When I get the sheet of stamps, I cut out the circles as neatly as I can.
Each circle is glued to a wooden spool, found at the craft store. I found the perfect size for my stamps.
I grab a chunk of terra cotta, about, oh...this size
I compress into a ball, and roll in hands with firm pressure, turning the ball into a flat "cookie" shape
The finished cookie shape. I make sure it is totally smooth, and run my finger across the top to burnish the surface
I use a little bit of oil on the stamp so it doesn't stick...just cooking oil, rubbed on with my finger. I press the stamp firmly into the clay. I have to be careful the clay is not too wet and sticky, yet not too dry. This just comes with practice.
The stamped cookie, yay!
I stamp the back with my signature or chop mark. I carved this out of clay and fired it. My initials are hidden in the design.
Repeat. over and over. as needed. Then they have to dry REALLY good! seriously. These are thick, about 3/4 " so it takes about a week. More to be sure. I have fired a few batches too soon in a rush and its not pretty...they explode and I cry. So no rushing. Also, if they are dried too fast, they tend to crack. It is a physics thing that I don't fully understand, but have just learned to feel more intuitively. No drafty areas, no air blowing on them, and in the summer, I dry them in the damp basement.
Once dried, I fire them in the kiln. Since they are not glazed, they can be stacked right on top of one another. The picture above shows a different type of ornament, but the kilns I fire for these cookies looks similar. Stacked up to the top, full of ornaments! The kiln is fired slowly to cone 04 (which is about 2000 degrees F). Just one firing is needed for these guys.
Some assorted trivia and other thoughts about the Scent Cookies:
I make these for bath/soap crafters and candlemakers, often in custom designs (like logos) because they make perfect add ons to their sales and they can be packaged with the oils they use in their products.
