GR Pottery Forms are American Made wood fiber drape molds used for hand-building. With our Forms you can quickly make plates, platters, bowls and dishes in repeating and complementary sizes. They are easy to use, budget friendly and light weight. The Forms are wood, so to make them last for thousands of uses make sure you let them dry in between each use. The timing of making them and removing the Form from the slab is very similar to plaster. If left on too long your clay will crack and the wood will mold or start to get soft. Mold can easily be washed off with dish soap, and if edges get too rough you can use sandpaper to smooth them. Form sizes are measured from the back side of the Form which is also the largest part of the Form. Measurements are approximate. If you are trying to determine what size to make, there are many factors involved. Factors would include: The size of your lip, shrinkage of clay and firing temperature. The Depth of Standard Forms are 3/4 inch. If you want to determine the center/inside measurement, it would be 1.5 inches smaller than the Form measurements.
