NO! Talc is a flux. The addition of a flux to a clay body will lower the fusion point and raise the density of the body during firing. If you find that your clay is sticky, you may want to dry the clay somewhat. There are may ways to do this: wedge the clay on plaster or concrete; squeeze the clay into thick coils exposing more surface area to air; or run a thick slab through the slab roller using canvas to absorb moisture. When clay is rolled, the bottom mat absorbs more moisture. If your clay is sticking only on the bottom mat, fold back the top mat and flip the clay upside down onto your work surface. |
|
Each clay contains a different amount of moisture. Roll a few slabs and make note of how the SlabMat responds to your clay. It is best to remove the slab soon after rolling because prolonged wetness may cause the SlabMat to have a waviness. Tip: If you are slow drying flat slabs, place the slabs between pieces of drywall board, also known as gypsum or sheet rock. It is found at home centers, is easily cut with a utility knife, and is inexpensive. |
|
Yes. Cut SlabMat with an Exacto or utility knife. |
|
Everyone has a different hand when cutting, so it will vary with each tool and person. A stainless steel fettling knife is recommended. If you use an Exacto knife or needle tool, cut test on a SlabMat sample to see how hard you can press before you damage the surface. |
|
Store SlabMats flat. To extend the life of SlabMat, avoid excessive heat and direct sunlight. If you must store your SlabMats rolled, roll the mats loosely, then reverse the roll 24 hours before you are to use the mats. |
