Here are two clay tiles I made in my studio clay class in early 2020.
I rolled out a slab of clay and stamped the various designs into it. These stamps were ones that I had made myself. How did I do that? Well, I formed tiny sculptures with raised or incised patterns on them and then I bisque fired them. Then I could use them to press into clay as I did here.
Some of these stamps were simply tiles, and others resemble cylinder seals of antiquity. To use the latter you roll it along, and it makes a continuous pattern in the clay.
To glaze them, I applied various washes or glazes over one another. Primarily I dip glazed the tiles, rotating them as I put different sections into different glazes. As you may remember, glazes are chemical soups, and combining them is not like combining paints, where you can predict the outcome. Instead, the chemical combination of two glazes can give unexpected and surprising results. Which I like!

These are both great. I love that interplay of mark-making, dimensional texture, and the interaction of the colours. They look very tactile and appealing.
Thank you. I’m happy with how these turned out. I had not made my own stamps until the studio clay class and I think it is something with a lot of potential, if I keep up with doing clay work.
They do have an ancient look. (K)
It’s a fun technique, making your own stamps and then using them like this. I was surprised how well the glaze still allowed the details to be shown.
