Slab Roller Slabmats
CARE AND USE OF SlabMat
Store SlabMats flat. If you must store your SlabMats rolled, roll the mats loosely. To extend the life of your SlabMat avoid excessive heat and direct sunlight.
To cut a SlabMat to a smaller size, use an Exacto knife or utility knife along with a straight edge.
Cutting clay directly on SlabMat with an Exacto knife or needle tool requires attention to the sharpness and the pressure applied. Perform a cut test on a SlabMat sample to see how hard you can press before you damage the surface. A stainless steel fettling knife is recommended.
Hand Building or slabs with a rolling pin you may use one piece of SlabMat. If your table is slick, use a piece of rubber shelf liner under the SlabMat to keep it from sliding.
Slab roller use: 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. SlabMat can also be used in combination with canvas to get one side textured and one smooth. Place the canvas on the bottom for it to absorb the most water.
DO NOT LEAVE YOUR CLAY ON THE MAT AFTER ROLLING. If you remove your slabs immediately you should be able to roll a few slabs before the SlabMat is too wet. 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, also known as gypsum or sheet rock. It is found at home centers, is easily cut with a utility knife, and is inexpensive. Cover the cut edges with duct tape).
If your clay sticks to the SlabMat your clay may be too wet. Generally, if you can roll out your clay on canvas, you should be able to use SlabMat without sticking. Cornstarch can be used as a release if lightly dusted on the mat. It will burn out in the firing.
(Tips: 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; or run a thick slab through the slab roller using canvas on the bottom to absorb moisture. If you still have a problem, you may want to dry the clay somewhat by wedging the clay on plaster or concrete. You can also squeeze the clay into thick coils exposing more surface area to air dry it).
Use separate pieces of SlabMat for different color clays to avoid contamination.
