Stock clay stamps are made in USA, and can be ordered in a range of sizes. Select the size with the drop down menu under each design. The white areas shown will be the final mark that will press into the clay (the raised part of the stamp surface). All designs are copyright (C) 2009-2023 SOCWELL LLC. All stock stamps are made in house and custom versions are available (by e-mail request) if needed in other surface materials for underglaze transfer, PMC, or ink on paper. All stamp tools are made of high quality laser cut maple wood and can be used for many years of creative work. Depth of the mark is about 1/8" (about half the wall thickness of a piece made on the wheel) and made for ceramic clays.
