Examples of stamps & rollers for clay  Ceramic Mugs made by Potter's Fire, Nigel Hoyle, Susan Abramovitz, Terrice Bassler, Harry Peck, and Paul Christian, photos provided by the artist Thank you! Most stamps for clay are of two main types, either maker's marks (chop) or a logo / design to decorate the surface of your work. Maker's marks are usually smaller in the size range of 1/4" to 1-1/2" (about 8 mm to 38 mm). Stamps with a logo for mugs or similar vessels are usually larger than 1-1/2", with 2" to 3" sizes being the most common sizes to use. Lets first look at an example of a logo stamp and how we make that from original artwork that might be supplied by your customer who is looking to have some pieces made.  Logo example shown by permission of COOPERS CREEK POTTERY (cooperscreekpottery.com) and their customer the Fannin County Chamber of Commerce.  As you can see in the example above, in the final mark in clay (lower right image) the multiple depth in the stamp really shows up mostly looking about the same in the clay. The reason we cut stamps in more than one depth is mostly for the function of the stamp as you press into the clay. For example, the letters and middle areas of the stamp press in first to allow them a head start on making a nice clear mark. Next the blue areas push in and that allows overlap like the fishing line and circle borders to not look like one object as a physical mark in the clay. Each design is different and many stamps work best as single level stamp, but we do have the ability to make a 2 level stamp when it will work out better for you as the clay artist.  We are sometimes asked why not just use any rubber stamp, many ceramic artists use them? The answer is simply how professional of a mark you need to make? As you can see in this nice example a customer sent to us, the same clay marked with a regular rubber stamp and marked with our Signature Writer (R) Surface leave two very different marks in clay. Rubber stamps are not really made for marking clay, they are made for transfer of liquid to paper. And we make rubber stamps also for transfer of underglaze to bisqueware, but if you want to mark a deep, crisp, and detailed image into clay our surface will give you superior results. The most common need for a clay stamp is the chop or maker's mark used to sign your work. These are usually made using our Signature Writer (R) Surface, the black surface you see in the photos. We have options of wood or pewter handles and the shape and size often determine which style of handle will fit your design the best. Maker's marks are often best when made simple, the less total surface area the easier the stamp will be to use. These examples show rather complex designs, but the easiest to use would be just simple initials or a single graphic or signature that we can take from a photo of your actual signature on paper. The smaller and simpler the mark the longer you will have to stamp in clay as it starts to firm up. If you want to stamp after you trim, a stamp under 1/2 inch (about 13 mm) is probably the best option for results you will like.  Video demo of our stamps being used along with support inside the pot  Pewter handles with Signature Writer (R) Surface, our best stamps for detail in marking clay. This material is best used with ceramic, polymer, or precious metal clays. Use a release agent like vegetable oil or similar on the stamp surface for best results in stamping wet clays. For PMC use the same release agent you use on your other tools. For polymer clays you probably will not need any release agent. The Signature Writer (R) Surface may be cleaned with a tooth brush and soap & water, but should not be heated in the dish washer or with a heat gun. The surface is good to about 250 F but after that can be damaged by heat. This surface is super durable for 1000s of clear crisp marks in clay but be careful not to drop on a concrete floor, that can damage the detail areas of the stamp. The pewter handles are cast in lead free pewter, the whole stamp including handle and surface are made in USA. The Signature Writer (R) Surface is a trademark of Socwell LLC (exclusively sold at www.4clay.com), and is a hard black synthetic resin (not metal) that is laser cut with your design. The Signature Writer (R) Surface we find holds more detail than brass, wood, or acrylic stamps for marking into soft clay. Note that the Signature Writer (R) Surface is water proof, which works great for marking clay in a production environment, but also means it will not work with potter's pads for liquid underglaze transfer. Most production potter's choose this surface for production of mugs with logos, etc. The Signature Writer (R) Surface is the best we make, and in our opinion perhaps the best available. Just don't drop on a concrete floor, dry with a heat gun, or let you dog play with it...those are the 3 most common ways to damage the surface. Otherwise they last for years of stamping into clay.

We went directly to the studio, rolled out a slab of clay and stamped away...they are just perfect.... crisp, easy to read, and sized just right. We are happy potters...
