As potters, we have to think in multilevel ways. Not only are we striving to find unique decorative surfaces, but we are also thinking about creating the perfect three-dimensional form that can enhance that decoration. What that means for me is that I am constantly experimenting with new alterations in my construction process to create the best canvas for my underglaze paintings. 

In this case, I was experimenting with my new hand extruder tools. I started to create appliques to attach to the outside of some of my forms, but it occurred to me to try and attach them to the inside of the pot. What I came up with were these elegant facets that created a dynamic rim but also literally pointed my eye down to my decorative surface.

Supply List

  • Freshly thrown vase

  • Diamond Core Tools R2 Triangle Hand Held Clay Extruder

  • Diamond Core Tools Trimming Spinner with division hash marks around the rim.

  • Ruler

  • Small piece of poster board

  • Pencil

  • Scissors

  • Small flat eraser (or similar shaped object)

  • Cheese cutter

Taking Measurements

Throw a vase with a slightly recessed, long neck (1). Place your vase in the center of the wheel head. Then, center a Diamond Core Tools Trimming Spinner across the rim of the vase. The purple hash marks around the perimeter demarcate the spinner into fifths as noted by the “¹⁄₅” circled in purple. Using the purple lines, divide the rim of the vase into fifths (2). 

Next, create five triangular, tapered appliques. Using a Diamond Core Tools Triangle Extruder, cut 2-inch clay appliques  from a solid block of clay so there are five in all (3). Now, measure the height of the neck of the vase—measuring from the rim to the shoulder (4).

1 Throw a vase with a long neck. You can alter the measurements to fit your needs. 2 Center a Trimming Spinner over the rim using chopsticks. Mark the rim into fifths. 3 Pull the extruder tool through clay to create 2-inch-long appliques (5 total). 4 Measure the height of the neck of your pot, from rim to shoulder.

Creating a Template

The next step is to create a triangular template used to taper the applique and mark the height of the facet cut. Fold a piece of poster board in half and measure along the fold so it is the same measurement as the vase neck (5). Measure the height of the applique and keep the length of the poster-board template short enough so that it does not touch the bottom edge. Connect the two points to form a triangle, and then cut out the template (6). 

5 Fold poster board and mark the edge the same measurement as the neck height. 6 Cut out a triangle small enough to fit over the top of each clay applique.

Fine Tuning and Attaching the Appliques

Elevate the appliques by setting each on a flat eraser, so they are easier to cut. Then, place the template over the applique. Using a cheese cutter, cut down and around the edges of the template (7). Repeat this process for each of the five appliques. 

Score, apply slip, and attach each clay applique on the inside of the vase along each mark, making sure to attach each firmly and seal them completely to the inner surface (8). 

On the outside of the vase, line up the center of the template to each ¹⁄₅ mark on the rim, then mark the bottom edge at the  point. This denotes the bottom of each of the inner appliques (9). 

7 Elevate the applique, place the template, then cut the edges with a cheese cutter. 8 Score and slip both pieces along the marks, then attach the appliques inside.9 Line up the template along each mark on the neck and mark the bottom point.

Cutting the V-cut Facets

Let the vase dry to a leather-hard state. With the Triangle Extruder, center the V blade along the point created earlier. Cut into the clay very shallowly and pull the tool upward into the clay toward the rim, cutting a little deeper as you move upward. Stop halfway to the top of the rim and pull the tool out (10). 

Center the tool along the top of the rim over one of the V shapes and begin to cut through the clay, so there is at least ¼ inch of clay on either side of the tool’s blade. As the tool moves downward, pull the tool in an outward direction until you meet up with the lower cut. Remove the excess clay (11). Use a wet paint brush along the inner facet to seal and smooth the clay. 

10 Push the extruder tool half way up the neck of the vase then stop. 11 Place the tool into the clay applique and push down until you meet the bottom cut.v

12 Repeat this for all five points around the vase, then refine the edges. You can glaze your vase to accentuate the reverse facets.

Repeat this step for the remaining V-cut facets (12). Let the vase dry slowly. When it is bone dry, bisque fire it to cone 04. Then, glaze it and fire to temperature.
